We are getting emails after few hours delay, we are having problems to send new email (it is sent but does not save in "sent" folder). Always having "connection time with server exceeded". We have change nothing in our company. Servers, antivirus scans are the same. Everything started after auto update to 78.12

What's the antivirus and its mail settings? When TB updates, it can become incompatible with the existing antivirus app, unless that app is set to exclude the TB profile folder and scanning of secure connections is disabled. If you are in fact experiencing crashes, post your Crash IDs from Help/Troubleshooting.
