It sounds like you have implemented all the right checks - setting the proper timeouts is key here.
Regarding creating new session each time a user does manual activeSync - that should not be happening - if it really does, it would help to get a case open with F5 support and supply all the relevant data(debug logs from the APM as well as ssldump of the traffic that shows two separate manual activeSync connections). Also, it would help us to know which platforms/devices do you experience ActiveSync issues on, and what exactly do you classify as "manual" ActiveSync?

- blwavg_10621I was under the impression that every manual refresh was creating a new session. I have been testing this for a while and this does not appear to be the case. I do not know why though I have seen users with up to 20 sessions in a relatively short time frame. I guess I will have to look into those on a case by case basis.
- Michael_KoyfmanGlad to see that it does not appear to be the case - I've never seen this to be the case. You could have some users that have a ton of unique devices accessing Exchange.... pulling a report on those user ids and analyzing their UserAgent strings would help to find out what is really going on.
