Your Outlook 365 client stores server connection details in a location you might not expect. If you are wondering how to find exchange server name in outlook 365, the answer is simpler than most people think. Many users assume they need to contact IT support, but the information is actually hidden right inside your email settings.
Knowing your Exchange server name is essential for configuring mobile devices, troubleshooting connection issues, or setting up advanced email clients. This guide walks you through every method step by step, so you can locate it in under two minutes.
Why You Need Your Exchange Server Name
Your Exchange server name acts like a digital address for your mailbox. Without it, your email client cannot connect to the server to send or recieve messages. You might need this name when:
- Setting up Outlook on a new computer or phone
- Configuring a third-party email app like Apple Mail or Thunderbird
- Diagnosing sync errors or slow performance
- Connecting to a public folder or shared mailbox
Microsoft 365 users often have a server name that looks like “outlook.office365.com” or something similar. But the exact value depends on your organization’s setup.
How To Find Exchange Server Name In Outlook 365
This is the most reliable method for any Outlook 365 desktop client. Follow these steps exactly as written.
Step 1: Open Outlook And Go To File
Launch Outlook 365 on your Windows or Mac computer. Click the File tab in the top-left corner of the ribbon menu. This opens the backstage view where account settings are stored.
Step 2: Access Account Settings
In the File menu, look for the Account Settings button. It is usually located near the bottom of the left-hand column. Click it, then select Account Settings again from the dropdown menu.
Step 3: Double-Click Your Email Account
A window titled “Account Settings” will appear. You will see a list of your email accounts. Find the one you want to check, then double-click it. Do not click the “Change” button yet—just double-click the account name.
Step 4: Locate The Server Name Field
After double-clicking, a new window opens called “Change Account.” Look for the field labeled Server or Exchange Server. This is your Exchange server name. It might say something like “outlook.office365.com” or “mail.contoso.com.”
Write this down exactly as it appears. Even a small typo can cause connection failures.
Step 5: Check The Offline Settings (If Needed)
If the Server field is blank or grayed out, click the More Settings button. Then go to the Connection tab. Under “Exchange Proxy Settings,” you might see a different server address used for external connections. This is also valid.
Alternative Method Using Outlook On The Web
If you cannot access the desktop app, you can find the server name through Outlook on the web (formerly known as Outlook Web App). This method works on any browser.
Step 1: Log Into Outlook On The Web
Go to outlook.office.com or your organization’s specific webmail URL. Sign in with your work or school credentials.
Step 2: Open Settings
Click the gear icon in the top-right corner. A settings pane slides out from the right. Scroll down and click View all Outlook settings at the bottom.
Step 3: Go To Mail > Sync Email
In the settings window, navigate to Mail in the left menu. Then click Sync email. Under “POP and IMAP,” you will see server names for incoming and outgoing mail. However, the Exchange server name is usually listed under “Exchange ActiveSync” or “Exchange account settings.”
Step 4: Look For The Server Address
In the Sync email section, find the line that says “Exchange server” or “Server address.” It is often a subdomain like “outlook.office365.com” or “pod51000.outlook.com.” Copy it exactly.
Using Command Prompt Or PowerShell (Advanced Users)
For IT professionals or advanced users, you can retrieve the server name using a command-line tool. This method is faster if you manage multiple accounts.
Method A: Using Outlook’s Test Email AutoConfiguration
Hold the Ctrl key and right-click the Outlook icon in your system tray. Select Test Email AutoConfiguration. Enter your email address and password, then click Test. The results will show your Exchange server name under “Server Settings.”
Method B: Using PowerShell With Exchange Online
If you have admin access, open PowerShell as administrator. Run the following command:
Get-Mailbox -Identity "your.email@domain.com" | fl ExchangeGuid, ServerLegacyDNThis returns the server distinguished name, which includes the server name. Not for casual users, but very accurate.
What If The Server Name Is Not Displayed?
Sometimes Outlook hides the server name for security reasons. This happens especially with Microsoft 365 Business accounts. If you see a blank field or a generic name like “Outlook,” try these fixes:
- Update Outlook to the latest version
- Check if you are using a cached Exchange mode profile
- Ask your IT admin for the correct server address
- Use the Outlook on the web method instead
In rare cases, your organization might use a custom server name that is not publicly visible. Contact your help desk if all else fails.
Common Server Name Formats For Outlook 365
Knowing the typical format helps you verify if the name you found is correct. Here are the most common patterns:
- outlook.office365.com – Standard for Microsoft 365
- podXXXXX.outlook.com – Legacy or multi-tenant servers
- mail.yourcompany.com – Custom domain setups
- smtp.office365.com – Outgoing mail server (SMTP)
- imap.office365.com – For IMAP connections (not Exchange)
Your server name should not contain spaces or special characters. If it does, double-check the spelling.
How To Verify The Server Name Works
Once you have the server name, test it before using it in another app. Here is a quick way to confirm it is correct:
Step 1: Open Outlook And Go To Account Settings
Follow the same steps from the first method to open the Change Account window.
Step 2: Click “Check Name”
In the Change Account window, click the Check Name button. Outlook will attempt to connect to the server using the name you entered. If successful, the name becomes underlined and a dialog box confirms your mailbox is found.
Step 3: Resolve Any Errors
If you see an error like “The connection to Microsoft Exchange is unavailable,” the server name is wrong or the server is down. Try the alternative methods above to find the correct name.
Using The Server Name On Mobile Devices
Now that you have the server name, you can configure Outlook on your iPhone, Android, or iPad. The process is slightly different for each platform.
For IPhone/iPad (IOS Mail App)
Go to Settings > Mail > Accounts > Add Account > Exchange. Enter your email and password. When prompted, enter the server name you found. The app will automatically detect the rest.
For Android (Gmail Or Outlook App)
Open the Outlook app. Tap Settings > Add Account > Exchange. Enter your email and password. If the server field appears, paste the name you copied. If not, the app may detect it automatically.
For Mac Mail
Open Mac Mail. Go to Mail > Preferences > Accounts > Add Account > Exchange. Enter your email and password. Mac Mail will ask for the server address. Enter it exactly as you found it.
Troubleshooting Common Issues
Even with the correct server name, you might encounter problems. Here are the most frequent issues and their fixes.
Issue 1: “Cannot Connect To The Server”
This usually means the server name is wrong or your internet is down. Double-check the spelling. Also, ensure you are using the correct port numbers (443 for HTTPS).
Issue 2: Server Name Changes Frequently
Some organizations use load balancers that rotate server names. In that case, use the generic “outlook.office365.com” instead of a specific pod address.
Issue 3: The Server Name Is Grayed Out
This happens when Outlook is configured with Autodiscover. You cannot edit it manually. Use the Outlook on the web method to find the actual server name.
Issue 4: Multiple Server Names Appear
If you see two different server names, one is for internal network and one for external. Use the external one when connecting from home or mobile.
