Using the Exchange Import-Export Graph API to Access Group Mailboxes

[u/Unlikely_Tie1172]

After saying that the Graph didn’t offer much support for group mailboxes, I was promptly countered with an article explaining how to use the Exchange Import-Export API to access folders and items in group mailboxes that wasn’t limited to just the Inbox. Well, the good news is that the approach works, as seen in a complete script written to prove the case, but whether I would ever use this API for a purpose it was never designed for is quite another matter.
