Migrate mailbox to another domain same Tenant
Hi, In our company, we bought a new domain and we want to move all of our existing mailboxes to the new one. I already have both domains registered in the same tenant. I mean mailto:support@contoso.com to mailto:support@contosola.com etc. May you please give me any advice on the best way to perform this?

forward shared mailbox without a license.
Hi What's really the correct way to enable forwarding on a shared mailbox without a license? On a user mailbox with forwarding enabled, I converted it to a shared mailbox and removed the 365 license. I was surprise mail forwarding was still intact.

M365 Exchange Admin Center intermittently unavailable.
Been dealing with an issue for about a week now where the Exchange Admin Center becomes unavailable for a few minutes at a time. Then comes back, then is unavailable again. It's only the EAC. All the other admin centers (SharePoint, Teams, Security, etc...) are available and it's only within the local network. When I test outside of the network, EAC is available. When I test through a PowerShell connection, it works. When I lose my connection, my colleagues on the network do as well - so it isn't something local to my computer. The one change to the network that was made within the last couple of weeks is DNS scavenging has been turned on.

Exchange admin center Delegation permissions error
I am having a strange issue with Exchange Admin Centre I am signed in as a Global Administrator but when I go to a user's mailbox and then to the delegation tab I get the following error. Failed to get mailbox permissions Error: User is not allowed to call Get-MailboxPermission Is this a bug? I wouldn't think it was a permissions issue as I have been fine for years with my current ones.

Did you convert a Distribution list to a Room list? We still don't support management of Room lists.
When will Exchange Management Shell support the management of room lists?

How to connect programmatically via EWS when MFA is Enforced?
Hi: How can we connect to a mailbox programmatically via EWS when MFA is Enforced? We've tried creating an App Password but still get 401 Unauthorized when trying to connect. How does Microsoft provide for this case, i.e. when MFA is required to be Enforced and at the same time we must connect to a mailbox programmatically? I guess I'm missing something in the Tenant configuration. Thank you! Bob H.

Same alias, multiple domains, different mailboxes
I'm looking for how to set up shared mailboxes such that I have mailto:email address removed for privacy reasons, mailto:email address removed for privacy reasons, and mailto:email address removed for privacy reasons on different shared mailboxes. 365 Admin Center won't let me. Exchange Admin Center lets me, but then it doesn't actually work.
