Installing older version of Evolution?

[Neil B. Cohen]

I have just installed FC5-Test2. I have to connect Evolution to an 
Exchange server, and it does not seem to be working well - loses the 
back end connection to Exchange at random (but frequently).

There is a note at startup that says that Evolution 2.5.x is not stable, 
and if necessary it should be removed and the older 2.4.x version 
installed. I was able to remove the program with yum, but I can't locate 
the older version  - how do I get it installed?

thanks,
