Okay, now here we go:
Disable all shields for 10 minutes (right click on tray icon).
Check.
If same behaviour:
Boot in “Safe mode with networking” → Avast is not active in safe mode
Check.
I disabled it completely and resent an email and that didn’t’ fix it. :-\
I’ll have to reboot this afternoon or tomorrow into safe mode. Need to continue working (this is a work computer).
It’s got to be somewith the the exchange server??
I have one email account from a previous employee that it reads from the exchange server then my email is set up as pop3. I just now sent a picture to the old email account on the exchange server and it did the same thing. 
Any further thoughts on this issue?
