The latest update for Office 365 (Version 2404 Build 17531.20140 Click-to-Run) will break your Office Apps (Outlook, Word, Excel etc) if CM Addins are enabled.
If you try to open an Office App with the CM Addin enabled, it will crash.
Please avoid the Office update if possible for now. Alternatively, disabling the CM Addins will allow the Office Apps to open correctly.
OpenText have been made aware of the issue.
