Hi everyone, I have a very typical Exchange 2010 infrastructure (a LAB) with 2 CAS/HT load balanced, 2 MBX member of a DAG and an Exchange 2003 Server. when I use the enable-Mailbox cmdlet as follow it works as far as the Mailbox Name is unique: Enable-Mailbox -Database MBX02 -Identity UserDistinguishedName However, when I use MBX01 it fails stating that 2 mailboxes dtatabse have the name of MBX01 which is true : the Exchange 2003 has an MBX01 database. I tried : Enable-Mailbox -Database LABEX03\MBX02 -Identity UserDistinguishedName But it fails stating that it could not convert LABEX03\MBX01 to database name. How could the sample here work : http://technet.microsoft.com/fr-fr/library/aa998251.aspx Thanks

There are many things in an Exchange 2003 environment that cannot be managed using Exchange 2010 management tools. Check out this link.. http://msdn.microsoft.com/en-us/library/aa995972(EXCHG.140).aspx and this one http://technet.microsoft.com/en-us/library/aa995972(EXCHG.80).aspx Cheers

I know that Exchange 2003 cannot be fully managed by EMC. I just want to create a Mailbox in an Exchange 2010 DB that has the same name as another DB hosted on Exchange 2003. My question was : how to indicate the right DB to EnableMailbox cmdlet ? According to Technet Documentation it should be possible !

try with the DN of the databasename

How to get the DN ?

you can do something like $db=get-mailboxdatabase "server\database".distinguishedname Enable-Mailbox -Database $db -Identity UserDistinguishedName
