Now, first of all, that password is to Exchange 2003
(only), right? You also have a (hopefully different) password to get into your account on Ubuntu.
Your Exchange 2003 password gets called for repeatedly because of time-outs on Exchange 2003: a security feature that can be a bother if you are continually (not continuous
ly) accessing Exchange 2003 during an extended Ubuntu session. When you close out of Evolution you will almost surely be re-asked for your Exchange password when you re-open Evolution.
So the problem can perhaps be reframed as:
- Would changing the timeouts (or another setting) on Exchange 2003 help you? You'd better have a very friendly SysAdmin if this is what you need.
- What is it that prevents you from feeling comfortable storing your Exchange 2003 password into your Evolution user set up?
Sometimes reframing the problem may give a key to its solution.
