Since the new update in April, I have been unable to download my gmail to my outlook.  Now saying this there are times of day it will allow it and even last week it worked perfectly for a few days.  This week it has gone back to not allowing any sending or receiving of Gmail.  The error receiving (your server does not support connection encryption type) and sending (421 cannot connect to smtp server).
I have turned off avg to check that the issue is with avg and everything works perfectly.
I don't understand how this is not working when it has worked perfectly for so long.   Please help as its pretty pointless having an anti virus program that has to be turned off to use for emails.
