Can anyone help. I updated the May Critical updates on 15th May 2015 and then Outlook Stops, and in the Event Viewer for SChannel I get the following

I've no idea what 808 is, but the 40 is a handshake error.

Now if I go back to my restorepoint prior to the updates it all works again, until the system does the updates again (all 15 of them). It appears to be something in the updates, but cannot find other people complaining about this. It's also a bit disappointing that the error state of 808 seems to be undocumented.

Can anyone help?

I have since diagnosed which Patch it is with the problem. It's KB3061518 (MS15-55). Doesn't help much since bing/google aren't telling me about reports of problems with it (apart from a CAD package) running Outlook email workload.

Hi Kate,

Thank you VERY MUCH for your answer... I was struggling for several weeks until I found your answer... that worked also in my case even I was skeptical on your solution.

The strange thing was the fact I have 2 accounts on the same domain and on the same provider, both of them using IMAP over SSL. Just one of the account "died" suddenly on receiving messages but I did not realize the error retrieving message because I'm using 2 PC's and only on one using Windows 8.1 ceased working while on the same version of Outlook 2013 but on Windows 7 was working perfectly.

Even without restarting PC, immediately after adding the "Diffie-Hellman" subkey as you instructed, my Outlook 2013 started receiving messages, but still cannot undestand why the other account on the same outlook profile was working and just one of them was "dead".

Anyway - THANK YOU again! :)
