Understanding Exchange 2019 server throttling
- Aug 12, 2019
You get the "micro delay applied" message and then you might get blocked. See for example https://www.quadrotech-it.com/blog/office-365-exchange-online-powershell-throttling/
You can try to disable all throttling parameters for an admin account called "MigrationWiz":
- Open the Exchange Management Shell.
- Type the following command and press Enter:
New-ThrottlingPolicy MigrationWizPolicy
- Type the following command and press Enter:
Set-ThrottlingPolicy MigrationWizPolicy -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited
- Type the following command and press Enter:
Set-Mailbox "MigrationWiz" -ThrottlingPolicy MigrationWizPolicy
Option 2: Disable throttling against all user accounts (if migrating using an admin account and using impersonation). This way the admin account can migrate at a faster rate because it impersonates user accounts, which are not subjected to throttling.
