Export Outlook Data and Upgrade to Office 2021

Update Office 2011 to the final supported version to export your OLM file, upgrade your macOS, and then transition to Office 2021.

Because Office 2011 is a 32-bit application, it will not run on macOS Catalina (10.15) or later. It is crucial to perform the data export on your older macOS version before upgrading your system.

Update Office 2011 to version 14.7.7

Use the Microsoft AutoUpdate tool or manually download the Office for Mac 2011 version 14.7.7 security update to ensure the software runs correctly for the data extraction.

Export your Outlook OLM file

Open Outlook 2011, navigate to the File menu, and select Export. Choose the option to export your emails, contacts, and calendar as an Outlook for Mac Data File (.olm) and save it to a secure location.

Upgrade macOS and install Office 2021

Confirm your Mac meets the system requirements for Office 2021, upgrade your macOS via System Preferences, and then download and run the Office 2021 installer.

Import data into Outlook 2021

Launch Outlook 2021, select Import from the File menu, choose the 'Mac archive file (.olm)' option, and locate the file you previously exported to restore your data.
