Understanding the Exchange Server name associated with your Outlook profile can be crucial for troubleshooting, configuration, or administrative tasks. Microsoft Outlook connects to an Exchange Server to provide mailbox access, calendar, contacts, and other collaboration features in an enterprise environment.
This comprehensive guide explains multiple methods to identify the Exchange Server name directly from Microsoft Outlook, covering various Outlook versions and approaches. Whether you’re a user, IT administrator, or technician, you will find step-by-step instructions to retrieve this information effectively.
Why Knowing the Exchange Server Name Matters
The Exchange Server name is the address or hostname of your organization’s mail server that Outlook connects to. You may need this information to:
- Configure Outlook on a new device manually
- Set up mobile devices or third-party clients
- Troubleshoot connection or synchronization issues
- Check server details for security audits
- Communicate with your IT support team effectively
Note: In many modern environments, especially with Exchange Online (Office 365), the server name may be a generic address or may not be directly visible. However, the following methods will help uncover the Exchange Server information for most on-premises or hybrid deployments.
Method 1: Using Outlook Account Settings
The simplest way to find the Exchange Server name is through the Outlook application’s account settings. This method works well for Outlook 2016, 2019, and Microsoft 365 versions.
Step-by-Step Instructions
- Open Microsoft Outlook.
- Click on the File tab located in the top-left corner.
- Select Account Settings, then click on Account Settings… again from the dropdown.
- In the Email tab, select your Exchange account from the list.
- Click on Change… to open account configuration information.
- Look for the field labeled Server or Microsoft Exchange Server. This is the Exchange Server name.
Example: The server name might appear as exchange.company.com or an IP address.
Tip: In Outlook versions that use Auto Account Setup, the server field may be greyed out or hidden. In such cases, use other methods described in this guide.
Method 2: Using Outlook Connection Status Window
Outlook provides a detailed connection status window that reveals the server to which it is connected. This method gives real-time connection details and is useful for all Outlook versions.
How to Open Connection Status
- Hold down the Ctrl key and right-click the Outlook icon in the system tray (near the clock).
- Select Connection Status… from the context menu.
A window will open showing active connections. The Server Name column displays the Exchange Server name or IP address.
| Column | Description |
|---|---|
| Server Name | The Exchange Server or Client Access Server (CAS) hosting your mailbox |
| Port | The network port used for the connection |
| Encryption | Shows whether the connection is encrypted (SSL/TLS) |
| Status | Current connection status (e.g., Connected, Disconnected) |
Note: If multiple servers appear, look for the one with the highest connection time or the one marked active.
Method 3: Checking Outlook Profile XML Files (Advanced)
For more technical users or administrators, Outlook stores profile configuration data in XML files that contain server names and connection details. This method requires locating specific files on the computer.
Locate the Outlook Profile XML File
The path to the XML file depends on your Windows version and Outlook profile name, but generally, it can be found here:
- Windows 10/11:
C:\Users\[YourUsername]\AppData\Local\Microsoft\Outlook\Profiles\[ProfileName]\
Look for files such as Outlook.xml or profile*.xml. Opening these files in a text editor (e.g., Notepad) may reveal entries containing ServerName or similar attributes.
Example XML Snippet
<AccountSettings>
<Account>
<ServerName>exchange.company.com</ServerName>
<Mailbox>[email protected]</Mailbox>
</Account>
</AccountSettings>
Warning: Modifying these files directly can corrupt your Outlook profile. Only use this method for reading purposes.
Method 4: Using the Windows Registry (For Experienced Users)
Outlook stores profile and server information in the Windows Registry. This method is intended for experienced users and administrators who understand registry editing.
Steps to Find Exchange Server Name via Registry
- Press Win + R, type
regedit, and press Enter to open the Registry Editor. - Navigate to the following key:
HKEY_CURRENT_USER\Software\Microsoft\Office\[version]\Outlook\Profiles\[profile name] - Within your profile, look for subkeys related to 9375CFF0413111d3B88A00104B2A6676. This GUID contains account information.
- Search the values for strings containing your Exchange server name or mailbox information.
The exact location and structure may vary depending on Outlook and Office versions.
Important: Back up the registry before making any changes. Editing the registry incorrectly can cause system instability.
Method 5: Using Outlook Web Access (OWA) Settings
If you have access to Outlook Web Access (the web-based version of Exchange), you can sometimes deduce the Exchange server name from the URL or settings.
- Log in to your Outlook Web Access portal (usually something like
https://mail.company.com/owa). - Check the URL for the domain name, which often corresponds to the Exchange server or Client Access Server.
- In some OWA versions, clicking on the settings gear icon and selecting About or Options reveals server info.
Note: In Office 365 environments, the server is usually cloud-hosted, and the server name may be a Microsoft-managed domain.
Method 6: Using Command Prompt and Network Tools
Network utilities can help identify the Exchange server your Outlook client connects to by monitoring network connections.
Using Netstat Command
- Close Outlook.
- Open Command Prompt (press Win + R, type
cmd, and press Enter). - Type the following command and press Enter:
netstat -n | findstr 443 - Open Outlook again and monitor new established connections on port 443 (HTTPS).
- Look for IP addresses connected on port 443 related to Exchange.
Once you have IP addresses, use the nslookup command to resolve the server name:
nslookup [IP address]
This will provide the hostname, which often corresponds to the Exchange Server.

Additional Tips and Considerations
- Autodiscover Service: Modern Outlook clients use Autodiscover to automatically configure server settings. Sometimes the server name will be internal and may not be accessible externally.
- Cached Mode: If Outlook is in cached mode, some server information might be delayed or hidden. Try disabling cached mode temporarily to get real-time server info.
- Exchange Online (Office 365): Server names may not be traditional hostnames but URLs like
outlook.office365.com. This is standard for cloud mailboxes. - Permissions: Some of these methods require appropriate permissions on the client machine or network. If you lack access, contact your IT department.
- Third-Party Tools: There are specialized diagnostic tools like Microsoft Remote Connectivity Analyzer or MFCMAPI that provide deeper mailbox and server insights.
Remember: Always ensure you follow your organization’s policies when accessing or modifying Outlook and Exchange settings.
Frequently Asked Questions (FAQs)
