Today I spent half a day of debugging one weird problem. One of my customer just upgraded to Exchange 2010. They wanted to use ouf of office assistant. When they clicked in outlook clients on OOOA they’ve got error:
Out of office assistant error
One of our customer migrated his whole IT infrastructure into another datacenter. We powered off virtual machines at production site and powered on cloned versions of virtual machines. Domain Controllers were up all the time. Only member servers’ clones moved into another datacenter. They’ve ran for three days in another datacenter. Active Directory domain was up all the time. After tests we deleted clones in another datacenter and powered on virtual server in primary datacenter – their friday’s copies. And now we had problems on couple of servers.
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.

This weekend was again migrating for Exchange 2010 🙂 And right now other problems and solutions 🙂
On one CAS server I logged in via OWA and I’ve got internall error 500 from IIS 7.0.
This days I was installing one Exchange 2007 server into existing Exchange organization (two other Exchange 2007 servers). I enabled one new server all features which Exchange 2007 brings to clients: Outlook Anywhere, Autodiscover, ActiveSync. After couple days we discovered that by this setting not only local users were affected, but all clients connecting into Exchange Organization (also those connecting to two old servers).
Here is a short script to find out the size of mailboxes in your Exchange 2010 infrastructure. This information is not visible in EMC.
Get-MailboxStatistics -Server 'mailserver' | select DisplayName, TotalItemSize | sort TotalItemSize
Microsoft people should leave good things in GUI consoles and not force admins into powershell.
When I migrate mailboxes between Exchange servers I increase numbers of move requests because two is really limiting in nowadays network and servers speeds.
Today I was migrating mailboxes from Exchange 2003 to new server Exchange 2010. Almost all accounts were working fine except couple. I receive following error:
Today I spend about one hour debugging weird problem. When I migrated physical machine into VMWare I couldn’t connect via RDP into it.
It’s getting on my nerves to enable telnet client everytime I need to debug something on Windows 2008 or Windows 7.
