I mistakenly deleted users' mails using mailbox management. I want to restore Exchange DB to the time before the delete occurred, or to the time the backup was done (no redo logs replay).

How can I do that?

What is your setting for deleted message retention, and how long ago did you delete the messages?
Did you delete mail messages or mailboxes?

Ave you checked for disconnected mailboxes?

By default they won't get permanently deleted for 30 days.

How are you backing up your email?

Use suitable software to backup the information store.  Regulalry test recovery using recovery storage groups and restore from backup while the exchange is live and connected to the RSG.  That way you cannot accidentally overwrite the active DB.  Once restored to RSG, you can recover individual users mailbox.  Also good to know how to recover and its working without waiting for emergency.

However, as suggested you should reattach the deleted mailbox to the original user account first in which case you may not need to recover anything in this case.

If I delete the existing log files and make a restore, would that work?
I checked the server's smtp logs and only few email txns happened during this period.

If the message retention is 15 days then you can recover these.

But this is client based and will be a headache, I prefer restoring to the full backup I have.

If you only have a full backup and not the logs then restoring this backup will overwrite all your mailboxes.

The only other option is to use an RSG.  The client based option really is the easiest way to do this.

If you created an RSG, mounted it and restored from last backup, recover mailbox and the deleted items arent there, then they must have been deleted before backup and you will need to restore from the last backup prior to deletion.  Backup all current emails to PST before recovering from older backups and you can bring back the more recent ones from PST later.
