Webex Meetings: Microsoft Outlook for Mac 16.23 and Later Incompatibility
Unsupported due to code change. A solution to fix this became available March 20, 2019.
Issue: Webex Meeting icon no longer works in Outlook on the Mac version 16.23 and higher.
You do need to delete from the Mac the old Webex Meeting application. Go to Finder, type in Application find Webex folder and click on uninstall Webex Meetings. Click restart when that is done then go download Webex Meetings application from .. (we are working on getting this download on our installation directions).
Select Webex Meeting and follow the installation steps.
When you get prompted to add your primary email, do so and follow the login prompts.
