Observed behavior

Solution 1Recommended

Contact Your IT Administrator for Add-in Approvals

The most common reason for this error is organizational policies restricting software installations on Microsoft 365 accounts.

Enterprise and educational Microsoft 365 accounts often have strict Group Policies in place. These policies prevent users from installing third-party applications, including popular add-ins like Grammarly, to maintain network security and compliance.

1
Document the Error

Take a screenshot or note down the exact error message you receive when attempting to install Grammarly from the Microsoft Store or via the installer.

2
Reach Out to IT Support

Send a request to your organization's IT department or system administrator explaining that you need the Grammarly add-in for your daily writing tasks.

3
Request Account Permissions

Ask the administrator to approve, deploy, or enable the Grammarly add-in specifically for your Microsoft 365 account.

4
Verify Office Permissions

Have the administrator confirm that Office add-in installations are globally permitted under the current security policy for your user group.

Contact Your IT Administrator for Add-in Approvals
Enterprise Deployment: In many organizations, IT administrators prefer to deploy add-ins centrally via the Microsoft 365 admin center rather than allowing individual users to install them.

Frequently Asked Questions

Why is the 'Get Add-ins' button greyed out in Microsoft Word?

This typically occurs when your organization's IT administrator has disabled the use of the Office Store via Group Policy, or if your document is in Compatibility Mode. You must contact your IT department to re-enable access to the add-in store.

Can I install Grammarly for Word without admin rights?

The Microsoft Word add-in via the Office Store requires your Microsoft 365 account to have add-in permissions granted by your organization. If you try to install the desktop application version of Grammarly, you may also need local Windows or Mac administrator credentials depending on your machine's setup.

Does Grammarly support WPS Office?

Grammarly does not offer a specific add-in built for WPS Office. However, you can use 'Grammarly for Windows' or 'Grammarly for Mac'. These desktop applications run in the background and provide a floating widget to check your text in almost any desktop app, including WPS Writer.

How do I check if my Microsoft 365 account is managed by an organization?

Open Microsoft Word, go to 'File' > 'Account', and look under 'Product Information'. If you see 'Microsoft 365 Apps for enterprise' or a message stating 'Managed by your organization', your IT administrator controls your account and add-in permissions.
