Outlook 2016 crashes when using the Endpoint Protection Add-in

According to the Symantec site Microsoft has released KB4011570 to fix that issue. See link below.

Edward, the article states "the above patches do NOT apply to Click-to-Run installations" which we currently have.

I see you posted the same link. My apologies. Let me look further.

I was reading another article that said most Anti-Malware Solutions are not yet compatible with Click-to-Run installations and no further information is given. :(

The only other solutions I found was to disable Symantec in Outlook, which I assume you do not want to do.

I saw that also about disabling Symantec, we have other security components in place, but that's still not something we'd like to do.  Thanks

I figured that, and of course Symantec is saying to contact Microsoft for help which I am pretty sure has not helped.

I have used Symantec Endpoint with Office Click to Run, but no SEP add-ins. Attachments continue to be checked and otherwise Spam Filters keep the bad stuff out.

Hi Ron,

but that's still not something we'd like to do.

I respect your wanting to leave the add-in enabled, but may I ask why if it is currently causing you crashing issues and Symantec and Microsoft are playing the blame game on each other? Until they get their act together to resolve the problem, you do realize that Symantec Endpoint will still protect you (if it's able) when an infected file or email is accessed or opened?

To get a solution to this problem before Microsoft issues a patch, your only option may be to abandon the use of click to run and install a desktop copy of Office 365 instead.
