Office 365 -- Forward email copy from one GroupMailbox to another GroupMailbox?

    Question

  • Hello,

    we have a Headquarter group (GroupMailbox) and when an email is sent to this group we would like to also forward a copy to another group (GroupMailbox). How to forward a copy from one GroupMailbox to another GroupMailbox?

  • By GroupMailbox do you mean Office 365 Group?  Or do you mean a shared mailbox?

    If it's a shared (or regular) mailbox, you can simply configure one mailbox with an alternate recipient of the other.

    Set-Mailbox -Identity Mailbox1 -ForwardingAddress Mailbox2 -DeliverToMailboxAndForward $True

  • I mean those listed under get-unifiedgroup / Office 365 Group.

  • No, we cannot configure auto-forward on Office 365 Group.
    However, we can do it if it's a distribution group.

  • How would you forward an email sent to a ("Headquarter") GroupMailbox to another GroupMailbox? (A "Headquarter" group email is expected to forward emails to other relevant mailboxes.) Unfortunately it doesn't work using a SharedMailbox and trying to forward to a GroupMailbox.

  • Have you tried adding "another GroupMailbox" (you should really use the term "Office 365 group" since that's what it is and people will understand what you're asking when you use standard terminology) as a member of the "Headquarter" Office 365 Group?

    I don't see there being a "ForwardingAddress" mechanism for Office 365 groups like there is for mailboxes.

  • How can I add an another Office 365 group as a member to the "Headquarter" Office 365 group? I went to ECP -> recipients -> groups -> selected "Headquater" and choose Edit (https://outlook.office.com/ecp/UsersGroups/EditOffice365Group.aspx?id=a83***...***bf0), but unfortunately there's no option to add an another Office 365 group. It is possible to add a shared mailbox, but we use Microsoft Teams and groups. Having another Shared Mailbox would result in having two mail addresses, a mailbox@domain.com (GroupMailbox) and mailbox2@domain.com (SharedMailbox). How to solve this so that sending to hq@domain.com (GroupMailbox) forwards a copy of the email to mailbox@domain.com (GroupMailbox) ?

  • So apparently you can't do that.  Perhaps you'll want to use something other than Office 365 Groups for your task, such as a shared mailbox and/or distribution group.

  • Why does microsoft promote Groups if a simple forwarding is not possible.

    I tried forwarding from x to the "Headquarter" Office 365 Group (GroupMailbox) where x = :

    • Office 365 Group (can't do any forwarding at all)
    • Shared Mailbox (can't select a GroupMailbox)
    • Distribution List (can't select a GroupMailbox)

    So I can't forward to any Office 365 Group (GroupMailbox) as it looks?

  • I can't speak to Microsoft's marketing.  If Office 365 Groups don't work for you, use something else.

  • Victor, how do you apply that to forward from one Office 365 group to another Office 365 group?  That article describes how to forward to external recipients.

  • Ed, I did not do it myself but they suggest to create a distribution list that has an Office 365 group as a member. I think it will be possible to forward from one DL to another DL.

  • Victor, as mentioned in my prior post, an Office 365 Group can't be added to a distribution list (it doesn't appear in the search).

    SharePointer_, that's not true. You can do it via PowerShell  using Add-DistributionGroupMember commandlet. 

    Something like this:

    Add-DistributionGroupMember -Identity DGgroup1 -Member O365group1

  • Victor, I created a test distribution group, used Add-DistributionGroupMember and added that Office 365 Group to the distribution group, but when I send an email to the newly created distribution group, no email is delivered to that Office 365 Group. I can tell that the distribution group works because if I add a normal user (UserMailbox), that user receives the email, but unfortunately not that Office 365 Group.

    > Get-DistributionGroupMember hqverteil
    
    Name               RecipientType
    ----               -------------
    username     UserMailbox
    groupname_41bb7cae0a MailUniversalDistributionGroup

  • SharePointer_,

    I can confirm that doesn't work for me too.

    Well it seems we have to add an additional shared mailbox to forward:

    https://rickyraghavan.wordpress.com/2017/05/18/to-setup-forwarding-from-a-distribution-list-to-an-office-365-group/

    This ugly workaround works for me.

  • Victor,

    I can confirm that this works, thanks. Too bad Office 365 Groups don't offer this directly because now an email has to be sent through a distribution list email, which of course is different from our "Headquarter" email.
