iPhone cannot connect to Exchange 2003

Have you tried checking the users account by logging into Exchange over the web?

I can login over the web no problem.

Give the proper domain name. say if it is abc.com don't just give abc.

still does not work. Verifies ok when creating the account but cannot connect when accessing emails. I think its something on the server.

Check the server application logs where Active Sync is running, try IISReset on that server and try again.

Try this one

What you need to do is keep trying to connect after it say 'unable to verify'. Then after a few attempts you will have the option to save the details, then you will get a warning saying, 'you may not be able to recieve mail'. It's okay, you will be able to, it's a certificate problem. Just browse to the folders (sent, inbox, delete etc..) and it will bring down your mail.

Thanks :)

The following thread suggests you might have a corrupt mailbox on your hands:

My regular fix for that would be to dismount the store and run:

eseutil /p

eseutil /d

isinteg -s servername -fix -test alltests

Then that should repair, defragment and integrity check the mailstore and should get Activesync working (hopefully).

Failing that - please work through my article linked above.

You can also, create a new mailbox for this user, import the data to new mailbox. Remove the old mailbox and assign the old Email address, also add the old legacy exchange dn value, so Outlook user with cache mode enabled shouldn't get any bounce back.

Excellent article. Repairing the databases solved the problem. Following the article I tweaked the configuration on IIS and it now works perfectly.
