Hi Paul,

Interesting question to you 🙂
Scenario:
3 organisations are merging.
Organisation A, B and C.
All organisations have their own Office 365 tenants.
Organisations A and B are part of one parent Office 365 tenant.
Organisation C has its own Office 365 domain and not part of the parent that A and B are part of.
The email domain for all 3 organisations are to be changed and will become a new email domain.
Since organisations A and B are already part of one parent domain, the change wont be dramatic, as the new email domain can be added as an alias and wont affect the logins for the users. Is that correct to assume ?
But how can the new email domain be integrated into Organisation C, without affecting the users ?
One way I can think of is having the new email domain hosted for Organisation C at the other parent domain and have the emails coming to the new domain forwarded onto the email domain at Organisation C. That will solve the incoming email issue once the new email domain is setup. but how can the users for organisation C respond to those emails using the new domain ?
Option of migrating the users’ mailboxes of organisation C, to the parent tenant owning orgs A and B are not an option, due to affect to org C users.
Please assist with your expertise.

What if the mailbox for a user is only created in O365 (as not migrated from on prem) but I need to add other email addresses that I have on prem, can the email address policies on prem apply to mailboxes created in O365?

Hi Paul,

What if we need to find users that don’t have a certain domain as an alias or Primary SMTP address. When we do get-mailbox, it list’s all the email address of the user. I tried a filter with -notlike, but it seems to return all users again. Below is what I ran:

$Users = Get-User -RecipientTypeDetails UserMailbox -Resultsize Unlimited | Where {$_.useraccountcontrol -notlike “*accountdisabled*”} | Get-mailbox | where {$_.emailaddresses -notlike “*@domain.net”}

what I’m trying to do is find users missing @domain.net

Hi- I am currently in an office with 21 employees and 3 seperate email domains. We want to somehow create one Calendar for our Conference Room that can automatically integrate with everyones existing exchange calendar, to be able to see when the room is booked or not booked. There are big companies that do this for you but usually its for many different rooms and it is expensive. I have heard this might be possible using Powershell but I am not sure how to go about doing this. Do all the 365 admins have download powershell? Please help!

In reply to Dara. If they need to send as different email addresses, the only way to do that is create separate mailboxes and give them send-as rights for each one. Shared mailboxes work fine for this purpose. Unfortunately Exchange/Outlook still don't allow us to choose an alias of our own mailbox to send as, it needs to be another mailbox.
