Restore full mailbox with Veeam Explorer for Exchange - ID handling

Question

If you want to restore a deleted Exchange mailbox (on-prem), you first have to create an empty mailbox within Exchange for the user. This has already been described earlier: https://forums.veeam.com/veeam-backup-replication-f2/restore-deleted-mailbox-with-veeam-explorer-for-exchange-t16174.html

Challenge is, while creating a new mailbox you also create a new ID for it. This leads to loosing some functionality (permissions to folders for 3rd parties etc., recurring appointments, etc.).

Is there another known way to recover the mailbox including its original ID?

I would rather have expected VEXE to create the mailbox for me while recovering - including all metadata.

With the Exchange Explorer you can only restore mailbox content but no Exchange metadata. While you could restore the Exchange AD attributes with the AD Explorer, I'm not sure if this would break something. What I would suggest, is to add the previous ExchangeLegacayDN to the new mailbox/user as a x500 address. Maybe this would solve the problems you've mentioned? If not, which ID are you referring to?

Hello@Michael Melter, I took a look at the forum link you shared and it seems to me that the process is still the same and thetarget mailboxmust be specified.Please see:https://helpcenter.veeam.com/docs/backup/explorers/specify_target_mailbox_onprem.html?ver=120When was this mailbox deleted? If the deletedmailbox retention periodhas not expired, maybe you should try this solution:https://learn.microsoft.com/en-us/exchange/recipients/disconnected-mailboxes/restore-deleted-mailboxes?view=exchserver-2019
