How to Fix Admin-Managed Add-Ins Not Loading in Word and Excel for Mac
Question details
Users are unable to load admin-managed add-ins in Word and Excel for macOS, encountering a 'Cannot connect to catalog' error despite the add-ins working on Windows and web versions.
- Product
- Microsoft Word and Excel
- Device & OS
- macOS
- Scenario
- Accessing company-deployed add-ins via the Microsoft 365 Admin Center within macOS desktop applications.
- Observed behavior
- The Admin Managed pane fails to connect to the catalog and displays an error message, preventing multiple users from utilizing required add-ins.
Ensure your Mac is connected to a stable network without aggressive firewalls, and verify that you are actively signed in to Microsoft Office with your designated work or school account.
Update Office for Mac and Enable Connected Experiences
Outdated Office builds or disabled privacy settings can block the connection to the admin-managed add-in catalog.
Microsoft frequently updates Office for Mac to resolve catalog synchronization bugs. Additionally, Microsoft 365 requires optional connected experiences to be active to fetch cloud-based add-ins.
Open Word or Excel on your Mac, click on 'Help' in the top menu bar, and select 'Check for Updates' to install the latest build.
Click on the user profile icon in the top left corner of the app to confirm you are signed in with the correct Microsoft 365 tenant account.
Go to 'Word' or 'Excel' > 'Preferences' > 'Privacy', and ensure the checkbox for optional connected experiences is checked. Restart the application afterward.
Verify Deployment in the Microsoft 365 Admin Center
The add-in must be explicitly configured to support macOS and assigned to the affected users within the admin portal.
Contact Microsoft Support for Tenant-Level Issues
If the issue persists across multiple Mac users with correct settings, there may be a backend service outage or tenant misconfiguration requiring Microsoft's intervention.
Looking for a Hassle-Free Office Suite for Mac?

Frequently Asked Questions
Why do admin-managed add-ins work on Windows but not on Mac?
macOS and Windows versions of Office handle add-in catalogs and background services differently. An add-in must explicitly support macOS architecture, and your Microsoft 365 tenant configuration must successfully sync with Microsoft's Mac-specific catalog servers.
What does the 'Cannot connect to catalog' error mean in Excel for Mac?
This error typically indicates that your Office for Mac application is unable to reach the Microsoft 365 Admin Center servers to retrieve the list of approved add-ins. This is usually caused by network blocks, disabled connected experiences, or a backend Microsoft service issue.
Should I downgrade my Office for Mac to fix add-in connection issues?
Downgrading is generally not recommended because older builds may lack important security patches and stability fixes. It is safer to keep your Office applications updated and escalate the issue to Microsoft Support for a permanent backend resolution.
