Outlook Not Working? Complete Troubleshooting Guide

Are you facing issues with Microsoft Outlook? Email problems can disrupt your workflow.
This guide will help you fix common Outlook issues quickly.

Identifying Your Outlook Version

Before starting, determine which Outlook version you’re using. Microsoft offers two
versions with different troubleshooting approaches.

To identify your version, check for the File option:

• No File option? You’re using New Outlook
• File option visible? You’re using Classic Outlook

Most users have Classic Outlook, which we’ll focus on here. For New Outlook issues, check Microsoft’s support pages.

Step-by-Step Troubleshooting Guide

3. Select Office Account or Account
4. Click Update Options
5. Select Update Now

2. Start Outlook in Safe Mode

Safe Mode launches Outlook without add-ins. This helps identify if an add-in is causing problems.

3. Press Enter

Method 2: Using Ctrl Key

1. Hold the Ctrl key

3. Disable add-ins one by one, restarting Outlook each time

3. Check for Frozen Processes

Outlook may appear running but become unresponsive. Here’s how to check:

1. Click different elements in the window
2. Try keyboard shortcuts
3. Look for “Not Responding” in the title bar

If frozen, end the process and restart Outlook.

4. Check for Multiple Outlook Processes

Multiple Outlook instances can cause conflicts and slow performance.

To fix this:

1. Press Ctrl + Shift + Esc for Task Manager
2. Find multiple OUTLOOK.EXE entries
3. Select each extra process
4. Click End task, leaving only one running

1. Close Outlook completely

3. Run SCANPST.EXE
