Exchange 2010: Support for UPN credentials in OWA change password feature

Last year when we released Exchange 2010 SP1, we posted about the change expired password feature in Outlook Web App and how you can enable it by creating the ChangeExpiredPasswordEnabled registry entry. See So you want to change your expired passwords in OWA... for details.

Since then you've sent us many requests for supporting the use of User Principal Name (UPN) format in the same feature. Previously only domain\username format was supported when entering domain credentials.

We passed on that feedback to Exchange PMs and we're glad to let you know that the support for UPN credentials is now available in Exchange 2010 SP1 RU3-V3, which was released recently.

Note: At the time of this writing, Update Rollup 4 is the latest rollup available for Exchange 2010 SP1.

Exchange 2010 SP1: How to delete the First (or last) database and move the system mailboxes

When you try to delete the Default Mailbox Database (created with 1st installation of the Mailbox Role), you receive the error below

“This mailbox database contains one or more mailboxes or arbitration mailboxes. Before you can remove this mailbox database, you must disable, move or remove user mailboxes and move arbitration mailboxes.”


The First database contains the SystemMailboxes which are the Arbitration mailbox(es).

We have to move these system mailboxes to another database before of remove the Default Database.

1. Find the Arbitration Mailbox with EMS

Get-Mailbox -Arbitration |  Where {$_.Name -like "SystemMailbox*" } | ft –wrap

2. Now have to create a new move request

New-MoveRequest -Identity "SystemMailbox{1f05a927-32d1-4e19-8ea5-67eba859f541-yourGUID}" -TargetDatabase "dbxxxx"   

3. Verify if the move request was done


4. Remove the request

Remove-MoveRequest -Identity "the name of the request like Microsoft Exchange Approval Assistant"

FreeNAS 8.0 Simplifies Storage

The FreeNAS distribution is tailor-made for installation in a small office environment. It is an extremely low-resource network storage system that you can administer through a Web browser, but it supports high-end features like automatic backups, replication, LDAP or Active Directory authentication, and seamless file-sharing over NFS, CIFS, AFP, and even FTP and TFTP. The latest release — version 8.0 — is just a few weeks old, and it is the perfect time to take a look.

After Installing Exchange 2010 Service Pack 1, Searching via OWA or Outlook Online Mode Fails

With Exchange 2010 Service Pack 1, you may find that performing a search via Outlook Web App (OWA) results in an error message, “The action couldn’t be completed. Try again later.” Additionally, Outlook clients operating in Online Mode can no longer search for attachments or embedded emails.

What causes this issue?

This problem typically is a result of installing or upgrading a multi-role server (a server that has the Mailbox, Client Access, and Hub Transport roles installed) to SP1 and then removing the Hub Transport and Client Access roles, thereby leaving the server with only the Mailbox role installed.

There is a symbolic link for each language referenced in the registry, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex\Language. The symbolic links (ActiveX CLSID of the class used) allow for word breaking and stemming for the locale corresponding to the language.

During the Exchange 2010 Service Pack 1 uninstall process for the Hub Transport role, setup removes the symbolic links, regardless of the fact that the Mailbox role is still present. The removal of the symbolic links causes the generation of content indexing files to fail.
