Exchange 2003 to 2010 migration Linked mailboxes and Disconnected mailboxes.

Hello,

I'm in the process of migrating from Exchange 2003 to 2010.  I have about half of the users moved over currently.  I have one new employee who started yesterday and she is only able to receive messages from certain internal users.  She was never on the Exchange 2003 server, only newly created on exchange 2010.  

When I look at her mailbox in EMS it appears to be fine and is linked to an AD account.  The strange thing is there is a Disconnected Mailbox with her name in EMC.  It is her full name. As in First name,  Middle Initial last name.  Let's call her Jane Q. Public  Her account in AD doesn't have this middle initial associated with it.  It's like she has two mailboxes.  One active and one disconnected.  The people who are unable to send her messages show her as Jane Q. Public in their address book while I (who can send e-mail to her) show her as just Jane public.  

On the disconnected mailbox in EMC if I click connect, select "user mailbox" there is no matching user and if I choose "Existing user" her name is not listed.  I assume this means her account in AD is already associated with a mailbox (Jane Public presumably).

So the question is how do I resolve this?  It seems like the OAB is out of sorts and I know this is the case because I am receiving OAB errors on all clients that have been moved to Exchange 2010 which may be a whole other issue.  The users who can't e-mail to this person see her as Jane Q public where as the ones who can see her as Jane Public in their OABs.  

I know this is confusing and I may not be explaining this very elegantly.  

Thanks.

Did the affected users send her some email when her mailbox was set as "Jane Q. Public" if so could be cache .... ask the same user to check with OWA ..... if on Users Outlook it shows as "Jane Q. Public" instead of "Jane Public" then try to download Full Address Book and check.

Are these users on a different Database or using Different version of Outlook ?
How many MBX and CAS servers do you have ?
Is the Exchange services running on all Exchange servers ?
What is the distribution set on OAB ?
How many OAB's do you have in the environment ?

I assume this means her account in AD is already associated with a mailbox (Jane Public presumably) - Yes

Rancy.  The user who is unable to send Jane Q. Public e-mails seems to have left for the day.  Radio silence, so I can't check via OWA because I don't have her password.

I deleted the entry for Jane Q. Public in her NK2 cache and tried again but it still tried to deliver to Jane Q. Public.  Our OAB is busted which I believe is the root of the issue.  Synch errors after the users are migrated.  I have moved the OAB to the Exchange 2010 server but the same issues persist.  

Same version of Outlook (2007)
one mailbox server one CAS server
Yes all exchange services are running
I don't know what the distribution set on OAB is.  How can I tell?  
One OAB

After talking to one of my guys who created the Jane Q. Public account yesterday, he was originally unable to get her to connect with Outlook at all to her mailbox so he deleted her AD account and mailbox altogether and created it on the Exchange 2003 server as Jane Public (this explains the disconnected Jane Q. Public mailbox), configured her Outlook, etc then later in the day moved the account to Exchange 2010.
Rancy.  The user who is unable to send Jane Q. Public e-mails seems to have left for the day.  Radio silence, so I can't check via OWA because I don't have her password - No worries can check that tomorrow :)

Our OAB is busted which I believe is the root of the issue - Why not try and play with a Brand new OAB ?

I don't know what the distribution set on OAB is.  How can I tell? -- Go to properties in EMC and check which server does it points to :)

Hello,   Why don’t you try renaming the user mailbox in EMC (which is showing disconnected) as the one in EMS (Jane public).  Here is the link for the same:

I believe the underlying issue is related to our address book issues.  I am going to start a new question related to just the address book problems.
