Allow Graph API access to Archive Mailbox (aka In-place Archive)
Microsoft's official documentation for Graph API access to Archive mailboxes is non-existent, and what people cobble together on public sites like StackOverflow is highly contradictory:
(some say it's impossible, some possible, but suggested solutions don't actually work).
- If it's possible to access Archive mailboxes (not just the regular archive folder in the normal mailbox!) via Graph API, document it properly.
- If it's not possible, make it possible.
