Hi folks,
we have some weird issue with Eset Endpoint Antivirus v6.4.2014.2 and Outlook 2016.
Our environment:
Windows 7, 32 Bit
Office 365 Click-to-run
occurs in Outlook 2016 v1609 Build 7369.2055
occurs in Outlook 2016 v16.0.6965.2105
around 70 identical Clients deployed via Sysprep Image
We were using the ESET Antivirus 6 within our environment since June 2016 without any problem. Just pretty recently, since about 1 month, we are randomly experiencing crashes or freezes when sb. hits the "Send" Button in Outlook. This can occur while sending a standard email or even within an appointment request. The email itself is then stuck in the outbox, and the user has to restart outlook to get it send out. When Outlook freezes, there is no reaction of the program at all. When Outlook crashes, it just magically disappears.
Please note that we did not change anything with our Eset Version, but since we use Office 365 we are receiving and installing updates from Microsoft automatically. So it is quite possible that the Eset Addin causes some problems with the latest Outlook version which got deployed in the last few weeks.
The problem seems to disappear completely once we disable the Eset Addin (eplgOutlook.dll v6.4.2014.0) via GPO. Since the crashes happen randomly, it is quite difficult to pin it down. We have a small test group which reports positive results back to us once we disable the Addin, and negative results once we re-enable it.
So, my questions are:
Is anyone else experiencing similar problems? (Crash/Freeze while "sending" email)
Possible Workaround: Is the Eset Antivirus protection still active in Outlook even if we disable the Addin?
Thanks for your time.
