Hello, @Allen, Jim

Welcome to the Microsoft Q&A platform!

To see which accounts are actively using Exchange Web Services (EWS) in Exchange Online (EXO), you can use the Exchange Online PowerShell.

Here are the commands and test results:


Connect-ExchangeOnline


Get-CASMailbox | Select-Object DisplayName, EwsEnabled

User's image

For more detailed usage information, you might need to check the Azure AD sign-in logs to see which applications are using EWS.

thanks, i understand how to see if it is enabled. I want to know what accounts are actively using EWS? I'd like to see sign-in logs or user activity that shows when EWS is used exclusively, so we know what will occur when EWS is disabled.

To determine which accounts are actively using Exchange Web Services (EWS), you can indeed check the sign-in logs and user activity to see EWS usage.

You can utilize the Unified Audit Log in the Microsoft 365 Compliance Center. Navigate to "Audit" and search with the activity "EwsAccess" within your desired date range. This will show logs specifying which accounts have been accessing EWS. You can automate this with PowerShell using the Search-UnifiedAuditLog cmdlet to export relevant data into a CSV file for further analysis.

Azure Active Directory (Azure AD) sign-in logs also provide insights into EWS activity. In the Azure portal, go to "Azure Active Directory" > "Sign-ins" and apply filters for "Client App," selecting "Exchange Web Services." Review these logs to identify which users have been logging in via EWS and gather detailed sign-in information.

After gathering data from the Unified Audit Log and Azure AD sign-in logs, you'll be able to pinpoint which users are actively using EWS. With this information, you can communicate with those users and plan for alternative solutions if you decide to disable EWS, ensuring minimal disruption to their workflow.
