Outlook and OWA show different Calendar Items

I have a weird situation where some, not all, Calendar items in an Exchange 2003 implementation do not behave/display consistently.  

Basically, the meeting organizer has the meeting on her Outlook Calendar, but it is totally absent from her OWA.  The meeting recipient has the meeting on his Outlook Calendar, *and* on his OWA, but the OWA item throws a 500 error if you try to open it.  The item is missing from his WM5/Activesync PDA.

Any idea how these are out of sync, and what can be done to troubleshoot?  I am flummoxed.

If your Exchange account is configured to store messages, calendar items, contacts, etc. in a Personal Folder (.pst file), then you will only be able to view your appointments when using the Outlook client, since Personal Folder data is stored on either your hard drive or on a network drive (H:\exchange). In order to view your calendar data from both Outlook and OWA, you need to store your data (calendar items, messages, etc.) on the Exchange server. To change your account configuration to the Exchange server, launch Outlook, select Tools/Email Accounts , click Next , in the "Deliver new email to the following location:" pull-down menu, select Mailbox - username (NID) and click Finish.

It's the Exchange mailbox items that are out of whack.  No PSTs are involved, and OWA never shows PST data anyway.

1) consider checking the AD permissions

2) Can you export the data using Exmerge and see if it shows up OK ?

3) It could be a corrupted mail DB that  needs repairing.


I hope this helps !

you can try Exit Outlook, click Start, point to Run, type outlook /cleanreminders, and then click OK. This will fix if there are any contains corrupt reminder items. and then try to view in owa.

Thanks,

Hi SysExpert:

I think perms are fine as some items work as expected and some do not.

I will try Exmerge this evening and let you know

It likely is a corrupted mail DB.  Do you recommend a eseutil /p hard repair in this case?

If you are backed up, it certainly should not hurt.

We decided that the corruption was very small and limited and handled it a different way.  Your advice was spot on though, SysExpert.  Thanks.
