Sign Out of Unused Installations via the Microsoft 365 Portal
Deactivate old Office installations directly from your Microsoft account settings to free up slots for new devices.
This is the most common method for users managing their own Microsoft 365 software installs. It allows you to revoke access to old devices without needing a system administrator.
Open your web browser and navigate to the official Microsoft 365 portal. Log in using your work, school, or personal account credentials.
Click on your profile picture in the top right corner and select 'View account'. Look for the 'Install and more' section, then select 'Apps & Devices'.
Review the list of devices currently connected to your account. Locate the obsolete or unused devices and click the 'Sign out' button next to them to free up your enrollment count.

Disconnect Obsolete Work or School Accounts in Windows
Remove old organizational profiles from your local Windows PC to clear residual device registrations.
Manage Devices via Intune Admin Center (Administrators Only)
IT administrators can manually delete unused device records or increase the organizational device enrollment limit.
Switch to WPS Office for Hassle-Free Document Management
If strict device enrollment limits in Microsoft 365 are interrupting your workflow, consider switching to WPS Office.

- 1. Download WPS Office: Visit the official WPS Office website and download the free installer for your operating system.
- 2. Install the software: Run the installer and follow the simple on-screen instructions to set up the suite on your device.
- 3. Open and edit files immediately: Launch WPS Office, sign in to your free account, and instantly open your existing Microsoft Office files.

Frequently Asked Questions
Why am I getting the DeviceCapReached error?
This error triggers when you attempt to register a new device but have already hit the maximum number of devices permitted by your Microsoft 365 subscription or your organization's Intune enrollment policies.
What if my Office account page lacks the option to manage installations?
If you do not see an option to manage or deactivate devices under your account settings, your licenses are likely strictly controlled by your organization's IT department or a software reseller. You must contact them to clear out the inactive devices.
Does removing an inactive device delete my personal files on that computer?
No. Removing or disconnecting a device from your Microsoft 365 account or Intune only revokes its access to enterprise applications and services. All personal files and local documents remain securely on the device's hard drive.
How many devices can I typically enroll under a Microsoft 365 subscription?
By default, standard Microsoft 365 plans allow a single user to install Office applications on up to 5 PCs or Macs, 5 tablets, and 5 smartphones simultaneously. Enterprise Intune limits vary based on the administrator's configuration.
