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.
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:
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:
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.
