Solution 1Recommended

Isolate the App and Submit Diagnostic Feedback

Determine if the spacing issue is isolated to a specific app like Outlook or affects the entire Office suite, then report it directly to Microsoft developers.

Font spacing issues are often tied to specific application builds (such as version 16.54) conflicting with macOS rendering engines. Identifying the scope of the problem helps expedite a fix.

1
Check other Office applications

Open Microsoft Word, Excel, and Outlook to see if the font kerning issue persists across the entire suite or is isolated to a single app.

2
Verify sender formats in Outlook

If the issue is in Outlook, check emails from multiple different senders to ensure the abnormal spacing isn't caused by the sender's specific HTML or font formatting.

3
Submit feedback to developers

Open the affected Office application, click on 'Help' in the top Apple menu bar, and select 'Give Feedback' to submit a reproducible example and diagnostic data to Microsoft.

4
Seek community support

If the issue only happens in Outlook, visit the Microsoft Outlook Support Community and post your specific version details for dedicated assistance.

Reinstallation Warning: Simply reinstalling the applications usually does not resolve system-level font rendering bugs. Submitting feedback for an official patch is the recommended course of action.

Frequently Asked Questions

Why does my font spacing look weird in Outlook for Mac?

This usually happens due to font rendering conflicts after a macOS upgrade or an unresolved bug in specific Office versions (like 16.54). It can also be caused by the sender using a custom font that is not installed on your Mac.

Will reinstalling Microsoft Office fix the font kerning issues?

Reinstalling the application often does not resolve core font rendering bugs if the issue stems from an incompatibility between the current Office version and the latest macOS update. Waiting for a patch or submitting feedback is usually more effective.

How do I fix character spacing manually in a specific Word document on Mac?

If the issue is isolated to a single document rather than a system bug, select the affected text, go to 'Format' > 'Font', click the 'Advanced' tab, and adjust the 'Spacing' setting back to 'Normal'.
