Description
This document contains instructions on how to temporarily increase the EWS (Exchange Web Services) throttling policy limits in Exchange Online / Outlook mailboxes (Office 365).
This article only applies where backup jobs are encountering throttling on Exchange Online / Outlook mailboxes. It is not supported on OneDrive, Personal Site or SharePoint Site collections. For example, when throttled the following messages are logged the backup log or report "Will retry in 57 second(s). Reason=Request is being throttled".
The option to change EWS throttling settings through the automated help pages has been introduced by Microsoft as a response to the COVID-19 crisis. It is possible that this option may become unavailable over time.
Steps
-
Sign in to your
Microsoft 365 admin center.
-
Click the ? (Help) icon in the upper-right corner of the page. If the switch at the upper part of the Help pane is pointing to Support Assistant, change it to Search.
Enter ews and then select Increase EWS Throttling Policy from the suggestion list.
-
Click the Run Tests button.
-
If the Exchange Web Service on the Office 365 organization is throttled, you will have the option to ease the throttling policy settings for 30, 60 or 90 days.
Select your required duration (Days) from the drop-down menu.
However, if the Exchange Web Service on the Office 365 organization is not currently throttled, then no further options are provided.
- Click Update Settings to confirm. The changes should take effect within 30 minutes.
