Remove Spaces in MailNicknames/Alias In Exchange Online RRS feed

  • Question

  • Hi everyone,

    We have MIM 2016 provisioning our user accounts/email and have run into an issue after migrating to Exchange Online.  When creating mailboxes on-prem, Exchange natively removes spaces (which are illegal characters), but Exchange Online does not seem to do/support this, which leads to the system trying to create a mailbox with an alias with spaces (e.g. john.smith johnson@domain.com vs john.smithjohnson@domain.com).  MIM is just calling a PowerShell script from the portal to run Enable-RemoteMailbox on the user's account.

    Has anyone else encountered this and if so, how did they correct it/get around?  My Exchange Admin says Exchange Online doesn't support this functionality (I've yet to see any documentation either way, and I don't fully trust him), so wanted to see if anyone else has dealt with this?
