Office 365 June build (2606) crashes with Check Point Endpoint 89.10 and 89.21

[joesternna]

The users I support on the Microsoft Office 365 Current Release channel had a bad reaction to Office build 2606 and later. I had to roll back to 2605 to stop the constant crashing. Analyzing the memory dumps showed consistent issues with C:\Program Files (x86)\CheckPoint\Endpoint Security\EFR\cphnt64.dll. All office apps (PowerPoint, Excel, Word and Classic Outlook) were affected. 

I have a TAC case open but have not received any feedback since I submitted DMP files a few days ago. 

Microsoft's monthly channel is going to release 2606 very soon, so if you are running Endpoint you'll want to be ready.

I got the same issue with Endpoint version 89.25.5123

on the MS365 Version 2607 Build 20228.20124

There's a similar MS issue that is unrelated to Endpoint.

The problem is still occurring, even in version 89.25; I have users experiencing crashes and freezes in Outlook, Excel, and MS Project. It is ridiculous that it is taking this long to resolve the issue—if they don't fix this soon, I'll have to switch to another solution.
