"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you repaired, defragmented and integrity checked your Exchange Database (with it dismounted)?

If not, then that's the first thing I would be doing after a server crash and the problems you are seeing.

Steps are:

eseutil /p (repair)

eseutil /d (defragment)

isinteg -s servername -fix -test alltests (integrity check)

The process will take about 1 hour per 4 to 6Gb (hardware dependant) and to defrag, you will need 110% of the store size in free disk space, otherwise it will fail.  You can use a switch to direct the temp file for the defrag command to a location where you do have the free space required if space is an issue.

alanhardisty, thank you for the suggestion...

However, the Exchange database is a new one created as part of the server rebuild. The info in the mailboxes was imported from backup pst files.

As stated... the info is in the mailboxes... just won't go to iphone.

If you think the processes you described will help I can give them a try. Can't do it till the week-end.

Some options for your reference:
1. Create a new exchange account and add some contacts and Calendar items, delete the exchange account from one of your iPhones, and add this new one.
2. Add some contacts and items from your iPhone and sync back to Exchange to see if works.
3. Back one iPhone with iTunes, and reset the device. I remember one of reset option only restore the settings of iP, will not remove apps, this was worked for me last time my exchange account totally stopped work.
4. Last thing you can do but more time-consumed, install a Windows Mobile simulator with ActiveSync enabled to check if possible to sync with Exchange. I always test ActiveSync with this simulator to ensure the functions of exchange.
