Hey all,
Just installed Avast on a domain joined Windows 10 Enterprise x64 device but I've been unable to connect to Exchange in Outlook 2016 on a domain network after installing Avast Premier. I suspect it's to do with the man in the middle SSL cert. method Avast uses to scan SSL traffic.
I have tried the following:
- Modified Outlook.exe process to allow allow all ports, all IPs and all protocols to have in/out.
- In Web Shield I added both the internal and external exchange webmail IPs to the exclusions
- Disabled SSL scanning
- In Mail Shield I disabled Scan inbound mail, outbound mail.
- Disabled Mail Shield
- Uninstalled Spam filter
- Temporarily disabled all components
- Tried on Wi-Fi and Ethernet
- Removed Avast certificates but they get re-added on reboot.
It works when I connect to webmail outside my corporate network, only fails inside.
None of the above fixed the issue, the only way to fix the issue was to uninstall Avast.
Cheers,
Hynesy
