ISSUE
Currently there is no Report button for calendar items in classic Outlook. Common scenarios that you would use the Report button for calendar items include:
-
Report spam meeting items such as junk.
-
Report expected shared calendar invites as not junk.
STATUS: FIXED
The Outlook Team added support for M365 subscription to use the Report button on calendar items starting in the following builds:
Beta Channel - Version 2512 (Build 19524.15010) Current Channel Preview - Version 2512 (Build 19530.20000) Current Channel - Version 2512 (Build 19530.20000)
This change will advance to the other Office channels as they get build 19530.20000+. To find what channels have this build, please refer to Update history for Microsoft 365 Apps (listed by date).
