Normally, you can contact the Email Technical Support staff for assistance, but what if you are at home and unable to contact them? To begin, do not panic! Second, explore with the numerous techniques for troubleshooting described below. Now test Outlook’s connection to the Exchange Server. Let’s get started!

Outlook Cannot Connect to Server Troubleshooting Guides
The following step-by-step solutions efficiently resolve your Outlook Cannot Connect to Server issue. We’ll begin with the easiest way and gradually increase the difficulty level one by one. Follow the instructions below to resolve the server connectivity issue:
Method 1: Uncheck the Offline Mode box.
When a Outlook user call to customer care and said, “My email is not working!” This indicates that Outlook is in some way configured to Offline Mode. If you are currently using Outlook 2007 or a previous version, simply navigate to the “File” menu and tick the box next to Work Offline and uncheck it immediately, and you should be ready to go.
If you are using Outlook 2010 or a later version, the following steps must be taken:
• Select the “Send/Receive” option.
• Locate the “Work Offline” button.
• Then press the “Offline” button.
Now, at the bottom of your Outlook window, you should see something like ‘Trying to Connect…’ If it connects, your connectivity problem is resolved.
Method No. 2: Restart Outlook
Many frequent Outlook problems can be resolved simply by quitting and restarting Outlook. As a result, we advise you to restart MS Outlook first, and if it does not resolve Outlook Cannot Connect to Server, then restart your computer system as well. The problem could be caused by a connectivity malfunction on the PC. If you open your web browser and are unable to access a website or internal resources, the problem is most likely with the computer system.
Method No 3: Rebuild Data Files
Outlook works with two types of data files:.pst and.ost. Both file types are vulnerable to flaws that could result in an Outlook Connectivity Server Problem. First, go through the following procedures to check whether you can reconnect:
- First, exit Outlook.
- To open the Control Panel on Windows, click the “Start” icon and select “Control Panel.”
- Look for the “Mail” icon and touch on it.
- Click “Data Files” in the next window.
- Locate the file that has the same name as your email address.
- Select the “Open File Location…” tab.
- If your file is an.ost file, right-click it and rename the extension to.OLD. Do not make any changes to your.pst file just yet.
- Close all currently open windows and reopen Outlook.
Outlook will begin the process of re-creating your data file. Depending on the number of Outlook files you have, this could take anywhere from 10 minutes to more than an hour. Make sure you don’t close Outlook while this is happening!
When it’s finished, a notification saying “All folders are up to date” will appear on the screen.
If you do not have an.ost data file but rather a.pst file, then proceed as follows:
- In the file explorer, navigate to C:Program Files or C:Program Files (x86).
- In the search box, type scanpst.exe.
- To run the application, double-click on the file.
- Your default.pst or.ost file should be already selected.
- Start by clicking the Start button.
Scanpst will perform several scans on the data file, which will take time to finish depending on the size of the data file. If it detects mistakes in the data file, it will prompt you to repair it by clicking the Repair button. When this occurs, you should additionally tick the option labeled “Make Backup of Scanned File Before Repairing.” Once this is done and the repair is finished, you can reopen Outlook and look for the connectivity error.
Method 4: Restore the Office Installation
Another option for resolving the Outlook Cannot Connect to Server problem is to repair the Microsoft Office installation. Here are the instructions you must follow:
- Navigate to the Control Panel.
- Navigate to the “Programs and Features” menu.
- Locate and pick the Microsoft Office installation.
- Select “Change” from the context menu when you right-click on it.
- From the resulting window, select Repair.
- Continue by clicking the button.
- Allow the repair to be finished.
- After the fix, restart your computer.
After restarting your computer, open Outlook and verify that the connection failed to connect to the server issue has been repaired. If it is not connecting, move on to the next technique.
Method 5: Create a New Profile
When all else fails to resolve the Outlook Cannot Connect to Server issue, the final option is to recreate your MS Outlook profile. It is recommended that you create a new profile without deleting the old one. You must know your account settings in order to reconstruct your profile, so have that information ready before you begin. Here’s how you may make a new profile:
- Navigate to the Control Panel.
- Check Your Email
- Select Show Profiles.
- Add a new item.
- Mention a specific name in the profile.
- Work your way through the Outlook account setup wizard.
- Once the profile has been proven to work, you should either set it as the default or delete the old profile.
