Restoring Exchange Online mailbox to another tenant

Post by dirkdigs »

consider the following scenario
user exists in tenant A
users is moving to tenant B


I have backed up the mailbox in tenant A
I have created the user in tenant B

How easy is it to restore the mailbox data to the user in tenant B now?
Is it simply a matter of adding both Orgs into VBO365 and selected tenant B during restore?
Does anything need to match up? proxy address or anything similar?

for example if tenant A is authoritative for 4 domains total and i have only added a single domain to tenant B will the mailbox still restore without errors?

Veeam Backup Office 365 will only restore data.
It will not restore metadata (Mail Addresses, Tenant Configurations)

- You have to create the mailbox by yourself in the target Tennant. Then give the backup agent which you are using to add the tenant full access to the new mailbox and restore the data.

I have given you a guide in your topic a few days ago ;)

You cannot choose a target Mailbox with GUI Restore, if you are doing a multiple Mailbox Restore. It has to be the original mailbox.

You can try the powershell method to automate the procedure. Loop through all Mailboxes, filter the Items with a date query (from your other topic) and pipe the output to the next command to start the restore.

I don‘t have a script, but I think it should be possible with reading the guide and the examples to create s own script for your scenario.
