[SOLVED] We Are Preparing a Mailbox For The User (2024)

Ready for a mailbox makeover in Microsoft 365? We’ve got your back, and in the midst of it all, we are preparing a mailbox for the user.

So, picture this: I was in the tech jungle, facing a cloud mailbox issue in a hybrid setup. A user had the Exchange Online Plan 2 license, but the dreaded error kept popping up. Waited for days, tried a bunch of tricks, but nada. But, good news—I cracked the code, and I’m here to spill the beans on how I did it.

First up, I dove into the connect-msolservice module and gave the user account a thorough check-up. No errors lurking around, phew! A handy command to check for issues is:

(Get-MsolUser -UserPrincipalName user@techieberry.com).errors.ErrorDetail.objecterrors.errorrecord.ErrorDescription

No errors? Good vibes. I also double-checked for email address clashes—smooth sailing there.

Now, I threw the Redo-MsolProvisionUser command into the ring, but it didn’t do the trick. No worries, though—I had more tricks up my sleeve.

Time to dance with your Exchange Server! Hit up the “Exchange Management Shell” and pull off this nifty move:

Disable-RemoteMailbox test248 -Confirm:$false

Hold tight as the changes sync to the cloud. Once that’s done, head back to on-premises PowerShell and hit ’em with the magic wand:

Enable-Mailbox test248

Note: Should there be no Active Directory (AD) account in existence, the Enable-Mailbox command will be rendered ineffective.

Give it some time to sync (patience is a virtue, right?), then kick off the mailbox migration from on-premises to Exchange Online. Toss in the right license for good measure. Drumroll, please! The we are preparing a mailbox for the user error takes a bow.

Now, for the finishing touch, move those mailbox goodies from the soft-deleted one to the active one:

New-MailboxRestoreRequest -SourceMailbox “Soft Deleted Mailbox GUID” -TargetMailbox “Active Mailbox GUID” -AllowLegacyDNMismatch -BadItemLimit 100 -AcceptLargeDataLoss

Voila! Your data is safe and sound in the new digs.
