Hello,

While I migrating users I noticed that one don't have a database, and there is also an error in ecp :

The object domain.com/Users/SystemMailbox{0C5E1178-A163-4991-8A37-72184E7F53FB} has been corrupted, and it's in an inconsistent state. The following validation errors happened:

Database is mandatory on UserMailbox.

Also I have 5 System Mailbox??!! Do I need all of them? If not how and which to delete.

Thank you for help

Hi,

Thank you guys, that helped. Error is gone, and mailbox is in database :-)

In ADSI I noticed that home MDB field is empty, I copied from another. BUT there is home MTA field that have CN=Microsoft MTA\0ADEK:d8398166-61a0-43d3-8482-3e6fb49b0459,CN=Deleted Objects,CN=Configuration,DC=company,DC=com?? Other system mailbox don't have that ?! Is it OK? Should I live that or delete?

BTW. That system mailbox has Legacy mailbox type and I can see him in ECP on 2013 or EMC on 2010, is it OK? Other system mailboxes are not visible.

Hi,

Another strange detail about that system mailbox.

I run get-mailbox and now I see that this system mailbox is on server that not exist ?! Probably some old 2000 server. Because I run all 2003 and later server and don't know that name :-)

That is also vieable in ADSI: msExchHomeServer , same old organization name(pre ex 2007), and server name.

I think that I can also copy that field from another system mailbox ??

Yes I can, now it is on right server :-)

Now I have only one problem, other system mailboxes are listed in get-mailbox -arbitration, this is listed only in get-mailbox.

How to make him Arbitration ?? Or not ?
