Renaming of O365 groups

Hi all,   I tried to search to see if anyone had already asked, but did not find any answers.   Today, I renamed one of my O365 Groups, but found the experience to be underwhelming: - No option ...

You are correct. When you rename the group from Groups UI it will only update the Group's display name and none other changed. So you can delete the group and create new one with the correct name. Please be aware that when you delete group using Power Shell it will not delete the hidden site collection. So it is recommended to delete it from Group UI.

Santhosh,

We have a group that was created and have decided to change it to a shared mailbox or back to a DL.  We need to be able to re-use the SMTP address associated with the Group.  What are your recommendations?

Is set-unifiedGroup -PrimarySMTPAddress suffice?

    hi, along with set-unifiedGroup -Identity <GroupName> -PrimarySMTPAddress <new email address>, you need to use set-unifiedGroup -Identity <GroupName> -EmailAddress SMTP:<newemailaddress> as this will remove the old email address from Office365 Group identity so you can reuse it.

      Hi,

       

      I used the command syntax

      set-unifiedGroup -Identity <GroupName> -EmailAddress SMTP:<newemailaddress>

      This is what my Attribute "EmailAddresses" looked before (slightly changed content):

      EmailAddresses : {SPO:SPO_0affa9c4-1111-2222-3333-162e4873a42e@SPO_89617050-2222-1111-3333-cb7206607595,
       smtp:TestingMSTeams@mydomain.onmicrosoft.com, SMTP:TestingMSTeams@domain.me}

      After running the command without failures, the attribute contents look same but the SPO: part is missing. Is this critical or can I proceed on using my Group without any problems now?

      After running the command:

      EmailAddresses : {smtp:TestingMSTeams@mydomain.onmicrosoft.com, smtp:TestingMSTeams@domain.me,
       SMTP:TestingMSTeams2@pia.me}

       

      Appreciate your feedback

        You would start with this command as noted above:
        Set-UnifiedGroup -Identity <GroupName> -PrimarySMTPAddress <NewEmailAddress>


        Then the correct command to remove the old address to free it up:
        Set-UnifiedGroup -Identity <GroupName> -EmailAddresses @{remove=”<NewEmailAddress>”}


        You can also rename the Alias:
        Set-UnifiedGroup -Identity <GroupName> -Alias <NewAlias>

        I'd imagine you could add your SPO record back with:
        Set-UnifiedGroup -Identity <GroupName> -EmailAddresses @{add=”<SPO:SPO_*>”}
        The SPO record has to do with SharePoint Online.

      This worked for the first group I tried, but the second and third came back with "We failed to update the unified group. Please try again later"

      Any ideas?

      Is it possible to use a distribution list as the primary SMTP? I can change the email in PowerShell to a new email but it will not let me change it to the address associated with a DL.
