Microsoft Outlook is one of the most popular mail programs, and Microsoft Exchange is used not only by many Fortune 500 companies but, by small businesses alike.
If a service like Exchange has a connection issue, then communication would be highly compromised.
Have you been disconnected from Outlook? Are you in search of a solution to this issue?
If so, you are in the right place. In this article, I’m going to show you the 7 surefire methods to resolve the issue of Microsoft Outlook showing disconnected.
BUT, before I dive into this article, here’s a short video that will also help provide some initial insight into what could be causing your Outlook disconnected problem, and the balance of this article dives into the technical specifics in more detail – especially method 7 listed below (which is somewhat more technical. This is the one I used to resolve my issue). You can watch the first 60-seconds of this short video here first:
How to Resolve Microsoft Outlook “Disconnected” Issue
Microsoft Outlook is such an important application for many organizations that if it stops working, then the impact will be felt by the whole business, and when it happens, you get the “oh no, panic, Outlook Disconnected” feeling.
Many companies’ communication is highly reliant on Outlook’s service. Sometimes, Outlook fails to work due to connectivity issues. In this instance, it can cause chaos in an organization because it gets difficult for employees to proceed with work.
Outlook is the most efficient, quick, and cost-effective application which should always be in an active and running state.
Sometimes the Outlook application may display a typical issue that shows an alert message stating, “Microsoft Outlook is disconnected.” This is a common error that will stop you from sending or receiving emails to or from clients. By following the simple steps given below, you can easily resolve this issue and continue your work. Here’s what you can do:
Method 1: Restart your PC when Outlook is Showing Disconnected
The ‘Disconnected’ error typically occurs all of a sudden, and you can first try to resolve it by restarting your PC (and there could be an IP issue conflict – see method 6 below). This is the main thing you should do if you get this error while working on Outlook.
Once you restart your system, launch the Outlook app. It might start normally and if it does, you can go ahead with your work.
Method 2: Ping the Server
If you get the same error after restarting your PC, you should try to ping the server. Ping is a utility or a command within an operating system that can help determine whether the issue is related to the server/host or not. Ping can be used to check the network connectivity and the speed among the two networks. One network is yours and the other is hosted on the internet. In such a case, you can ping the exchange server for which you need to have the server name. Once you get this, follow the steps below:
- Firstly, go to Start and access the Run function on your PC.
- Type CMD and click “OK”.
- A command prompt window should pop up on the screen.
- Type a command in this format: “Ping” + name of the Exchange server.
- The ‘ping’ utility will run for a few seconds and display the results in the form of Responses.
- If you receive a response saying “Request timed out”, it shows that the issue is related to network connectivity or the exchange server.
- In order to fix this issue, you need to contact a server’s team.
- If the responses are summed up with some packets as Sent = 4, Received = 4, Lost = 0″, this means that there is no issue regarding the server or network connectivity so that you can skip the step of checking the LAN cable, network connectivity, etc.
Method 3: Check Active Directory (LAN) Account Password Settings – Microsoft Outlook
Firstly, ensure that your Microsoft Outlook account is still functional. For that, you need to check your Active Directory (LAN) account password settings. Through this method, you can make sure that your account hasn’t expired or been suspended.
- Check with the Domain account whether it is locked or the password has expired.
- If your client agrees to do a password reset for Domain, then go for it.
- Now, you need to access the active directory and then click on Users.
- Just scroll down to the particular user whose password you want to reset.
- Select the user and Click on the Reset Password option.
- Enter the new password and confirm it by re-entering the same.
Method 4: Check if the Program is in Offline Mode
It is common that Microsoft Outlook may go into the offline mode unintentionally or due to some change in your location’s network connection. You may have forgotten to enable the online mode on it. So first, check if the Outlook is in Offline mode. To change the settings, simply follow the steps below:
- Firstly, open the Outlook application.
- Scroll down to the bottom right corner of the Outlook window and click on the “Disconnected” message that appears on the screen.
- A context menu list appears and you can see a checkbox that shows offline mode.
- If the ‘Work Offline’ option is checked, click to uncheck it and turn it to Online. This should solve your problem immediately.
- If you are still unable to find the checkbox selected, select and deselect it again which should help resolve the issue.
Method 5: Start the application in a Safe Mode
If you fail to resolve the issue even after trying all the above methods, start the application in a safe mode. Follow the steps:
- Go to the Start menu and access the Run program.
- In the Run dialog box, type “outlook.exe/safe” and then click OK.
- If there is any issue due to the installed add-ons, then try to disable all the unnecessary and redundant add-ons.
- Again, restart the application and check if the issue is resolved.
These are various methods that will help you in resolving the disconnection issue in the Microsoft Outlook application so that you can carry on with business as usual. I hope this simple guide assists you in the best way to rectify your Microsoft Outlook disconnection issue!

Method 6: Outlook Showing Disconnected – Try Disabling IPv6
If all else fails (from the 5 methods above), you can always try disabling IPv6, and note – this tip is for the more technical amoung us, and if that’s not you, then be sure to check with the IT department before you do what I am about to suggest.
It’s possible that Outlook 2013 2016, Outlook 2019, or Outlook 365 can lose their connection to the Office 365 hosted Exchange mailbox – I’ve had to address this quite a few times in the last year, and in most of those cases, this has been the problem.
You can try to disable IPv6 on the network adapter that handles the internet connection. To do this, go to the “Network and Sharing Center”, and then change adapter settings. Note, you will need to right click on the adapter under Properties, and there’s a box by the Internet protocol (TCP/IPv6). You can try unchecking that box, restarting the computer. It’s quite possible that when it’s finished rebooting, you will notice that Outlook 2019 will reconnect.
What is IPv6?
There are 2 common internet protocols, IPv4, and IPv6. It so happens that ARIN, the registry that assigns IP address, has run out of IPv4 addresses, so a number of years ago, they created a new IP addressing scheme – called IPv6, which opens up an almost infinite number of IP addresses. You will notice IPv4 looks like this (for example): 192.168.0.1. On some occasions, IPV4 and IPv6 don’t play well together.
Method 7: Corrupt Outlook Profile
It’s possible that your Outlook profile is corrupt, and that might cause Outlook to no longer remember your password. You can try to create a new mail profile which can be done in the Control Panel, at which point you will reconfigure your email account in the new profile. To create a new profile, you can reference the following Microsoft support article: Create an Outlook profile
