iPhone only syncs one day of Exchange emails

Hi,

We have a couple of users in our organisation who are unable to sync any emails older than a day. The users need to be syncing at least a week.  If they set "mail days to sync" to 3 days or more, the iPhone email app gives the following error when syncing:

Cannot get mail - the connection to the server failed.

We are using Exchange 2003 SP2 but have tested on multiple iPhones (4, 5 and 6, all up-to-date). OWA/OMA is working fine, their email accounts sync on Android mobiles, but everybody else in the company is able to access emails on iPhones.

Any input will be greatly appreciated.

Thanks.

Have you tried wiping the phone and trying again? Also, have you tried to move the users mailbox to another database and see if this corrects the issue?

I tried wiping the phones already.

However, created a second store and moved the mailboxes to there and it syncs without issues now. Thanks!
