Exchange throttling policy for Exchange Migration
What is Exchange throttling?
To maintain optimal performance and prevent a single user from using up all server resources, on-premise Exchange servers use throttling policies. While this ensures the server remains healthy and accessible to all users, it can pose problems during migrations if too many mailboxes are migrated at once, resulting in performance issues. Exchange throttling sets a limit on the number of concurrent call requests that can be executed at a time. To avoid migration errors and guarantee a seamless process, it is recommended to create a new throttling policy specifically for migrations. With this, you can ensure that the migration runs smoothly and without issue, while minimizing any potential performance hiccups that may arise.
How to avoid Exchange server throttling?
EdbMails application is designed to migrate the email and other items granularly to avoid throttling issues. In addition, you can create a custom throttling policy with limits higher than the default ones or even disable these limits and assign it to the user account used in the EdbMails application to perform the migration.
