I am reposting this thread. On both Stock and Touchdown Exchange Email, I have problems with only 2 exchange email users. On Stock, I cannot Reply, Forward, Reply All, to emails from a couple of my exchange server contacts/fellow employees. It just tries to do it (says loading) and then just reverts back to the original email screen. I've identified 2 contacts so far doing this and one is my Boss! I have just loaded Touchdown to see if that would fix it and it worse - won't open those emails at all. I hope someone can help.
