Inbox not sync anymore with exchange

dear expert

We are using Exchange 2010 and iPhone 5s.

One day one user informed me that his inbox is not syncing with Exchange. This is very weird.

I tired retart the mobile, delete the account and readded, nothing works. The very strange thing about this is, all users sub folder is there and perfectly synced... only Inbox is total blank. And It get a error message that said: Connection Failed... I mean this only apply to the inbox, other sub folders works fine...

Any idea what is the problem?

Thx

Can you move the mailbox to a new database on the server which will get rid of any corrupt items and will hopefully fix the problem.

What does OWA show? If the content is in OWA then the problem is elsewhere. You may well have to reset the iPhone if removing the account doesn't help.

That solution will be the last thing I will try, coz moving the whole mailbox to a new database will make the user unable to receive and send mail during that time.

Not on Exchange 2010. Moving the mailbox has no impact on the user until right at the end when they will have to restart Outlook. You can move mailboxes hot on Exchange 2010 to 2010 moves.

Is the iPhone on the latest iOS? The ActiveSync implementation on the iPhone is very poor and problems with it are well know.

Ok, Im moving the mailbox to a new database and see if this will work. 50% now and no corrupted messages... Im doubting if this is a mailbox corruption problem, i will see after it finishes.

You will not always get any corrupt messages reported, it is more like a reorganisation of the mailbox, so the data is indexed correctly.

Think of it like picking up a pile of papers from the floor, and sorting them as you put them back on your desk.

You might be able to do this without having to move it to a different server if it's just a corrupt message, and not a corrupt mailbox. Just create a new temporary folder, and move all the messages from the inbox into that folder (so the inbox is blank). And then send a message to that user (so there is only one new message in the inbox). If the iPhone still shows the error, then there is a problem with their mailbox on the Exchange server. But if the problem goes away, then you can either let the messages stay in that other folder, or you could start moving them back until you find which message was corrupt.
