O365 add-ins disabled when COM add-in present

When certain large COM add-ins are installed on Outlook 2013 / 2016 for Windows. O365 add-ins get disabled and greyed out in email compose, but are still accessible if you write the email as a draft.

Is there a good explanation or solution for this behaviour? Are O365 add-in's not able to function normally when large COM add-ins are installed?

add-ins behavior is unpredictable when a COM plug-in is installed, because COM plug-ins can remove key item properties, change the ribbon or form entirely, etc. As a result, they are greyed out, as we didn't want the add-ins to load and behave unpredictably.
