How can I export OST or Archive on a Mac?


  1. With Microsoft Outlook open, choose File
  2. Choose Export from the menu bar
  3. Check all boxes and click continue
  4. Choose a location to store your Outlook for Mac Archive

If you have a significant amount of email or calendar events, this backup can take upwards of ten minutes. You will be unable to use Outlook during the backup. Please do not interrupt the process. The file it creates may be larger than 1GB in size. Our test case created a 2.68GB file and it took roughly ten minutes to complete. Your results may vary.
