Why does a user have access to a Shared Mailbox
The 'usual way' of giving someone access to a Shared Mailbox in Office365, is to add them to the list of 'Members'. Now, I have a user who has access to a shared mailbox, which is fine, but I can...
The most likely way is your last hunch of it being logged directly into, since you can still technically log into a shared mailbox as long as the account is not disabled.
Thanks for your suggestions!
I have monitored the situation over the past week because I saw conflicting information. Turns out this mailbox effectively jumps between being a licenced and unlicenced (e.g. shared) mailbox. When I look now, Office365 admin center shows it in the "Active users (licenced)" list (Essentials), but Exchange admin center does not include it under "mailboxes". Both Office365 admin and Exchange admin do show it (also) under 'shared' mailboxes. We can agree this is weird, right? 🤔
I'm thinking perhaps I can explicitly "convert it to shared mailbox", and then explicitly convert it back to "licenced account". Hopefully that will stick.
