O365 Group email settings

I am in the middle of trying to create some automated routines that create groups in O365 and add/remove members from them as needed. One of things I ran into is that when an email is sent to the group, the emails are not going into each members' inbox and are only visible in Outlook through "Go to groups" in the left hand menu.

I can see the settings that need to be set but can't set them because either, A: it just doesn't do it or B: says I don't have permission.

Doing this through C# and the Graph SDK

The two items I think I need to turn on are below. What permissions are needed to be able to manage those settings but NOT be able to have access to anyone and everyones' email boxes, emails, etc or is there another way to do this?

 

IsSubscribedByMail

AutoSubscribeNewMembers

  • To update the AutoSubscribeNewMembers property via the Graph, you must use a separate request with just said property, see the note here: https://learn.microsoft.com/en-us/graph/api/group-update?view=graph-rest-1.0&tabs=http 

    Keep in mind that said setting does not apply retroactively to existing members of the group. For such, you need to manually adjust the "subscribers" list, which afaik is still only possible via PowerShell.

    The IsSubscribedByMail property cannot be set by the Graph API however, only via Exchange Online PowerShell at the Add-UnifiedGroupLinks cmdlet. Graph can only "read" said property.
