Installing new Exchange 2010 on Server 2008r2 in Server 2003 domain with an existing Exchange 2003 Server.
Getting this error (see attached screen shot).
I ran this command:
adfind -default -f "&(objectcategory=person)(
s=user)" samaccountname displayname homemdb -nodn -csv > c:\users.csv
And didn't find any users whose homemdb is NOT in the existing mail server.
I did have one aborted install of Exchange2010 on this domain and did create one test mailbox and then ended up deleting everything... I thought. But I think that test mailbox might be my problem.
But it's not in Active Directory Users and Computers and it's not in the above users.csv generated by the adfind statement.
Thanks for any ideas on how to find my bad object.
