We have a couple of users with iPhone 4Ss that have been getting email fine up until about 4 or 5 days ago from our Exchange 2003 server.
Email is received fine on their desktops. However, the mail is not getting pushed to their iPhones. Not only is it not getting pushed, but when manually refreshing the email in the phone, it fails with either: "
Cannot get mail. The connection to the server failed
Cannot get mail. Server Error. Contact your server administrator
The error does not always appear. Sometimes it will act as though it has refreshed the mail, but nothing has come through.
Things I have tried:
- Deleting the accounts on the phones, resetting the phones, re-adding the accounts.
- Setup the accounts on a separate iPhone 4 and 3GS and still have the same problems. Other users are not experiencing any issues.
While the phones have plenty of free space and the Exchange accounts do not have a cap - I tried archiving (locally to pst) all of the users emails from the server. I then removed the account on the phones, reset and re-added the accounts.
This seems to provide a temporary fix, as email will start downloading again.
But it is only very temporary. By the next day it will have stopped working again with the same errors/symptoms.
I have gone over the server settings several times and everything looks correct.
I am stuck at this point. I cant keep archiving and deleting/re-adding accounts for these couple of users every few days. Mail has worked fine for them for over a year prior to this.
If anyone has any suggestions or ideas on things that I may have overlooked/should try, please let me know.
