A better way to recover a mailbox

Unfortunately this change stepped on a an important process for our Hybrid environment. We use Get-RemovedMailbox and New-Mailbox -RemovedMailbox in order to mimic the on-prem behavior of reattaching a disconnected mailbox to another user. We sometimes

have identity provisioning conflicts and other issues arise where this function is invaluable. Having to merge mailboxes rather than just reattaching them is less desirable in these cases. Does the exchange online team have any plans to allow a soft deleted

mailbox to just be 'attached' to another user rather than merged? Either that or return some similar functionality like Get-RemovedMailbox? How are we to deal with mailboxes that are removed after a Remove-MSOLUser -RemoveFromReycleBin?

Is this commandlet available to all the tenants in Office 365?

New-MailboxRestoreRequest : The term 'New-MailboxRestoreRequest' is not recognized as the name of a cmdlet, function. I am a global admin with Organization Management permission.

Why is my question being filtered? Is that so scary for you to approve

Thanks Tim, good article.

You can utilize inbuilt utility to repair Exchange EDB file. But inbuilt utility can only be work in minor corruption. If your Exchange EDB file is highly corrupted then you have to utilize a third party tool "Exchange EDB Repair Software" can easily repair

your corrupted, damaged, deleted, inaccessible etc EDB files. Try its DEMO Version from here: -

Thanks for the information, but what is the solution when the mailbox is hard deleted and Get-RemovedMailbox is disabled?

Is this New-MailboxRestoreRequest going to perform the proper write-backs to the on-premises MailUser object and correctly tag it as a RemoteMailboxUser, or do we still need to run Enable-RemoteMailbox ourselves?

This is great! One issue that often occurs as part of accidental deletions is that NDRs start to surface because other users have the deleted users legacyExchangeDN address in their Outlook NK2 file, so sending with autocomplete attempts a delivery to

the non-existing recipient. Would be great to see documented guidelines on that as well as part of this updated approach. Thanks!
