Preparing Public Folder Mailboxes for Public Folder Synchronization
Prepare public folder mailboxes for a successful public folder synchronization as follows:
- Ensure that the size of public folder data to be migrated does not exceed the size limit for the primary hierarchy mailbox. If public folder content in the source organization is larger than the limit in the target organization, to migrate it you will need to perform specific steps including creation of additional secondary hierarchy mailboxes in your target Exchange 2013 organization. For detailed instructions, see Appendix B. Migrating Large Public Folders to Exchange 2013 or Higher of Migration Manager for Exchange User Guide.
TIP: For general information on public folders in Exchange 2013, see http://technet.microsoft.com/en-us/library/jj150538(v=exchg.150).aspx.
- For each public folder mailbox consider adjusting the Recoverable Items quota according to the needs of your Exchange 2013 organization (by default, the limit is 30 GB per mailbox). If the quota limit is exceeded for a public folder mailbox, deletions of content in the source public folders will not be synced to that target public folder mailbox anymore.
To change the quota value for a public folder mailbox, invoke the following cmdlet:
Set-Mailbox -Identity PFMailbox -RecoverableItemsQuota 50GB
Creating Custom Throttling Policies
To prevent possible issues in an Exchange 2013 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 cmdlets in Exchange Management Shell for each Exchange Account:
New-ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name>
Set-ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name> -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited –PowerShellMaxConcurrency Unlimited
Set-ThrottlingPolicyAssociation -Identity <QMM_Exchange_Account_Name> -ThrottlingPolicy <QMM_Exchange_Account_Throttling_Policy_Name>
Restart-Service -Name MSExchangeThrottling
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.
For more details, see the related topics:
Setting up Target Exchange Organization for Internet Mail Flow between Target and Source Exchange Organizations
You need to establish Internet mail flow between the target and the source Exchange organizations. For that, you need to create an Internet Send connector and Receive connector on an Exchange 2013 Mailbox server that can be directly reached through the Internet.
To establish mail flow to and from the Internet through a Mailbox server, follow these steps:
- Create a Send connector (to send email from target Exchange 2013 organization to the Internet) on the Mailbox server.
- Modify the default Receive connector for the target domain to accept anonymous e-mail from the Internet
- Add the e-mail domain used for redirection to the list of accepted domains.
Each step is explained in further detail in the related subtopics.
