Email missing from Outlook, but fine in OWA


Using SBS2008 (Exchange 2007). We have a user who is missing all sent email more than a few days old, when using Outlook 2010. I've tried logging onto another PC, and without offline mode, but the same issue.

When using cached mode, "Sync Issues" shows a lot errors. These are a few of them:

21:07:04         "EC0300000918401006FCFFFFDA750010"
21:07:04         "0F0104801A5E401006FCFFFF01494010"
21:07:04         "06FCFFFF"
21:07:04 Error synchronizing folder
21:07:04              [80070057-501-80070057-560]
21:07:04              The client operation failed.
21:07:04              Microsoft Exchange Information Store

When not using cached mode, then there are no sent emails at all. The Sent folder remains empty.

However, when using OWA, the email is present.

Also, there are Calendar sync failures, so when dismissing an event, the event is never dismissed, and returns a few moments later.

Any ideas?
Thank you!

The error message indicates that you are connecting to an Exchange Server?    What version of Outlook are you using, and what version of Exchange are you connecting to?  What is the operating system of the desktop/laptop you're having issues with.

Has this always been a problem or only just start happening?

Hi Cris.

Outlook 2010
Exchange 2007 (as indicated above)
Win 7 Pro.
Just started happening.

Have you tried to create a new Outlook profile for this user? Also how big is the mailbox for this user? Creating a new Outlook profile will determine if this is something with the Outlook client itself, which it probably is.

if the Outlook profile does not work, when try creating a new Windows Profile and see if that corrects the issue.

You could also run Outlook in safe mode to see if there are any issues with 3rd party add-ons
outlook.exe /safe

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

And how big is the .OST file on the computer...I'd probably just blow away the Profile and recreate it.
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
If you experienced the same problem on another system with cached mode turned off, then the problem is not related to the profile. However, I would delete and recreate the email profile, just to be sure I'm not misreading what you said.

Just to clarify what is going on, the user's sent mail is missing from the sent folder in Outlook, but is okay on OWA? If they send a new message from Outlook, is it still the same problem? Do sent messages continue to disappear?

By chance, are they using another device to access their mail, like an iPhone or BlackBerry?

It seems that the Exchange database is corrupt.

Thanks anyway.

I've requested that this question be deleted for the following reason:

Question not answered. I found that the issue was due to Exchange database being corrupted.
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
That is good information to know. From my perspective it would be better if you accepted your post about the EDB file being corrupted as the solution. Then others can benefit from your experience.
Cris HannaSr IT Support EngineerCommented:
I understand that by deleting you get credit back.  And congrats for finding the solution to your problem.  But as Brian suggests, the reason that EE works so well is because people share knowledge.  if the question is deleted, no one will ever benefit from your experience.

I can agree with that. I'll leave this here.

It was an odd issue though. OWA has no problem reading the mail store, but Outlook was completely confused.
