Sign Out of Office on Unused Devices via Microsoft Account
Manually remove devices you no longer use from your Microsoft account to free up activation slots for your new computer.
Microsoft 365 limits the number of devices you can be simultaneously signed into (typically 5 devices per user). Because this limit cannot be increased, the only way to activate Office on a new device is to sign out of an older or unused one.
Open a web browser, go to account.microsoft.com, and sign in using your Microsoft 365 email and password.
Click on 'Devices' on the top navigation bar or the dashboard to view a list of all hardware currently linked to your account.
Locate the computers or mobile devices you no longer use, select 'Manage' or 'Info & support', and click 'Sign out' or 'Remove device'.
Restart the Office application on your new device and attempt to sign in again. The activation should now proceed successfully.

Frequently Asked Questions
What is the exact device limit for a Microsoft 365 subscription?
With Microsoft 365 Personal and Family plans, you can install the Office apps on all your devices, but you can only remain signed in to 5 devices simultaneously per user.
How long does it take for a removed device to free up an activation slot?
Once you sign out of or remove a device via your Microsoft account dashboard, the activation slot is usually freed up immediately, allowing you to sign in on a new device right away.
Can an IT administrator increase the device limit for enterprise users?
No, the standard limit of 5 simultaneous sign-ins applies to enterprise licenses as well. Admins cannot increase this hard cap but can centrally revoke access from inactive devices through the Microsoft 365 admin center.
