Convert O365 Group to Shared MB
Please forgive my total lack of knowledge; I am not an IT professional.
You mention there is a way to move/copy messages from the Group to the Shared Mailbox using EWS? Is that Exchange Web Services? Could you elaborate any on how I might use EWS?
The closest I have come to was to using PowerShell along with "Get-Mailbox" and "Search-Mailbox" to try and move/copy messages but that didn't seem to work; not all the messages seemed to get copied.
I have also tried using the Outlook desktop client and dragging from the group conversations to the Shared MB and I keep getting a "permissions" error. I am the global admin so if I don't have permissions, it would seem that that is just not a supported feature?
Drag & drop for Groups is currently only supported in the webmail (OWA).
EWS is indeed Exchange Web Services, an API that you can use to perform item-level operations on mailboxes. Many of the third-party migration products use it, but it's a code solution, not something you can run with a few clicks in the browser.
Search-Mailbox unfortunately doesn't work against Group mailboxes. eDiscovery does however, so it might also be an option - run a search against the Group mailbox and export the results to PST file, then import them into the shared mailbox.
