I had this same issue. If you are using the Active Sync iRule provided by F5 (well, it kinda sucks).

 

They are creating a persistence cookie (sort of) by hashing the IP address of the client. If you have users that are NAT'd to the same IP, they'll end up with crossed streams, and if ghostbusters taught us anything it was to never cross streams.

 

I'll go dig up what I did to fix this, assuming my assumptions are correct that you are using the stock active sync iRule.
