Getting Teams and SharePoint Sites to Appear in the Outlook Lookup

Office 365 Groups are No Longer Automatic Mail Groups

Until recently, if you created an office 365 group (usually by creating a Teams or a SharePoint site), you would also be able to send that group mail directly via outlook. Unfortunately, with everyone having the ability to create teams and sites on demand -- and very few people following good naming standards, it's very easy to get your corporate address books cluttered.

Microsoft received a lot of feedback about this clutter and as a result, they disabled the functionality. Existing Office 365 groups are unaffected but if you create a new one, you'll find that you can't locate them in the typeahead when you want to send mail.

You can however, still have your cake and eat it too. You just have to use PowerShell.


Since this is an admin feature and I'm presuming that all admins should be on Multi-Factor authentication now, the instructions are for MFA.  If you're not using MFA, you might want to use different connection commands.

Note that you'll need to replace the pink bits with your own details;

  1. Launch Microsoft Exchange Online PowerShell Module as admin
  2. Connect-EXOPSSession -UserPrincipalName
  3. If your PC is already connected under MFA and you've elected to not be prompted for 15 days, PowerShell now seems to take note of this YAY....
  4. Set-UnifiedGroup -Identity "Office 365 Group Name" -HiddenFromExchangeClientsEnabled:$False

That's it.

You'll probably want to refresh your mail screens but they should start working immediately.
