Outlook allows you to install plug-ins to extend the functionality of the email client. However, these plug-ins may cause problems with the application. In such cases, you need to disable the problematic plug-ins to resolve your Outlook issues. It could be possible that there is an extension that enabled your Outlook which makes you face this problem. In such cases, all you can do is to disable each extension and then try to connect. If it goes great, then it means that there is a problem with an extension(s).

Step1 Press Windows + R at the same time to open "Run".

Step2Type the following in the "Run" box and press the Enter key.

Tip 9: Rebuild Outlook Data File

Outlook saves your email data in the application's data files, and these files become corrupted or faulty, causing connection problems with the application. You can even try to rebuild the whole Outlook data file to resolve Outlook not connecting to server error. The application saves its data and info to an external file. It is a kind of storage for Outlook that it uses to perform its operations. Here, we will delete this data file.

Step1 Open the "Account Settings" in your Outlook.

Step2 Click on the "Data Files" tab and after that, choose the Email account that's causing issues. Then, tap on the "Open File Location".
