I have engaged our reseller via support ticket, but they haven't been overly useful. I cannot find the ability to enter a ticket directly to Microsoft via either my Office 365 admin portal or the Partner Center.
About a week ago, Microsoft lost a bunch of our Shared Mailboxes. I’m trying to figure out how to get them back, but it’s a long, undocumented road.
I found the real -> shared mailboxes with `Get-Mailbox -SoftDeletedMailbox`, but not the boxes that were originally created as shared.
I was able to restore the ones I did find via `Undo-SoftDeletedMailbox allieb@contoso.com` but that doesn't work for the other boxes. It also doesn't seem to actually produce a usable mailbox.
They do not appear in active or deleted mailboxes.
Not all shared mailboxes disappeared, just some of them.
For one of the mailboxes, a message trace shows mail coming in until some time on the 12th. The admin audit log shows no activity on the 12th.

I have tried that, but there's nothing there (anymore) about contacting Microsoft, only the thus far useless partner I purchased Office 365 from.
I know it used to have something as I can view a prior service request that I had with Microsoft. I just can't enter a new one.
