When Microsoft Outlook fails to connect to your email server, you stop getting incoming emails and can’t send new emails from your end. This situation prevents you from performing any email-related tasks. Luckily, there are ways to get around this issue.

Some of the reasons Outlook experiences issues connecting to the email server include a minor glitch with the app, your internet connection isn’t working, or the Outlook data file has a problem. This guide will offer a few solutions so your Outlook client can connect to your email server and fetch new emails.

Restart Outlook

One way to fix most minor glitches with Outlook is to restart the app. When you do this, Outlook turns off all features and restarts them again. This gives each option a fresh start, fixing many minor problems.

You don’t lose your saved work when you restart the Outlook app.

  • Select File in Outlook’s top-left corner. Choose Exit from the sidebar on the left.Reopen the Outlook app.

Check Your Internet Connection

A possible reason Outlook can’t connect to your email server is that your internet connection has problems. As a result, any apps that rely on connecting to the internet will also not function.

A quick way to check if your network connection is working is by opening a web browser on your device and launching a site like Google. If the site loads, your connection is working.

If the site fails to load, you have a connection problem. You can either fix this yourself or seek the help of your internet service provider.

Fix Outlook by Disabling Offline Mode

Outlook offers an offline mode that you can use to work on your emails while being disconnected from the internet. However, if you’ve enabled this mode, that may be why the app fails to connect to your email server.

In this case, turn off the offline mode, and Outlook will be back online.

  • Open Outlook on your computer. Select the Send/Receive tab at the top. Choose the Work Offline option.The Work Offline button won’t be shaded anymore, which indicates the feature is turned off.
