Can't set up Outlook for Mac 2011 to use the archive mailbox feature in Exchange Online

Original KB number: 2830042


When you try to set up Microsoft Outlook for Mac 2011 to use the archive mailbox feature in Exchange Online for Microsoft 365, your attempt fails.


To work around this behavior, use Outlook Web App for mail, and apply retention policies in Exchange Online. Use the following settings when you apply the retention policies:

Tag name Tag type Retention age limit (days) Retention action
Personal 1-years move to archive Personal 365 Move to archive
Personal 5-years move to archive Personal 1825 Move to archive
*Personal never move to archive Personal No age limit Move to archive

*This tag is not enabled by default. Items that have this retention tag are either never moved or never deleted.

For more information about retention policies in Exchange Online, see Retention tags and retention policies.

Whereas Outlook for Mac 2011 doesn't support the archive feature, Outlook 2016 for Mac does support the archive feature. When you use Outlook 2016 for Mac, you can access your archive and move mail items into your archive.

More information

You can create an archive mailbox for a user's primary cloud-based mailbox. Users can use the archive mailbox (also known as a personal archive) to store historical messaging data by moving or copying messages from their primary mailbox to their archive mailbox. The archived messages reside in the cloud, and users can access the messages by using Outlook 2016 for Mac, Outlook 2013, Outlook 2010, or Outlook Web App.
