We have Exchange 2007 environment which contains 6 Failover Exchange clusters and each with 24 mailbox databases (total 144 mailbox databases). When there is a problem with replication of databases we needed to click every Failover cluster and check Copy Status of databases. To get rid of this hassle I wrote little script which lists all databases which Copy Status is not “Healthy”:

Get-MailboxServer | % { Get-StorageGroupCopyStatus -Server $_.Identity | ? {$_.SummaryCopyStatus -NotLike “Healthy” } }

For Exchange 2010 it would change little bit to:

Get-MailboxServer | % { Get-MailboxDatabaseCopyStatus -Server $_.Identity | ? {$_.Status -NotLike “Healthy” } }

Now I’m ready to check in couple of seconds the health of databases 🙂

I couldn’t connect via ActiveSync on my account. I’ve checked events on CAS server and I found:

Exchange ActiveSync doesn’t have sufficient permissions to create the “CN=Zilinec Ondrej – testovaci TS uzivatel,OU=TESTUSERS,OU=UZIVATELIA,OU=XXX,DC=XXX,DC=in,DC=XXX,DC=XX” container under Active Directory user “Active Directory operation failed on DCB1.XXX. This error is not retriable. Additional information: Access is denied.

Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

“.

Make sure the user has inherited permission granted to domain\Exchange Servers to allow List, Create child, Delete child of object type “msExchActiveSyncDevices” and doesn’t have any deny permissions that block such operations.
