We have various devices, iPhone, Evo, Droid X, My Touch 3g, Droid.... only the Evo works. (which happens to be my personal phone.)

One of the others gets the "server requires security features your phone does not support..." message - I tried changing the SSL settings, then the message doesn't pop up - it just fails. Right now, I have SSL turned off, and it still only works on the EVO.

Then I tried adding my account to another phone (my touch3g) and it worked.

So, it has something to do with the users.

I have added individual users to the Users sections, not groups. Removed users, reset, etc.

Any suggestions?
