When I "insert" an automatic signature after typing an email, the last few lines of the email are wiped out!
What causes that and how can I prevent it from happening?
Many users reported that they fixed their problems with emails being cut through profile creation. Save the emails you have on Outlook, and then remove the current profile. Restart the computer and then start Outlook and create a new profile, and your email should send correctly. More information can be found on the Microsoft forums.
