MS Exchange ActiveSync Issue after mailbox moved

Faced an Exchange Active Sync issue after the mailbox migrate from Exchange 2003 to Exchange 2010, then the mobile device is unable to sync with Exchange 2010 with the following error found in the CAS server event log.

The event is 1053, source MSExchange ActiveSync and obviously the event stated is due to the permission issue because the Exchange server is unable to create the object under this user account.

Found a workaround from the Internet which posted by a blogger named Nick Mackechnie (http://blog.nick.mackechnie.co.nz). Hence, follow the same method as his.

Remove server information in email header for MS Exchange 2007/2010

An email message consists of three components, the message envelope, the message header, and the message body. The message header contains control information, including, minimally, an originator's email address and one or more recipient addresses. Usually descriptive information is also added, such as a subject header field and a message submission date/time stamp.


Above definition is from Wikipedia. 


When a user receive an email from another user B, basically from the email header, we are able to view the sender's (user B) email server name and ip address unless these information is purposely masked.   
In Exchange 2007/2010, these information (server name, IP) will be populated in the message header basically is to allow the ease troubleshooting on the mail flow.


However, if you like to protect these internal server information from showing to whole world, you may try this at your Exchange Server. It's pretty simple and straight forward. 

Basically you just need to create a new Hub Transport rule at your Exchange 2007/2010 Hub Transport Server.

Named the rule - i choose "Remove Header".

RPC encryption disabled by default in Exchange 2010 SP1

During one of my project on Exchange migration, i just realized that the default RPC encryption is disabled in Exchange 2010 SP1.

Below is the PowerShell command to retrieve the RPC encryption setting.

Get-RPCClientAccess | fl name, encryptionrequired (the results will list out the RPC encryption setting of all Exchange Servers)

Get-RPCClientAccess -Server ServerName | fl EncryptionRequired (the results will only list out the RPC encryption setting of specified server)

To enable/disable back the RPC encryption, just tweak the PowerShell command for "True" and "False"

Set-RpcClientAccess -Server ServerName -EncryptionRequired $True (enable encryption)

Set-RpcClientAccess -Server ServerName -EncryptionRequired $False (disable encryption)
