First Synchronization

After activating Email Archiving for a mailbox, the current inbox with all subfolders, including the sent folders (but without the recycle bin), is transferred to the archive via IMAP. This process may take some time depending on your mailbox size. You can check the archiving status directly in the archive:

Continuous Archiving

  • After the first archiving, every subsequent archiving takes place automatically every 5 minutes. It is currently technically not possible to synchronize more frequently. Emails that are deleted from the mailbox before synchronization are unfortunately not archived. We recommend that you do not delete incoming emails immediately. This ensures correct archiving.

    By default, archived emails are retained for 11 years from the date of receipt and then deleted.You can change the applicable retention policy at any time and specify a different retention period.You also have the option of retaining all archived emails for an unlimited period of time.Alternatively, you can create new retention policies to define individual retention periods for individual or multiple email mailboxes.
  • How to change an existing retention policy is explained in the following article: 

  • Edit Retention Policy

  • You can find instructions on how to create a new retention policy in the following article:

Note About POP3 Email Accounts

The POP3 email protocol was one of the first Internet protocols and is very limited in functionality. To put it simply, emails are first temporarily stored on the server until they are picked up by an email program. After the collection process, the emails are deleted from the server and are then only available on the recipient's computer, smartphone, or tablet.

Therefore, the POP protocol is not suitable for secure email archiving.

We therefore strongly recommend that you only activate email addresses for email archiving that are managed using the IMAP protocol.
