VasilMichevHi thanks for your reply.

They are already part of the group. I actually added them with the command you suggested me to.

Here a shortened version of the Get-UnifiedGroup of the group I am talking about:
AccessType : Private
WelcomeMessageEnabled : True
GroupMemberCount : 64
GroupExternalMemberCount : 8
AllowAddGuests : True
HiddenFromExchangeClientsEnabled : False
DisplayName : Global Calendar
RecipientType : MailUniversalDistributionGroup
RecipientTypeDetails : GroupMailbox

 

If you need more information I will provide them 🙂

Adding them to the Group is not enough, you need to also add them to the subscribers list:

Add-UnifiedGroupLinks groupname -LinkType Subscribers -Links email address removed for privacy reasons

    Thank you, VasilMichev . I followed your advice, but it's still not appearing. I double-checked using:

     

    Get-UnifiedGroupLinks -Identity $global_calendar.ObjectId -LinkType "Subscribers" | Select DisplayName

     

    The users are listed as Subscribers, but the calendar is still not visible in either Outlook Web Access or the standard Outlook client.

     

    Do you have any other suggestions?

      I never said the Calendar will appear for them, that's not possible. The cmdlet above simply makes any calendar invites sent to the group be forwarded to their personal mailboxes.
