We recently built an exchange 2010 server and migrated mailboxes from an Exchange 2003 server. We are on RU4 and running server 2008 enterprise edition 64 bit. It is a virtual machine with plenty of resources for its load (8 CPU's and 32GB RAM, currently hosting about 350 mailboxes. Most mailboxes are under 150MB)
Everything on the server seems to be working properly, we have several users that connect android based phones to sync their mail, calendar, and contacts.
We have several users operating on Motorola i1 android phones on the Nextel network. One user in particular has his email ap on the phone "crash" every couple of minutes bringing up the "force close" or "wait" options. We have tried configuring his mail profile on another phone of the same model/version and experienced the same problem. We then configured a different users mail profile on the phone and it worked fine, so we have ruled out the phone, and service as being a problem.
Oddly, this users mail profile works on other phone models such as the Verizon DROID and also worked when the Touchdown ap was installed on the Motorola i1, however neither of these solutions work as he needs the Nextel push-to-talk functionality on the phone, and Touchdown is not compatible with this.
On the exchange server, I attempted to perform a local move request with a destination target of another database on the same server. I have tried this several times over the past week and I have only got it to actually move on one attempt, it took 1 hour and 47 minutes to move and reported 0 "bad items". Other times i have waited over 3 hours and it hangs at 20% completion. The mailbox is just under 300MB, so should take no longer than 10 - 15 minutes to move. All other mailboxes can be moved without a problem.
The problem with the phone persisted after the one successful mailbox move. Due to the problem with the mailbox move hanging I believe there is some type of corruption or problem with the mailbox, and the application used by the Motorola i1 does not perform error handling as well as other applications and phone models that do not present this problem. Is there any type of utility I can use to check the mailbox for problems?
