Two of my users here at work have today had issues with all of their letters they type in outlook being Capital letters. The caps lock key is off and it makes no difference if they turn it on either. The letters also come out in caps if they hold the shift key down whilst they type (which if CAPS lock was on should make the letters lower case).
This only happens in the main body of the email, and if they change to any other program or even type in the to address box it comes out normally in lower case.
Any ideas what could be causing this?
