Upgrading Microsoft Exchange 2003 to Microsoft Echange 2007

Asked By 50 points N/A Posted on -

Hi experts,

These past few days, I am trying to upgrade my MS Exchange 2003 to MS Exchange 2007.

I have tried it for several times. However, an error message pop-up when I view the properties of a recipient with spaces in its alias or when viewing the properties of the offline address book.

I don't understand what's happening. Can someone help me how to respond to these error? Thanks!


The properties on 'Schedule+ Free Busy Information – First Administrative Group' have invalid data.If you click OK, default values will be used instead and will be saved if you do not change them before hitting Apply or OK on the property page. If you click cancel, the object will be displayed read-only and corrupted values will be retained. The following values have invalid data: Alias.

Hello Lee,

It happened because Exchange 2007 does not accept Spaces (leading/trailing or in between) on Aliases.

In case such an object was created on Exchange 2003 (which allowed spaces in Alias) then while accessing properties (from Exchange 2007 server) of such an object you will get error.

You may correct this error by opening object from an Exchange 2003 server and remove spaces in alias.


You can use below command in Exchange 2007 Shell. This command will search for all mailboxes with spaces in Alias and fix the error.

Note: You will need "Exchange Recipient Administrator" rights to run below command.

Get-Mailbox | Where {$_.Alias -like "* *"} | ForEach-Object {Set-Mailbox $_.Name -Alias:($_.Alias -Replace " ","")}
