Change auto archive period and move archived e-mail to regular mailbox


Early 2022 the University of Twente has moved the UT-emailboxes to Microsoft Office 365. One of the consequences is that e-mail older than 2 year is automatically moved to the online archive. This manual describes how to change the auto archive period to "never", and how to move already archived e-mail back to the regular mailbox.


  • For this manual you must use the Microsoft Outlook 365 client on Windows.
  • This manual uses a consistent style of writing: references to text and buttons on screens are printed in italics, information that you have to enter yourself is printed in bold.  
  • Please note that moving a lot of e-mail can take a while.

Change the archive policy

  • Go to the tab Policy and select the time after which e-mail should be moved to the online archive at Move items to the Archive when older than.

You can restore the archive in two ways:

  1. Per Folder (This only works if no folder with the same name already exists.).
  2. Per content of folder (make sure the folder is already present before you "move").

Option 1 (per folder):

  • Right click on the folder you want to restore and select Move Folder.

  • Select the parent folder where the archive folder should be moved to and click OK.

Option 2 (per content of folder):

  • Select the archive folder whose contents should be restored.

  • Click on any e-mail in the folder and press control+a to select all mail in the folder. The selected items turn blue:

  • Right click on any selected e-mail and click: Move > Other folder...

  • Select the folder to move the e-mail to and click OK.
