Hi,
Some groups are visible in outlook, and some are not.

I did a test a last week creating a new team, and it still hasn't showed. I also disabled the "hide from global adress list" switch.

If I just edit the URL, I reach the groups inbox in OWA so I know it's working and receiving emails. I can star it as a favourite, and it gets listed in the "Favourites" node, but disappears after some time.

Added some test members in this group, and they report the same behaviour.

My older teams/groups are visible in outlook and working as expected. I created a second test group today, but it's the same with this one.

Any ideas?

    Team-enabled Groups are hidden from Exchange clients by default, you can control this by toggling the value for the HiddenFromExchangeClientsEnabled switch: 

    Set-UnifiedGroup groupname -HiddenFromExchangeClientsEnabled:$false

    Hi @GonWild

    Do suggestion above from michev help?

    For the usage of this parameter we can refer to the official document: Set-UnifiedGroup

    The HiddenFromExchangeClientsEnabled switch specifies whether the Microsoft 365 Group is hidden from Outlook clients connected to Microsoft 365.

    To enable this setting, you don't need to specify a value with this switch. The Microsoft 365 Group is hidden from Outlook experiences. The group isn't visible in the Outlook left-hand navigation and isn't be visible in the global address list (GAL). The group name won't resolve during the creation a new message in Outlook. The group can still receive messages, but users can't search for or browse to the group in Outlook or Outlook on the web. Users also can't find the group by using the Discover option in Outlook on the web. Additionally, the HiddenFromAddressListsEnabled property will also be set to true to prevent the group from showing in the GAL and in the Offline Address Book (OAB).

    To disable this setting, use this exact syntax: -HiddenFromExchangeClientsEnabled:$false. The Microsoft 365 Group is not hidden from Outlook experiences. The group will be visible in the GAL and other address lists. This is the default value.
