Hi Experts,

I am having a really weird problem which is puzzling me.

One of our customers has a Exchange 2003 server (SP2) running on Windows Server 2003 (SP2). I enabled Mobile sync, configured his IIS with a valid certificate en made everything working on one of their Nokia E71 phones.
After a few days this user tells me about having differences in his mobile calendar and his Outlook calendar.

I did several tests and this is what I know for sure:
- Calendar items created within Outlook Web Access get successfully synced back to the phone.
- Calendar items created on the phone get successfully synced back to both Outlook 2003 and 2007.
- Calendar items created within Outlook 2003 or 2007 does show up within Web Access or OMA (Mobile Access) web page but don't get synced back to the phone.
- When an item created by Outlook is changed through Web Access or OMA, the item will successfully get synced back to the phone.
- Nokia Mail for Exchange log tells me no differences where found in calendar.
- Problems also persist on an Apple iPhone so i'm thinking Exchange is the cause here.

I allready deleted and reinstalled alle the Exchange Virtual Directories within IIS but the problem still persists.

I hope someone can help me with this issue.



Best regards,

Koos

I have something to add to this puzzling situation...

I took another Nokia E-series phone and configured it as well for the same server. I created a new mailbox for myself so I could monitor and troubleshoot remotely on this phone without going to customers location back and forth.

On this new account, on this new phone the same problems occur but it gets even weirder. Some e-mails I sent out to myself on this server, show up in Outlook en Web Access but don't show up on the phone. The phone tells me there were no changes and synchronisation was succesful. To make things really complicated all the appointments I made earlier in Outlook (wich didn't showed up on the phone) suddenly appeared on the phone's calendar! I immediately made some more appointments through Outlook but they would not synchronise. Maybe those will show up tomorrow as wel??

I'm not sure which component in Exchange talks to the phone and tell it that there were changes or not. It seems that that's the problem at the moment.

This is a bug. I need to sync my E71 several times to get everything equal on both sides.

Unfortunately I synced manually several times but no new items will be added.

I noticed that if I wait until the next the all items from the previous day will be added but all newly created items will have to wait until the next day. Which is really weird since all items appear propererly on the OMA website.

I solved the problem by contacting Microsoft Support. They helped me through this and found out that McAfee Groupshield was preventing the mobile devices to download new items since they were locked by the virus scanner.

I disabled "On-Access" scanning and enabled "Proactive scanning". This solved the problem sins proactive scanning doesn't scan the item immediately when it enters the Exchange database.

Microsoft told me that whatever virus scanner you're using on an Exchange server, you always need to disable its on-acces scan for this reason.
