Hi,

we are using MS Teams in our organisation. We have created multiple teams sites with an associated Microsoft 365 group. Now, the department lead would like to have one email address to communicate to all members of these teams groups.

however, i have not found a way to create a nested Microsoft 365 group. when i try to add the existing M365 groups as members, they are not provided in the search field.

what are our options here to create a nested group? I tried distribution lists and M365 groups, but both are not working.

    From what I have seen you can no nest groups into 365 Groups - even in powershell.
    It throws an error:

    he user couldn't be found for mailbox Identity:'XXXXXXXX isn't a mailbox user..

    Hi @Nicolas Pütz

    According to this link: Compare groups

    So it may not be possible to achieve this goal.

    In addition, based on my test, though it is possible to add Microsoft 365 Groups as members of a distribution list via EXO Powershell: 

    Add-DistributionGroupMember -Identity "DL" -Member "365 group"

    the message sent to the distribution list could not be delivered to the Microsoft 365 group mailbox or member mailboxes correctly.
