How do I migrate old mails from PST file or public folder into a Group?

I have to migrate several old projects into (new) Office Groups. One of the tasks is to 'import' (lots of) old mails for reference. Sometimes I have old (and shared) PST files as source. In other cas...

You can't sounds to extreme to me :-)...I would say there is nothing in the box for your scenario and problably third party tools won't help here too...my understanding is that the Microsoft Gaph should be the medium to do this migration, but I don't have an idea about how to do it

    Juan, if I understand well, Robert wants to import (lots of) old mails into the mailboxes associated with Groups.

    As we have discussed in the thread I referenced, this is not supported at the moment.

    Apart from forwarding every single mail to the Group email address, the only workaround appears to be to leverage an unsupported "hole" in the system and do a lot of drag and drop by means of OWA, which, I think, is a little troublesome.

    Since this is a very frequently requested feature, I really hope that one day you can come out with one of your scripts to solve the problem. ;-)

    But, in the meanwhile, IMO the answer to Robert is: "you can't".

      What do you mean? Is there a unsupported way?

        Yes. The unsupported and undocumented workaround is described in the thread I referenced above.

        Basically you add the Group mailbox as a shared mailbox in OWA and then you can drag and drop mails from other folders to the Group mailbox.
