I would suggest have him reset his phone and set up the synchronization again. 
He likely doesn't know what's going on.

We've had several iPhones for a few years. I did find a user account that was 
kicking an ActiveSync error every now and again (pretty sure he's a DroidX 
user). When I disable that user's mobile options everything seems to return to 
normal. My average writes/sec right now are ~4 with a max of 400. I guess I 
didn't realize that ActiveSync events created the trans logs in Exchange.

I guess I'm just at a loss for what a user can be doing on their smartphone 
that it does this when we've got a couple dozen other Droid + iPhone users that 
can't produce the same problem.

List,

Wanted to see if I could enlist your help to at least point me in the right 
direction on an issue we're having with our Exchange 2003 server running on 
Windows Server 2003. This primarily has to do with our disks which are two 
separate hardware RAIDs. One RAID is broken up into two logical drives - C: for 
system files and F: for Exchange transaction logs. The other RAID is one 
logical drive D: which houses all of our Exchange databases. Our last complete 
backup completed yesterday at around 7:00am and since then we have noticed 
three things occurring:

1. The server is generating an inordinately high amount of transaction logs for 
our organization at almost 40GB - a normal day for us can produce ~4GB.
2. The number of disk writes is also abnormally high. Using perfmon I've 
observed the writes/sec at an average of over 1,000 and highs of over 5,500.
3. Event ID 602 appeared in our event viewer. This event basically tells us to 
perform an offline defragmentation of the databases.

We have four mailbox stores that range in size (107GB, 57GB, 12GB, and 10GB). 
I've scheduled a maintenance window for this weekend to perform the offline 
defrag as recommended by the event error.

The only thing that we've done recently is that a couple of weeks ago we 
deleted a number of mailboxes (~50) as part of a measure to stay under our GFI 
MailArchiver license count. None of the mailboxes were particularly large.

I wanted to find out if anyone else had experienced anything like this before 
or if anyone had run into Event ID 602 before. Any help, even to point me in 
the right direction would be much appreciated. Many thanks in advance.
