Backup: How can I restore deleted emails?

Have you accidentally deleted emails or folders? Can the deleted data also no longer be found in another folder or in deleted items?

If so, we can try to restore the emails from a backup. This is possible if certain conditions are met. In this help article, you can learn which conditions these are, how you can request a backup of data and how it will occur if applicable.



  1. The accidental deletion of emails must have occurred no longer than a week ago. Security backups of your data are saved for 7 days – and then deleted.
  2. The crypto mail storage feature must not have been activated at the time the emails were deleted.
  3. The deleted email data must have still been located in your mailbox at the time when at least one of these backups were made. We typically make a backup of your data once every 24 hours.

How to have a backup restored

If the conditions are met, next log in to your Posteo account. After logging in, follow these steps:

  1. Open Settings.
  2. Click on My account.
  3. Open the menu item Restore emails.
  4. Enter the date and time when the deleted email was still available.
  5. Click on Submit.

That’s it! You have requested to restore a backup of your data.

Processing your request may take anywhere from a few hours to a business day. We will try to restore a matching backup for you. You will receive an email once the process has been completed.

How to open the restored emails

As soon as we have restored a security backup for you, you will find a folder with the name BACKUPRESTORE in your account. The folder contains a complete copy of all the emails and folders in your mailbox at the time of the backup. To open the restored emails, follow these steps:

  1. Click on the arrow underneath the folder symbol to display the restored folders.
  2. Click on the desired folder to display the emails.

You can now move the necessary email(s) into another folder. You can learn how to move a whole folder here. Afterwards, you can delete folders that you no longer need.

Tips & troubleshooting

I deactivated crypto mail storage after accidentally deleting emails. Are you now able to restore my deleted email data for me?

No. Backups that were created before crypto mail storage was deactivated will remain encrypted.

The email I’m looking for is not contained in the backup. Why?

At the time you designated in your request, the email was not part of the backup.
