If you want to archive multiple messages at one time, and no archive or retention policies are in place, use Outlook Web App to move the messages from your primary mailbox to the archive. See Retention and archive policies in Outlook Web App for instructions. Although admins set policies for the entire organization, you can override the policies to suit your needs.

Archive policies control how long messages are left in an email folder before they're moved to an archive retention policies control how long your messages will be saved. Best practices for moving your mail to the archiveĪlthough you can move individual messages from Outlook for Mac to your archive mailbox one by one (you can't move or copy multiple items at once), the more efficient way to make sure your messages get archived is to use Outlook Web App archive and retention policies.Īrchive and retention policies are set by your IT or Microsoft 365 administrator. Talk to your IT or Microsoft 365 admin about co-locating them. If your primary mailbox is in on Exchange Server, for example, and your archive account is in Exchange Online in Microsoft 365, you won't be able to use your online archive. Note: In order for your archive mailbox to work with Outlook for Mac both your archive and primary mailboxes must be either on an Exchange Server (on-premises) or on Exchange Online in Microsoft 365 (cloud).
