Solution 1Recommended

Check Organizational Restrictions and Admin Policies

Determine if your school or workplace IT administrator has blocked the installation of third-party add-ins from the Microsoft Store.

If your Mac or your Microsoft 365 account is managed by an organization (like an employer or a school), administrators often restrict software installations for security reasons. This policy will block all add-ins, including Grammarly and Adobe, from being added to Word.

1
Identify account type

Check if you are signed into Microsoft Word using a personal account or an organizational account (Work or School).

2
Contact IT support

Reach out to your organization's IT administrator and ask if they have restricted Microsoft Store access or Office add-in installations.

3
Request specific access

If restricted, request the IT department to whitelist or deploy the specific add-ins (like Grammarly) directly to your managed Microsoft 365 account.

Check Organizational Restrictions and Admin Policies
Managed Devices: Even if you use a personal Microsoft account, a Mac provided and managed by your workplace may have system-level profiles installed that block third-party software integrations.

Frequently Asked Questions

Why did Grammarly suddenly disappear from my Word for Mac?

Grammarly may disappear due to a recent Word or macOS update, a background change in your organization's IT policies, or a temporary glitch. You can check the 'My Add-ins' section under the 'Insert' tab to see if it just needs to be re-enabled.

How do I access the Microsoft Store within Word for Mac?

To access the store, open a document in Word for Mac, click on the 'Insert' tab on the ribbon, and select 'Get Add-ins' or 'Store'. This will open a window where you can search for and install new tools.

Can I bypass my organization's add-in restrictions?

No, if your Microsoft 365 account or Mac device is managed by your school or employer, administrative policies override personal settings. You must contact your IT department to request permission or ask them to deploy the add-in for you.

Does this add-in issue only affect Microsoft 365 subscriptions?

While commonly reported by Microsoft 365 users, standalone license versions of Word for Mac (like Office 2021) can also experience add-in installation issues if the software is outdated or restricted by local system settings.
