Mac
Scenario
Transferring an older version of Microsoft Office (2011) to a different Mac computer and attempting to activate it.

Solution 1Recommended

Locate the Original 25-Character Product Key

Understand the difference between a Product ID and a Product Key, and locate the correct key required for activation.

A Product ID is generated after installation to identify your specific software setup. It is not the same as a Product Key and cannot be used by Microsoft Support or any tool to reverse-engineer or retrieve your original activation key.

To activate Office 2011 on a new Mac, you must use the original 25-character alphanumeric Product Key provided at the time of purchase.

1
Check original physical packaging

If you purchased a physical copy of Office 2011, look for a yellow or orange sticker inside the DVD case. The key is formatted as XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

2
Search your email records

If you purchased a digital download online, search your email inbox for the original receipt from Microsoft or the third-party retailer to find the 25-character activation key.

Microsoft Support Limitations: Because Office 2011 reached its end of support lifecycle in 2017, Microsoft Support can no longer assist with recovering lost product keys for this version.

Frequently Asked Questions

Can Microsoft Support recover my Office 2011 product key using my Product ID?

No. A Product ID is only used to identify the software installation and cannot be used by Microsoft Support to generate, retrieve, or replace a lost 25-character Product Key.

Will Office 2011 run on a newer Mac computer?

No. Office 2011 is a 32-bit application. Apple removed all support for 32-bit applications starting with macOS Catalina (10.15). If your new Mac is running Catalina or a newer operating system, Office 2011 will not open.

Where can I normally find my Office 2011 for Mac product key?

The 25-character product key is typically located inside the original physical DVD case on a brightly colored sticker, or in the purchase confirmation email if you bought a digital download from an online retailer.
