Exchange Mailbox restore behavior

[cstemaly]

If I restore a user's mailbox to two days ago, will it merge with existing items? Will emails received since the backup still be there or will they be overwritten?

Will it merge with existing items?

Yep. New items won’t be overwritten, they will be still present in the user mailbox.

Thanks.
