Creating Administrator Mailboxes for Public Folder Synchronization

Administrator mailboxes should be created on all Exchange servers involved in public folder synchronization. These mailboxes will be used to access the public folder tree folder when creating public folder synchronization jobs.

The administrative mailbox selected for public folder synchronization should reside in a private mailbox database located on the same server as the public folder database. The mailbox database should be also associated with that public folder database. To set this association, in Exchange Management Console open properties of the mailbox database and specify the public database as Default public folder database on the Client Settings tab.

Caution:

  • The administrator mailbox specified for the synchronization job should not be changed during the synchronization process.
  • The administrator mailboxes should not be included in mailbox or calendar synchronization jobs.

Creating Custom Throttling Policies

To prevent possible issues in an Exchange 2010 Service Pack 1 or later organization, you should create custom throttling policies, apply them to the Exchange Accounts and then restart the Microsoft Exchange Throttling Service.

To do this, run the following PowerShell commands for each Exchange Account:

New-ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name>

Set-ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name> -PowerShellMaxConcurrency <MaxConcurrency>

Set-ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name> –EWSMaxConcurrency $null –EWSPercentTimeInAD $null –EWSPercentTimeinCAS $null –EWSPercentTimeInMailboxRPC $null –EWSMaxSubscriptions $null –EWSFastSearchTimeoutInSeconds $null –EWSFindCountLimit $null

Set-ThrottlingPolicyAssociation -Identity <QMM_Exchange_Account_Name> -ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name>

Restart-Service -Name MSExchangeThrottling

where MaxConcurrency is the number of Migration Agent for Exchange (MAgE) instances simultaneously working with Exchange 2010 server, multiplied by the value of 5.

NOTE: To ensure stable operation of MAgE agents when working with Microsoft Exchange 2010, you should increase the number of permitted user connections. For that, change the value for the MaxSessionsPerUser parameter using the client throttling policies, as follows:

  1. On the computer that hosts the Microsoft Exchange CAS server, in %Program Files%\Microsoft\Exchange Server\V14\Bin, open the microsoft.exchange.addressbook.service.exe.config file in a text editor.
  2. Change the value of the MaxSessionsPerUser parameter to 100000.
  3. Save and close the file.
  4. Restart the Address Book service.

 

Setting Up Connection with the Source Exchange Organization Using SMTP Connectors

This section describes how to set up a connection with the source Exchange organization using SMTP connectors. On this step you may need to coordinate with the administrator of the source Exchange organization to set up the connection properly.
