Shared Mailbox Recovery

[Mike Hammett]

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.

Hi MIke,

To get support from Microsoft you can go in the M365 admin portal to the support menu - New service request
On the right a menu slides out
Type you issue in the search bar followed by enter
at the bottom of the menu you have the option to contact support

Hope this helps

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.

That's disappointing.of your partner, but as far as I know is that despite you have bought it from you partner and you are a global administrator you should be able to make a request.
Maybe this can help you.

Ah, because I have purchased it via a reseller, Microsoft support will no longer help me directly.

One's reseller needs to escalate it to Microsoft or one needs to drop the reseller.
