Sorry, I wasn't clear enough. I'm talking about the sync cache and/or  
client state. These are not related to any other Horde cache. They are  
stored in SQL.

Anyway, if removing the client from Horde's activesync administration  
screen doesn't force OL to reset itself, you can either remove OL's  
local cache file and/or just delete and recreate the account in OL.
