Solution 1Recommended

Install the Latest Office Updates

Updating Outlook for Mac ensures you receive the latest bug fixes from Microsoft for Copilot formatting issues.

Microsoft frequently patches Copilot behavior through routine Office updates. It is highly advised to keep Microsoft AutoUpdate enabled rather than rolling back to older versions, as disabling AutoUpdate leaves your system vulnerable to security risks.

Open Help Menu

Launch Outlook for Mac and click on 'Help' in the top Apple menu bar.

Check for Updates

Select 'Check for Updates' to open the Microsoft AutoUpdate tool.

Install Available Updates

If a newer version of Outlook is available, click 'Update' and allow the process to finish before restarting the application.

Important Security Note: Do not uninstall Microsoft AutoUpdate as a workaround, as it prevents your Mac from receiving critical security and feature updates.

Solution 2

Report the Issue via In-App Feedback

Submitting a bug report helps Microsoft prioritize a permanent patch for the macOS 15.2 and Outlook 16.92 double-space bug.

Solution 3

Temporarily Disable Copilot in Outlook

If the extra spaces are severely disrupting your workflow, disabling Copilot acts as a temporary workaround until an update is released.

Frequently Asked Questions

Should I uninstall Microsoft AutoUpdate to fix the Copilot double-spacing issue?

No. While rolling back to an older version of Outlook without AutoUpdate is a known workaround, it is strongly discouraged. Removing AutoUpdate prevents your system from receiving important security patches and future feature updates.

Does this extra spacing bug affect all versions of Outlook?

This specific behavior has been widely reported by users on recent versions of Outlook for Mac (such as version 16.92) running on macOS (such as version 15.2). It appears to be isolated to the Mac client's integration with Copilot.

How can I quickly remove the double spaces from my email draft?

You can quickly clean up your draft using the Find and Replace tool. Press Command+F, type two spaces in the 'Find' field, and type a single space in the 'Replace' field. Click 'Replace All' to fix the document instantly.
