SOME Teams not showing up in Groups within Outlook

I have just rolled out Microsoft Teams for our company and created  a couple dozen Teams and added members to them. Most of those Teams appeared automatically in Outlook as Groups, but not all of them appear. The ones that don't also don't seem to be searchable. They were all created from within the Teams desktop app directly in the same manner and I'm an owner in all cases. Is there a setting I've missed or a way to manually get a Team to show up in Outlook Groups?

To be clear, I'm NOT looking for threaded conversation to go there or anything. I'd just like to use the Team Calendar but the associated Team isn't appearing.


OK, It appears that this is new functionality rolled out in late June of 2018. It used to be that Microsoft Teams, by default, all appeared under the "Groups" heading in Outlook by default but there was a lot of noise from admins that they did not want all Teams to appear there for various and legitimate reasons. Based on this feedback, the functionality was changed on our around June 28th of 2018 to hide all Teams from Outlook clients by default.

In order for a Team to show up under "Groups" in the Outlook desktop client, you must connect to Exchange Online PowerShell ( and then run the following cmdlet:

Set-UnifiedGroup -Identity "<Group Name>" -HiddenFromExchangeClientsEnabled:$false

Note that .NET Framework 4.7.2 must be installed on the machine from where you are performing this command, as the -HiddenFromExchangeClientsEnabled and the -HiddenFromAddressListsEnabled (which may also be required for this to work? We did it before finding the switch relating to Clients) switches were added with the 4.7.2 Framework release. Find the standalone .NET 4.7.2 Framework installer here:
