BlackBerry® Enterprise Solution

Outlook shows 17 unread E-mails whilst my blackberry shows 974 unread emails.

I am still receiving new emails and when I delete an email off of my Blackberry it shows up as read on my Outlook.

I have tried resending my service books which made no difference. I have tried fiddling around with the reconciliation settings and this made no difference.

I have restarted the server and restarted the phones which has also made no difference. There are several users having problems with their blackberry is there a reason for this?

I have also changed the messages state size to 1000 and it cured 99% of our issues.
The performance hit and RAM increase is almost nil on the BES box.

On Device also double check:

Make sure that Wireless Reconcile is set to On. Sometimes toggling that to off, saving it, then turning it back on.
Messages Options - Email reconciliation -
Delete on Mailbox and handheld,
wireless reconcile = Yes
On conflicts = Mailbox wins.

If still not working and you moved a user mailbox.
