On June 16, Microsoft released an update for Outlook for Mac, with the latest build designated as version 16.110.2606.1317. However, users upgrading to this iteration discovered a severe glitch: when replying to or forwarding any electronic mail, the application completely omits the original message body. This anomaly is not a deliberate user interface modification but a functional error. Consequently, users are prevented from automatically appending historical text unless they manually copy and paste the original content.
Microsoft Confirms Bug and Proposes Workaround
Following widespread user reports, Microsoft published an official advisory confirming that replying to or forwarding an email does not include the original message in the email body in legacy Outlook for Mac. While the email subject line remains intact, the previous conversation history renders entirely blank. Microsoft is actively investigating the root cause of this regression. In the interim, the company recommends a temporary workaround: users can transition to the “New Outlook” interface. This modern style can be activated by clicking the Outlook menu or toggling the switch at the top of the Mac window, thereby unchecking the legacy mode. In this updated interface, replying and forwarding function normally with historical content preserved.
Rolling Back to Previous Stable Builds
Alternatively, affected individuals may consider rolling back to a previous build. Microsoft maintains an extensive update history of Office for Mac, providing standalone installation packages for older versions. For instance, the preceding stable build of Outlook for Mac is version 16.109.3 (26053122), which was released on June 2, 2026. Users seeking to downgrade their application to restore immediate functionality can utilize these repository links to stabilize their daily email workflows.
