Outlook for Mac enables users to back up their emails in a similar way to Windows, although the steps may vary due to the platform differences. The backup is saved as a .olm file, which can include emails, contacts, and calendar events.
You can backup your Outlook emails to your Mac computer in the following steps:
Open the Outlook application on your Mac.
Go to the top menu bar, click on Tools, and then choose Export.
- In the What do you want to export? section of the navigation pane, select Emails and click Continue.
Note: Outlook may ask you to choose a format. For most backups, the .olm format is recommended.
- Choose a location on your Mac to save the backup file.
- Click Finish to begin the export/backup process.
To enable AutoArchiving, stay in the File menu, select Options, and then click Advanced.
Method 2: Backup Outlook Emails to a Flash Drive/USB
Backing up your emails to an external device, such as a flash drive or an external hard drive, is a convenient way to store an offline copy of all your emails.
This is particularly useful when switching between computers or protecting against unexpected issues. The process of backing up Outlook emails to an external device on Mac is the same as backing up to other storage devices.
To back up your Outlook emails to an external device, follow the steps in How to Backup Outlook Emails on Your Mac and copy the .olm file to your external device for safekeeping.
