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 cases the mails are stored in old public folders.
It seems not to be that easy. Can Powershell be a solution? I appreciate any hint.

Basically you can't.
For some context, give a look to this thread: https://techcommunity.microsoft.com/t5/Change-Alerts/Site-Mailboxes-being-removed/m-p/43871#M658

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.

There are several threads discussing this issue. The problem stems from the fact that the shared mailbox that is connected to a Group behind the scenes is not surfaced as a standard mailbox, but it is rather used in order to implement a "conversation space" for the Group.
Hence currently there is neither an import and nor an export procedure.

Haven't personally tested it (yet), but QuadroTech's ADAM should support ingestion of PF items to O365 Groups: http://www.quadrotech-it.com/products/adam/

Yes, good find!
Not sure, though, that it can migrate also emails to Groups conversations...
Is that written clearly somewhere in the documentation?

Any feedback on the raised question from Salvatore until now or any other good way of solving the root issue?

Yup, the tool can migrate to Groups as well. Best contact them to get a demo or something.

Hot off the presses:
Use batch migration to migrate Exchange 2010 public folders to Office 365 Groups

Cheers, Brad. Do you (or anyone else) know whether this will work for migrating a O365 user's mailbox to the O365 group?
