Many Outlook users experience connectivity issues when using the program.

There can be various reasons behind Outlook disconnected issues; some of them are:-

#1. Network Issues

Connection problems, proxy or firewall settings, slow network speeds, or outdated software can prevent Outlook from establishing a stable connection.

#2. Issues with the Outlook configuration

Improper setup or corrupted files in the Outlook configuration may also cause connecting trouble.

#3. Problems with the PST files

Large-sized PST files and corrupt or incomplete emails can cause Outlook to malfunction or disconnect.

#4. Software Issues

Security patches, Windows updates, and Microsoft Office upgrades can lead to Outlook disconnects.

#5. SSL Certificate Issue

If you’re having difficulty with your Outlook email account disconnecting, there are chances that your SSL certificate might be outdated or invalid.

#6. Conflicting Antivirus Programs or Firewalls

When multiple security programs are installed on a device, they can potentially interfere with each other, causing various network connection issues.

#7. Incompatible Programs or Updates

To successfully connect your Outlook to the server, ensure you’re using the most up-to-date version of Outlook, and check if all your programs and applications are compatible with your version of Outlook.

Fortunately, the above issues can often be addressed with a few troubleshooting steps or slight changes in your Outlook settings.

Let’s now discuss some different fixes you can try out to resolve Outlook getting disconnected from service issues.

Check your Internet Connection

The first step to dealing with an Outlook issue is ensuring your internet connection is working properly. Check the settings of your router and modem, or run a speed test to ensure your internet connection is running optimally. The status of your connection needs to be connected to the internet.

Your connection must be strong enough for Outlook to stay connected. Ensure that your computer and your network are both connected and working properly. It will help you identify if there are any issues with your network settings.

Quit and Reopen Outlook

Sometimes a fresh start is all that’s needed to get things working. Give this a try – close and reopen the Outlook application. It may just do the trick and resolve your issue!

You can also try reopening Outlook in safe mode, and sometimes incompatible add-ins may cause issues in the Outlook data file leading to damaged OST.

Here are steps to follow to ensure add-ins are not creating issues:-

  • Exit Outlook

  • Remove the defective add-in from Outlook and use Outlook normally. Once a faulty add-in causing the issue is found.

If the above two solutions didn’t turn out to be beneficial, the issue might lie in proxy settings in Outlook. Disabling the proxy settings in Outlook may resolve your Outlook disconnectivity issue from the server.

Here’s how you do it:

  • Open Outlook and select the file tab in the top navigation.
  • Under the account information, select account settings > account settings.
  • Select the exchange account, and click Change.
  • In the Outlook properties window, select the connection tab and make sure that connect to Microsoft Exchange using HTTP is selected.
  • Select the exchange proxy settings.
  • Under the proxy authentication settings, select basic authentication.
  • Uncheck the box next to “On fast networks, connect using HTTP first, then connect using TCP/IP” and click OK.

After making these changes, you should now be able to reconnect your Outlook to your server.

Repair Outlook Data File

Fault in compatibility may cause a slowdown or complete discontinuation of the working of Outlook. You can also try repairing your Outlook Data File using Outlook PST repair tools to fix the issue.

Here’s how you run a repair process that may be able to fix the issue.

  • Open Outlook.
  • Click Info>Account Setting>Account Setting

  • You may receive a message that Outlook could not repair the data file. If you do, simply restart your computer and run the repair process again.

Here’s how:

  • Click on the Always use this profile option from the drop-down menu and select your new profile.
  • Select Apply, followed by OK.
  • Now quit Outlook and reopen it and start using it.

Uninstall and Reinstall Outlook

If you still have trouble with Outlook being disconnected from the server, try uninstalling and reinstalling Outlook to fix the issue. Uninstalling and reinstalling Outlook should resolve any conflicts that are causing your issue.

To uninstall and reinstall Outlook, please follow the steps outlined below:

  • Go to the “Start” menu and select “Control Panel.”
  • Click “Programs and Features”
  • Locate “Microsoft Office Outlook” in the list of installed programs.
  • Select “Uninstall” to remove Outlook from your system.
  • Once the uninstall process is complete, reboot your computer.
  • Reinstall Outlook following the on-screen instructions
  • Reboot your computer again.
  • Launch Outlook and verify if it is connected to the server

Following the steps above should help to resolve any issue you may be having with Outlook and server connections. If you continue to have issues after following these steps, you may want to contact a professional for further assistance.

Check Certificate Issues

Before attempting any troubleshooting steps, you must ensure that you do not have any certificate issues causing the disruption. A common cause of this disruption may be an outdated or invalid digital certificate that needs to be updated to allow secured communication with your mail server.

Turn Microsoft Defender Firewall OFF

<img alt="firewall" data- data-src="https://kirelos.com/wp-content/uploads/2023/03/echo/firewall.png" data- decoding="async" height="878" src="data:image/svg xml,” width=”1214″>

It is recommended that you turn off your firewall to resolve your Outlook network issues. Firewalls act as gatekeepers, restricting unwanted or potentially malicious traffic from entering your system. However, the firewall may interfere with Outlook’s connection in this case.

To disable the firewall, follow these steps:

  • Go to the Start menu.
  • Type Windows Security and select that app. Here, you should be able to turn off your firewall temporarily or for specific networks.
  • Now click on Firewall and Network Protection.
  • Tap on the private network or the network with the active label.
  • Turn off the Microsoft Defender Firewall.
  • A User Account Control tab will pop up, select Yes and move ahead.

Once disabled, restart Outlook and see if the issue has been resolved.

We recommend you exercise caution while turning off your firewall and ensure you only turn it off temporarily. Your firewall is in place to protect you, so please make sure you remember to re-enable it once your issue is resolved.

Try Disabling Offline Mode

<img alt="work-offline" data- data-src="https://kirelos.com/wp-content/uploads/2023/03/echo/work-offline.png" data- decoding="async" height="128" src="data:image/svg xml,” width=”1156″>

If you have been using the Outlook application, then it might be possible that the Offline mode settings may be enabled, which might be causing your issue. Fortunately, this issue is quite easy to fix and can be done by disabling the Offline mode settings in Outlook.

To do this:

  • Open the Outlook application
  • Select Send/Receive Tab
  • Click on the “Wok Offline” option

The Outlook application will restart automatically and will no longer be offline. It should resolve any problems you were facing with Outlook and make it run normally.

If the issue is still unresolved, contact Microsoft support and explain the issue. They will be able to help you resolve the problem.
