A Look at Exchange Server 2013 Resource Mailboxes

Resource mailboxes have been around for a few versions of Exchange Server, and Exchange Server 2013 brings us a few improvements in how they are managed.

There are two types of resource mailboxes:

  • Room mailboxes are for fixed locations such as meeting rooms or conference facilities
  • Equipment mailboxes are for items that are not fixed to a location, such as laptops or vehicles

Exchange 2013 puts resource mailboxes under their own section of the Exchange Administration Center. Both room and equipment mailboxes are managed in this same section.

A Look at Exchange Server 2013 Resource Mailboxes

One of the immediate improvements is that you are able to set the booking policy or assign delegates during the creation of the resource mailbox, rather than as a secondary task after the mailbox is created.

After the mailbox has been created there are a few additional properties you can customize. The booking options can be further tuned with regards to recurring meetings, booking horizon, and custom replies.

You can also easily configure a MailTip for the resource mailbox.

The text that you place in the MailTip will appear automatically when people add the room or resource mailbox to a meeting request in Outlook. Although in my opinion the MailTip needs some color to draw the person’s attention to it.

Finally, an interesting default setting is the disabling of email address policies. This does make sense as most resource mailboxes are for internal use only, so having email address policies assigning multiple SMTP addresses to resource mailboxes is usually not necessary.

Overall it appears that room and resource mailboxes are a feature that has matured over the previous versions of Exchange Server and now receive just a few minor improvements to make them simpler to manage.

    HI Paul, I realize this is older post but.. I do have a plural sight account.

    We are running Exchange 2013 with resource room booking, I would like to use a template to reply to room requests with procedures and attachments, is this possible with Exchnage 2013?

    Hello,
    We have Exchange 2016 and some users that has there email forwarding to a sharedmailbox (“Team box”).
    When one of this users receive a meeting invitation on a room, this meeting appear in the room’s calendar and the sharedmailbox’s calendar.

    Is there a way that the meeting appear in the room’s calendar and the user’s calendar.

    Thanks in advance.

    Hello Paul or anybody else that can help,

    I have two mbx rooms and we need to configure them in the way that a specific user receive an email notification every time someone add an event to its calendars.

    Is that possible? Thank you in advance!

    How do we apply a specific sharing policy to room mailboxes? We might like to have a more or a less restrictive sharing than is allowed for regular users. I created a ConfRmSharing policy….but the web-UI does not present an option to choose sharing policies (although it does from User mailboxes). If we find a PS way to do it, will the policy actually work?

    Hi All,
    Is there a technical difference between the Room Mailbox and Equipment Mailbox?
    I checked and find out all the attribute are the same.

    Any idea on this?

    Paul, did something change in Exchange 2016 regarding the Rooms button in Outlook when scheduling a meeting? It makes a GC call every time it’s clicked, instead of finding the rooms in the OAB. We didn’t have this issue in Exchange 2010, and it’s driving us nuts. The GC call times out and displays a partial list of rooms, but if you click Rooms a second time, it immediately displays all the rooms?

    Any ideas on this?

    Hi Paul,

    Is there any option to say that “Your Conference room is booked” instead of getting the default message that “delegate has accepted the meeting on behalf of room mailbox”?

  10. JonasB 4 Oct 2017 Reply

    I miss the tab “Resource In-Policy Requests” found in EMC for Exchange 2010. Microsoft should have implemented it in Exchange 2016 EAC as well in my opinion. In large organizations it is crucial to be able to restrict the booking of certain rooms and equipment in an easy way. You can’t expect a Helpdesk to run Powershell commands in order to fix this.

    Hi Paul,
    We run Exchange 2010 and have about 8 RoomMailboxes setup. Management is for staff at the Hospitality desk only, so Delegation is set. (No other users making any bookings directly) The Desk would like to use standardized (color)categories to manage the status or use of the rooms a bit better and provide some visual aid when multiple calendars are opened in Outlook. We need 5-8 categories of color and name. Currently they use colors, but cannot rename the tags or labels on the boxes themselves.
    Currently I have an permission or rights issue: Even if I set the ‘Full-Access permission’ on the box the staff is unable to rename existing Categories in the boxes. Creating a new seems possible, but we would like to use the existing cat’s on the calendar items. We have about 2 years worth of scheduled appointments both future and history that we want to keep. Do you have any advise on the minimum rights required to make changes to the labels?

    thank you in advance!
    This Q&A-list really helps in finding clever ways to use Exchange!

    Good write up. Plain and simple in setting up a resource.

    We recently migrated from Exchange 2007 to Exchange 2013. With that, I had the task of migrating calendars from Public Folders to Calendars in the Resources tab. Fairly simple.

    A user mentioned to me that in Public Folders, an organizer would create a “New Appointment” and invite Attendees and when they responded, the organizer would receive an email of their response. This doesn’t seem to occur in Resource Calendars. Is there a configuration that allows responses back to an organizer? (The organizer is not attending the meeting)

    Hi Paul,

    Would there be a way to forward the emails received by a Resource mailbox to another mailbox? I am trying to check this option in Exchange 2013. In Exchange 2007, I could see Delivery Option under mailbox properties but not in Exchange 2013, for Resource mailbox.

    I am aware that we could easily set a rule in Outlook for mail forwarding. But I tried it as well by taking the ownership of the Resource mailbox. It just does not work. Any help would be really great.

    Thanks,
    Saura

        Thanks for reply. We got users at Director level who do not want to check multiple mailboxes and want the emails to get forwarded. So, they have asked to set a rule for auto-forward of emails to their mailboxes and the original mail resides in the Resource mailbox. I could do that with Exchange 2007 Delivery Options. But, I am unable to see that in Exchange 2013.

        Regards,

            OK, there is a mailbox for themselves and then other shared mailbox for the team and another shared mailbox for business reports etc etc. This is how the setup is. So, the additional mailboxes are configured in Outlook in the normal way.

            Mailboxes shows below each other. But, people need to expand the mailboxes to see the folders and then the sub-folders. It sometimes becomes confusing with multiple mailboxes and lot of scrolling up and down. Hence, I think the request was made for an auto-forward of the mails. So, all the information can be seen in the same mailbox and no more scrolling up and down.

            Hope, I am making sense.

    Paul, great article, very useful information. What would be a good way to create a shared calendar that users could invite when they setup appointments? For e.g. a company wide calendar that is mainly used for events such as All staff meetings etc. This shared calendar would always be Free and should allow for double bookings as well, as it’s just a placeholder. Also, would like to publish this shared calendar to the Intranet. My thinking was to create a fake user and setup the Calendar properties to Always Accept. Any better suggestions? Thanks in advance!

    I got a problem after migrate the resource room from exc2k7 to exc2k13..the problem is when we set the schedule for a meeting, the schedule always changed the interval time booked room after 15 minutes for every each room.

    for ex:
    – we set the schedule meeting for a resource room from 1 PM – 2 PM, after 15 minutes the resource room meeting will be change automatically the schedule to be 1 PM – 1.16 PM..so the room calendar will be available for used.

    We’ve come up with an interesting way to give our users the ability to see larger images/photos for Exchange resources in addition to the thumbnail that appears in Outlook. Images are automatically created in 8 different sizes and stored at URL’s like this:

    https://.com/ews/Exchange.asmx/s/GetUserPhoto?email=&size=HR48x48
    https://.com/ews/Exchange.asmx/s/GetUserPhoto?email=&size=HR96x96

    I have a question about “pools”. Is there a way to create a resource pool in Exchange 2013? This would be great for car pools, where you just want to book a car, and any available car would be booked? I’ve read through all the comments and seen that someone allowed conflicts, and I see that it would be possible to allow 4 conflicts if there were 4 cars for example. But then it would be really hard to administer since noone knew which person should have which car. Could it maybe be done with delegation? or is there a really smooth way to do this that I havent found yet?

    I am trying to squeeze as much power out of Exchange as possible here 😉

      During a co-existence you should manage the mailbox with the version of the tools that match the version of the server it is hosted on.

      There’s no special steps that I know of to migrate the permissions and other configurations of the room mailbox. Just migrate the mailbox to the new server and it should continue working as before.

      Do it with a test mailbox first if you want to be sure.

    In Exchange 2010 Resource Room Mailboxes I could add resource custom properties, such as Whiteboard, TV, DVD, WebAccess, Multidirection Speaker phone. In other words, I could show room amenities while I selected a conference room. I cannot figure how to do this in Exchange 2013 Resource Room Mailboxes.

    BTW, these items are not considered check-out worthy and only come with the room.

    We are moving to an Exchange 2013 environment from Exchange 2007. We currently use a third-party room scheduling system and are moving away from that to the native room scheduling in Exchange/Outlook 2013. One thing I haven’t been able to figure out yet is how to include a picture of a resource. I can use the Set-UserPhoto command, but it only allows a tiny thumbnail. I’m looking to be able to show a full size picture of a room so a user can see the room layout. How can I do that?

    We recently upgraded to Exchange 2013, and several of my users have been setup as rooms to ease with schedulers being able to book appointments for them as the auto accept features seem to work better for a room rather than a mailbox. It looks like I have had an unintended problem though that OWA does not work for a room. I do not see any options for it under the resources options and I have not found anything about OWA and resources from searches other than how to manage resource settings through OWA. Any idea on how to OWA-enable a resource in Exchange 2013?

    Hi Paul
    Great article (like all of yours), keep it up.

    I have a question on allowing conflicts for recurring meetings.
    If I AllowConflicts $True, single and recurring meetings are double booked. I thought Double booking are never allowed, no matter what the setting and that these settings just apply to recurring meetings, by deciding how many conflicts there are before rejecting the lot.
    My present settings are:
    AllowRecurringMeetings $True
    AllowConflicts $False
    ConflictPercentageAllowed 20
    MaximumConflictInstances 0

    If there is 1 conflict, all meetings are declined.
    Is there another setting I need somewhere?

      MaximumConflictInstances 0 means no conflicts are allowed for new recurring meetings.

      AllowConflicts $True means the other conflict settings (percentage and max instances) are ignored. So this would override the setting above.

      If you want to allow *some* conflicts set AllowConflicts to $false and use the ConflictPercentageAllowed and MaximumConflictInstances values to control how much conflict you’re willing to allow.

        Thanks Paul. I have applied those settings and that seems to work.
        I was put crook by this article http://blogs.technet.com/b/exchange/archive/2011/02/07/3411956.aspx
        It gives a clear indication of how it works, but as we have found out, is inaccurate.
        Do you know if that article was about how Microsoft wanted it to work and the present situation is a fall-back from problems implementing it?

          Hi Paul. The article states that conflicts will always be declined and that AllowConflicts:$True will bi-pass the Max conflicts and %.
          Whereas I have found AllowConflicts:$True allows conflicts outright and all bookings are accepted and double bookings result.
          Plus When AllowConflicts:$False, ConflictPercentageAllowed 20 and MaximumConflictInstances 0, any conflict with recurring meeting will result in a total decline. It works if I set MaximumConflictInstances 3 (or anything other than 0)
          This concurs with you reply on July 1, but is contrary to the TechNet article text and flowchart.

    We’re having a strange issue with our resources. We finished our migration from exchange 2007 to exchange 2013. We do not use public folders so we did not do anything with migrating public folders.

    We stopped all services on the exchange 2007 servers because migration was done. As soon as we did this conference room resources no longer worked (error: can directly book this room). Once we mounted the 2007 public folder database the resources worked correctly.

    What did we miss? Any help is appreciated. Does 2013 resources still use the public folder system folder?

      Hi,

      we have the same issue when migrating from Exchange2010 to Exchange2016. After dismounting the PublicFolder-DBs on Exchange2010, direct booking of rooms is not working anymore. Will it work again, after removing the publicfolder-DBs on Exchange2010 completly or after Deinstall Exchange 2010 completely from Exchange-Organisation?

      Thanks for answer, René

        I’m having this exact issue. Did you find a resolution?

    Hi Paul,

    I’ve just completed a migration from Exchange 2003, through Exchange 2010, to Exchange 2013. I noticed just today that mailboxes that had been resources in Ex2003 are now allowing double-booking. In Exchange Administration Center some show up in the Mailboxes section and others in the Shared section – none in the Resources section.
    Using the shell I tried to change some to resources (Set-Mailbox MarketingDept1 -Type Room). Shell now tells me that they are indeed rooms (Get-Mailbox -Identity MarketingDept1 | Format-List RecipientTypeDetails) but they haven’t moved in Administration Center and when I edit them I don’t see the booking options, etc.
    How should I be converting these old Ex2003 resources to Ex2013 resources?

    Thanks, Tim

    Hi,

    Does Shared mailbox still exist in Exchange 2013?

    If we migrate ‘shared’ mailbox type from Exchange 2010 to Exchange 2013, will it stay as ‘shared’ mailbox?

    Thanks

    Thanks Paul, and that is very true. I have noticed strange output in the 2013 shell viewing 2007

    FYI after migrating a room I could modify the object but was still experiencing the error
    I noticed that Booking delegates lists “Use customized setting to accept or decline booking requests”
    After I changed the option to: Accept or decline booking requests automatically, the “Use customized…” option disappeared and so did the error

    HI Paul
    I am migrating from 2007 and have just introduced 2013.
    I can view mailboxes, groups and contacts but when I try and view one of the resources I see the error:
    Cannot open mailbox /o=Company/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=2007MBXServer/cn=Microsoft System Attendant.
    Presumably resources are particular and require migration to 2013 before they can be viewed?
    Thanks

        Sorry, in the EAC
        I can view their properties in the 2013 EAC (mailboxes not yet migrated, DL’s also not upgraded)
        I receive the error when I try to read the properties of the resource mailboxes in the 2013 EAC

            Can we see room mailbox list from shared mailbox to book a meeting?
            Ex: User ‘X’ has full access permissions on shared mailbox ‘B’ and this user wants to book a meeting room from ‘B’… Is it possible.

    I notice there is an option for “Custom” rooms in the Room List. Is this configurable client-side? If so I’m not finding how to. This would be a great feature so I can create my own room lists if they have not been set up on the server.

    Is there any option in exchange to make this possible?

    It concerns the via Outlook directly reserve a meeting room, coffee, beamer etc. in such a way that looks or the space actually available and then is secured. The person who reserves also gets a message. Also ushers in a certain way to see what is going on in the Chamber is needed resources.

    Have there been any improvements in the following two shortcomings of booking meetings with Exchange:
    – Meetings set as Free to a resource allow double-bookings (could be avoided if there was a way to set a rule to deny these meeting requests).
    – If the resource is unavailable, the appointment on the client can still be sent to all the recipients. Ideally this would be stopped before it gets sent altogether, like Direct Booking in Exchange 2003.

    Good article, I am impressed with the progress that Microsoft are making with Room and Resource mailboxes. Coming from a company that used an expensive third party room booking solution, that they hardly use 60% of its full feature set, I can really see that this would potentially be viewed as a possible replacement. The only issue I forsee is that the orgs users use a wide variety of Outlook clients so possibly could be a problem? Or would they have to use OWA?

    Agree with the point about a bit of colour required on the Mail Tip. An org’s users would need something to catch their eye.

      Say what you will, but Lotus Notes and Domino has had these features for years. It’s a far more manageable and cost effective resource management system, even if the mail template has less user options then Outlook.

        Have been managing Lotus and Domino for 10+ years, and Rooms and resources feature in domino is terrible.. We have 1000’s of rooms that we manage and its the most difficult thing to maintain. Exchange does it a lot better, each room is its own mailbox and managed properly..
