Solution 1Recommended

Sign Out of Unused Office Installations Manually

Since Mac devices do not appear in the Microsoft account device list, you must manually sign out of Office on your other computers to free up activations.

Microsoft 365 allows simultaneous activation on up to 5 devices. However, macOS devices currently do not display in the Microsoft account device portal. If you hit the limit, the system is likely counting hidden Mac activations or old PCs.

1
Access your Microsoft account

Open a web browser, navigate to the Microsoft Account portal, and sign in with your Microsoft 365 credentials.

2
Sign out of listed PCs

Go to the 'Services & subscriptions' tab, locate your Microsoft 365 subscription, and click on 'Manage'. Look for the 'Installs' or 'Devices' section to sign out of any unused Windows PCs.

3
Sign out of other Macs directly

For other Mac computers you own, open Microsoft Word on those specific Macs, click the 'Word' menu in the top left, and select 'Sign Out'.

4
Restart and activate

Restart your current Mac, open Word, and attempt to activate the software again.

Frequently Asked Questions

Why doesn't my Mac show up in my Microsoft account devices?

Microsoft's account portal currently only displays Windows PCs and Xbox consoles. macOS devices do not populate in this list, even though they still count toward your 5-device Microsoft 365 activation limit.

How many devices can I activate Microsoft 365 on?

You can install Microsoft 365 on all your devices, but you can only be signed in and actively using Office apps on a maximum of 5 devices simultaneously.

What happens if I exceed the Microsoft 365 device limit?

If you exceed the concurrent limit, Office will prompt a 'Maximum Device Limit Reached' error, and your apps will enter reduced functionality mode, preventing you from editing, saving documents, or using premium templates.
