The majority of Office 365 migrator and backup tools from Kernel Data Recovery utilize Exchange Web Services (EWS) for accessing Office 365. This encompasses the following tools:
- Kernel Office 365 Backup
- Kernel Import PST to Office 365
- Kernel Office 365 Backup & Restore
- Kernel Migrator for Exchange – Express Edition
- Kernel Office 365 Migration
- Kernel Office 365 Migrator for Lotus Notes
However, while using these tools, you may sometimes face the error:
"The server cannot service this request right now. Try again later"
This issue arises because EWS throttling has been enabled in Office 365. To address this problem, you will need to disable EWS throttling in your Office 365 settings.
How to Disable the EWS Throttling in Office 365?
Disabling EWS throttling can significantly enhance the speed of Office 365 data migration. Therefore, it is a viable option if you are encountering slow migration speeds.
- Log in to Office 365 using the Administrator credentials.
- Go to Support and click New Service Request.
- In the text box, write throttling, and it will show Increase EWS throttling Policy. Then click enter.
- Click Run Tests.
- A diagnosis will start for the throttling. Let it complete.
- After running the test, when the diagnostics show that Exchange web services are throttled, click on the Contact Support option.
- Please provide a title for your request, a description of the migration issues you're experiencing, a contact number, and an email address for authorized contacts. You will encounter a drop-down option that asks for your consent to record all calls required to resolve the service request. Select either 'Yes' or 'No' based on your preference. Finally, click the 'Contact Me' button to proceed.
- A service request has been initiated, and soon an agent will be assigned to investigate the request, and the issue will be resolved.
