After adding additional mailboxes to Outlook (Tools > Email Account > Change > More Settings > Advanced > Add), when you retrace your steps you may find that you are unable to remove the additional mailbox(es) because it isn’t listed, even though the mailbox is still visible in the main Outlook pane. When right-clicking on the mailbox and selecting “Close Mailbox – Name” you may receive the following error:

Solution:

Navigate to the following in the registry:

HKCUSoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfilesDefault

Look through each of the folders, and delete the folder that correspond to the additional mailbox(es) causing an issue.

We had an issue recently when we migrated some exchange 2003 mailboxes onto an Exchange 2010 (Please note Exchange 2010 was SP1) Environment.

Basically after the migration all migrated users using Outlook in online mode could only see a blank Global Address List.

After looking into the issue we found that the resolution was to clear the value from the following attribute “msExchQueryBaseDN” via ADSIEDIT for the effected user.

After clearing the value the GAL suddenly appeared correctly

I believe Microsoft are looking into sorting this issue in Exchange 2010 SP2.

We have come across a problem with the new Service Pack 1 for Office and the CRM 2011 client for Outlook.

The symptoms are that calendar reminders do not pop up in Outlook which can cause some major problems for the end users.

We found that in our environment, if we removed the CRM 2011 client for Outlook the reminders would start working again. We then reinstalled the CRM client and found that the issue came back. Disabling the CRM add-ins in Outlook had no effect.

This issue has now been fixed which can be requested from the following URL:

UPDATE:

Microsoft have released a KB article detailing the error. They are currently working on a fix that should be released at the end of August or early September:
