Missing Apps such as Email, Calendar and Groups in OWA private group
I also have this problem too. I believe this has to do with the Group being created in hybrid or Exchange on-prem (something along those lines). We've since migrated to Online, but we have these legacy Groups with these problems now.
Trying to find a way to add these apps (just the Calendar, really) to the Group without deleting the Group...
EDIT: Confirming that the cmdlet "Set-UnifiedGroup -Identity "NAMEOFGROUP" -HiddenFromExchangeClientsEnabled:$false" works! It took awhile for those missing apps to show back up, but eventually they did. 🙂
To complete the answer that helped me - You can Run this command to see the options that are disabled and enabled:
Get-UnifiedGroup -Identity "GROUP_NAME" | fl HiddenFromExchangeClientsEnabled, HiddenFromAddressListsEnabled, AlwaysSubscribeMembersToCalendarEvents
HiddenFromExchangeClientsEnabled : True
HiddenFromAddressListsEnabled : False
AlwaysSubscribeMembersToCalendarEvents : False
The default for the Group should be:
HiddenFromExchangeClientsEnabled : False
HiddenFromAddressListsEnabled : False
AlwaysSubscribeMembersToCalendarEvents : True
