Microsoft 365 Backup - Exchange Restore, recovery folder is not available

Kidd_Ip Thanks for the hint. The only option is the remark about missing changes in an Exchange mailbox. 

If there are no differences between the current state of a mailbox and the prior point in time from which you're attempting a restore, there will be no restore performed and no new folders created when a “restore to a new location” request is made. We don't plan to modify this behavior in the future.

Unfortunately, the restore state is very limited and says nothing about whether there were changes or not. Just that the restore is completed. A bit of a black box. 

Btw, some minutes ago I tested the same steps from the past two days again, and now the folders from the recent restores are visible. Seems it's really an early preview. Found some issues with SharePoint restores too. 

Kidd_Ip - You can't specify the name of the restore folder for exchange. Per the documentation

The destination of restored items can be chosen from two options, then select Next.

Restore to a new folder where the content will be restored to a newly created folder named Restored Items YYYY-DD-MM, HH:MM.

If you don't see a restore folder, it is possible there were no changes from the restored point in time and the current state. In that case, nothing is restored.
