Product

Device & OS
not provided
Scenario
Configuring email clients, third-party integrations, or custom applications that require a direct connection to Exchange services.
Observed behavior
The administrator requires the correct EWS URL, but needs to determine the exact address since endpoints can vary depending on the specific Microsoft 365 environment and service requirements.
Before you start

Ensure you have an active Microsoft 365 administrator account with the necessary permissions to access the Exchange Admin Center.

Solution 1Recommended

Locate the EWS URL via the Microsoft 365 Admin Portal

Access the Exchange Admin Center to verify your endpoints and differentiate between EWS, DNS, and Outlook on the web addresses.

The standard Exchange Web Services (EWS) URL is required when setting up certain email clients or applications to interact with Exchange servers. While the default endpoint is standardized for most commercial users, administrators should confirm their specific environment settings in the admin portal.

1
Sign in to Microsoft 365

Navigate to the Microsoft 365 admin portal and log in using your administrator credentials.

2
Open the Exchange Admin Center

From the main dashboard, open the Admin center menu and select 'Exchange'. Alternatively, you can bypass the main portal and go directly to https://outlook.office365.com/ecp/.

3
Identify the required service URL

Determine the exact type of address you need. Ensure you are looking for the EWS endpoint (typically https://outlook.office365.com/EWS/Exchange.asmx) rather than DNS records (such as MX or DKIM) or the standard Outlook on the web address.

Standard EWS Endpoint: For the vast majority of standard commercial Microsoft 365 tenants, the correct Exchange Web Services URL is https://outlook.office365.com/EWS/Exchange.asmx.

Frequently Asked Questions

What is the standard EWS URL for Microsoft 365?

For most commercial Microsoft 365 users, the standard Exchange Web Services (EWS) endpoint is https://outlook.office365.com/EWS/Exchange.asmx.

Is the Exchange Admin Center URL the same as the EWS URL?

No. The Exchange Admin Center is the web-based management portal for administrators (accessed at outlook.office365.com/ecp/), while the EWS URL is the API endpoint used by client applications to sync mail, calendar, and contacts.

Why do third-party applications ask for an EWS URL?

Third-party applications, email clients, and custom scripts use the EWS URL to connect directly to the Exchange server backend, allowing them to read and modify mailbox data securely.

Can I access the Exchange Admin Center without administrator credentials?

No, accessing the Exchange Admin Center (EAC) requires an account with administrative privileges assigned within your Microsoft 365 organization.
