Unable to change database path on Exchange 2010 in a DAG?

If you find yourself unable to change the database path of an Exchange 2010 database, check whether it is part of a DAG. See the screenshot for the missing option: If so, you cannot move it.

Issues with setting default language for Outlook Web App 2010

Now and then I get request to implement a default language for Outlook Web Access or App. This meant that users already had their language and regional settings set for OWA. Exchange only asks this the first time the user logs into OWA, this is because the language code is set to 0.

Recently a colleague of mine migrated the mailboxes from Exchange 2003 to Exchange 2010.

Fixing a broken OWA 2010 Virtual Directory

Several days ago a co-worker needed my assistance with a broken Outlook Web App 2010. A failed attempt to configure the root to redirect it to \owa unfortunately failed.

Trying to remove the OWA virtual directory with: Remove-OwaVirtualDirectory
