How to Find Microsoft Outlook Connection Type and Authentication Method
Question details
The user needs to locate and understand the specific connection type and authentication method used by their Microsoft Outlook and Exchange primary mailbox after it has been configured via Autodiscover.
- Product
- Microsoft Outlook / Exchange
- Device & OS
- not provided
- Scenario
- Checking email account settings to verify connection protocols (like MAPI, IMAP) and security configurations (like Basic or Modern Authentication).
- Observed behavior
- Autodiscover configures the mailbox automatically based on organizational settings, leaving the user unsure of which specific protocols and authentication types are actively being applied to the connection.
Ensure you have access to your Microsoft Outlook desktop client. To check specific organization-wide authentication logs, you will need administrative privileges for the Microsoft 365 admin center.
Check Connection Type within Microsoft Outlook Account Settings
You can view the primary connection protocol currently applied to your mailbox directly through the Outlook client settings menu.
Common connection types include MAPI, Exchange ActiveSync, IMAP, and POP. The Account Settings menu will display the overarching protocol established by Autodiscover.
Launch Microsoft Outlook, click on the 'File' tab in the top left corner, select 'Info', and then click the 'Account Settings' button.
From the drop-down menu that appears, click on 'Account Settings...' to open the detailed email accounts window.
Under the 'Email' tab, locate your primary mailbox in the list. Check the 'Type' column next to your email address to see your connection type (e.g., Microsoft Exchange, IMAP/SMTP).
Use the Outlook Connection Status Tool
The built-in Connection Status dialog provides real-time, detailed information on the network protocols Outlook is currently using to communicate with the Exchange server.
Verify Authentication Method via Microsoft Entra Admin Center
Since authentication methods depend heavily on organizational configurations, administrators can definitively check the sign-in logs to see what method a specific client used.

Frequently Asked Questions
What is the difference between Basic and Modern Authentication in Microsoft Exchange?
Basic Authentication passes simple username and password combinations to the server, which can be vulnerable to interception. Modern Authentication relies on token-based authorization (OAuth) and actively supports advanced security measures like Multi-Factor Authentication (MFA), smart cards, and third-party SAML identity providers.
Why does Autodiscover choose a specific connection type for my mailbox automatically?
Autodiscover analyzes your organization's Exchange server configurations alongside the capabilities of your specific email client. It will automatically default to the most secure, stable, and feature-rich protocol available, typically selecting MAPI over HTTP or Exchange Web Services (EWS) for modern Outlook clients.
Can I manually change my Outlook connection type from Exchange to IMAP?
You cannot directly convert an existing Exchange account profile to IMAP within Outlook. To use IMAP, you must add the mailbox as a brand new account, choose the manual setup option, and specifically input the IMAP incoming and SMTP outgoing server settings provided by your administrator.
Where can I find out if MFA is enabled for my Exchange account?
As an end-user, you will know MFA is active if you are prompted to verify your identity using a mobile app, text message, or call during login. To see exact security policy configurations, you must contact your Microsoft 365 administrator, as they control authentication methods at the organizational level.
