(Exchange 2007) I have a number of mail enabled users with the ExchangeVersion attribute set with this value: 0.0 (6.5.6500.0) Can I update this via powershell? Will it be problem moving to Exchange 2010? Thanks!

I wouldn't tinker with it the objects probably didn't get "upgraded" sometimes they don't get upgraded unless they are "touched" again. In either case I doubt it will cause any issue for you. Try doing set-mailbox user -applymandatoryproperties and see if it updates the object.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I did not test it, But I belive you can change it thru ADSI Edit. But if you are going to move it to 2010 server then what is need to do it. It should get change once it will migrate to exchange 2010.Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

Hi, Creating an Exchange 2007 mailbox through the Exchange 2003 extensions to the Active Directory Users and Computers console is not supported. If an Exchange 2007 mailbox is created with this tool, it will be identified as a legacy mailbox, even though it resides on an Exchange 2007 server. Use the ApplyMandatoryProperties parameter to modify the mandatory properties of a mailbox in this state to correct the problem and remove the legacyMailbox tag from the mailbox.

Thanks for the advice. These are mail enabled, not mailbox enabled and the -applymandatoryproperties is not an option for this type of mail user.

Which type of the mail enabled object? Is it a mail enabled public folder?Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.

These are mail enabled users

Mail enabled user? This type of object should be able to apply this command. set-Mailbox User_Name –ApplyMandatoryProperties As my test, mail enable public folder can’t apply the command. Did you read the link I post above?

Thanks for the links. This Exchange object type does not accept the set-mailbox cmdlet. These are not public folders.

Could you please post a screen shoot? I think there must be some misunderstanding between you and me. As my test, Exchange 2007 supports the above command.

Hi AD EX, Do you have any update?

here is a copy of the powershell output. I've replaced my test user with "<user>". Note the recipienttype and the error. We are dealing with a MailUser object not a UserMailbox. [PS] C:>get-mailuser <user> | select name,recipienttype,exchangeversion | ft -autosize Name RecipientType ExchangeVersion ---- ------------- --------------- <user> MailUser 0.0 (6.5.6500.0) [PS] C:>set-mailbox <user> -ApplyMandatoryProperties Set-Mailbox : <user> is not a mailbox user. At line:1 char:12 + set-mailbox <<<< <user> -ApplyMandatoryProperties + CategoryInfo : NotSpecified: (0:Int32) [Set-Mailbox], ManagementObjectNotFoundException + FullyQualifiedErrorId : 8B3E6183,Microsoft.Exchange.Management.RecipientTasks.SetMailbox

Can you try with this once Get-User -Filter "ExchangeVersion -Eq "6.5.6500.0" Check whether all the users are pulled out, if yes run Get-User -Filter "ExchangeVersion -Eq "6.5.6500.0" -ApplyMandatoryProperties Else Get-User "Name of the user" -ApplyMandatoryPropertie

Similar problem with this approach. The -ApplyMandatoryProperties does not work with the set-user cmdlet.

Ok, I reproduce a similar issue. I created a use via ADUC, but I didn’t mail enable the use. I run this command: Get-user test |select name, recipienttype, exchangeversion Result: Name RecipientType ExchangeVersion Test User 0.0 (6.5.6500.0) Get-user administrator |select name, recipienttype, exchangeversion Result: Name RecipientType ExchangeVersion Test UserMailbox 0.1 (8.0.535.0) Set-Mailbox test –applyMandatoryProperties Result: Set-Mailbox: test is not a mailbox user. After I mail enabled test, the Exchange version update to 0.1 (8.0.535.0) It seems you didn’t mail enable the user. As KB 931747 said, This issue may occur if the following conditions are true: 1. The mailbox was created in the Active Directory Users and Computers snap-in on a server that was running Microsoft Exchange Server 2003. 2. The mailbox was moved to an Exchange Server 2007 server or an Exchange Server 2010 server . Could you please try to create a new mailbox via EMC, and check the Exchange version of the user? For the users in question, could you please try to remove mailbox and enable a new mailbox via EMC. Before you do that, remember backing up their files.

Thanks for doing those tests. You are confusing the the terminology between mail enabled and mailbox enable. These are mail enabled users that have external addresses. At this point I think the only thing I can do is to remove the exchange attributes and then mail enable them (not mailbox enable) to correct the attribute. I was hoping that I could do this on a mail enabled user the same way it can be done on a mailbox enabled user.
