F-Secure SAFE Banking Protection blocks Outlook access to Office 365 Exchange
Does anyone have an solution for this problem. We are a small office with 10 SAFE licenses assigned to a mix of Mac and PC devices. The PCs are currently running Windows 7 and Office 2016 (from the Office 365 download) with SAFE 17.0 - not been prompted about the 17.1 update yet. The Macs run Sierra or High Sierra and Office 2016 with SAFE version 17.1.
On the PCs. With Banking Protection enabled the Outlook client shows a 'not synchronised with Exchange' error a few minutes after the user opens a banking site. If you close the Banking Protection via the drop-down window at the top of the screen Outlook will find the Exchange server again and everything is normal. I'm not sure that closing the Protection is the expectedrecommended response, but this is also a repetitive task that the user doesn't want.
I have ticked the checkbox that says 'keep my current Internet connections open' in the Banking Protection setup but this DOESN'T have any positive effect on the problem - probably because Outlook is a client that polls the server and I suspect that the polling creates a new TCP session every time it happens, so technically it is not an existing session that the checkbox is supposed to handle.
In fact the checkbox does work correctly because without it ticked my remote support access to the PCs fails if the user has a banking site open in the browser.
You will appreciate that knocking-out Outlook is not an ideal modus-operandi, so to get around the problem we have turned-off Banking Protection - the lessor of the not ideal solutions.
I have never seen the problem on my Mac running Sierra and now High Sierra and I have Banking Protection enabled.
Any ideas? Other than turn off Banking Protection on the PCs.
Thanks in advance.
