Exchange 2010 Attendant homeMDB Attribute Mailbox Database 0365048811

Hi,
we migrated from Exchnage 2007 to 2010 and the system Attendant homeDB Attribut points to the autocreated DB named "Mailbox database 0365048811.

When I want to use EXFolders from the exchange-server in the newest version with right credentials it says:
Error: the mailbox /o=.../ou=.../ou=Exchange Administrative Group [FYDIBOHF23SPDLT]/cn=Configuration/cn=Servers/cn=Exchangename/cn=Microsoft System Attendant cannot be opened.

We deleted an empty public folder database after migrating to 2010 without errors.
Now we have no public folders anymore.

Schould I change the homeDB attribute to an "normal" Database?
Will I get more errors when I change it?
Please help

Does that database exist?

The system mailboxes can be moved to another database and often moving the mailbox will resolve issues with accessing them.

I wouldn't manually change the HomeDB value though.

Thanks for Your answer, I was on holydays.

Yes the database exists.

Moving the mailbox is to be done by changing the Attribute:

Hi

Go through the following link which explains more about the System Attendant mailbox

http://blogs.technet.com/b/evand/archive/2004/12/21/329172.aspx

If you want to move the System Attendant mailbox to another database, you can do it from ADSIEDIT. Follow the below steps

1) open ADSIEDIT.msc

2) connect to the configuration container

3) Expand CN=Configuration,CN=Services,CN=Microsoft Exchange, CN= "OU Name", CN=Administrative Groups,CN= Exchange Administrative Group, CN=Servers, CN="Server name", CN=Microsoft System Attendant.

4) Right click CN=Microsoft System Attendant and select properties

5) select the attribute "Home MDB". you will find the DN of the database which is currently holding the System Attendant mailbox. you can change this to the DN of the database to which you need to move the System Attendant mailbox.

Let me know if this helps

Thanks

The guide to follow is this one:

While it is designed for missing attributes, it should work in this scenario as well.
