Outlook 2003 or 2007 having issue updating meeting calendar.

Issue in Microsoft Outlook 2007 and 2004, in Windows Exchange Server 2003 environment.

We are currently having an issue affecting a number of our users where when a meeting is re-scheduled in the Outlook Calendar the old meeting entry isn't been removed from the calendar leaving a duplicate Calendar entry in both the old and new meeting times. We are using Exchange 2003 and a mixture of Outlook 2003 and 2007. Though only Outlook 2003 users have reported experiencing this issue up to yet.

Some user received undelivered messages, just like this example
Your message did not reach some or all of the intended recipients.
Subject: KING.NET Meeting - Delivery of Specifications (example subject)

The following recipient(s) cannot be reached: (example email address) on 1/6/2010 1:26 PM
Could not deliver the message in the time limit specified. Please retry or contact your administrator.

According to Microsoft technical website, this is due to corrupted mailbox.

HOWTO Fix Calendar Meeting updates?
The easiest approach is to move your Exchange user mailbox to another information store database. When you move a mailbox to another information store database, the Exchange system will auto-correct any issue found in the user mailbox. Then, move the user mailbox back to the original information store.

If you don't have the second Information Store database in your exchange environment, it's time for you to create one. Read other HOWTO articles.

You may also check the Exchange Server queues to see if any message is trying to go out. Here's a step by step procedure in Exchange Server 2003

  • Login to your Exchange System Manager
  • Click (+) in Administrative Groups
  • Click (+) first administrative group
  • Click (+) Server
  • Click (+) "your server"
  • Click Queues, and check the SMTP connector if you have any emails pending delivery.
The step-by-step procedure for Exchange Server 2007 is next.

Frequent Account Lockout in Active Directory

I have a user in Windows Pro 7, and Windows Server 2003 environment that is frequently account locked out. I tried many different scenarios to resolve this account lockout issue, from resetting his password, changing a new password, remove and re-join the domain, rebooting the workstation and active directory servers.

I tried to use the command prompt utility to run "rundll32.exe keymgrdll, KRShowKeyMgr" (case sensitive) to delete the account in Windows 7 password cache, and still no luck.

Still searching for answer ... Let me know if you encounter a similar issue in Windows Pro 7 and Windows Server 2003.
