Outlook’s preview pane is one of its most beloved features, allowing users to quickly scan email content without having to open each individual message. But what happens when this feature suddenly stops working? The frustration is palpable, and the search for a solution can be overwhelming. If you’re stuck in this predicament, wondering why your Outlook preview is not working, you’re not alone. In this comprehensive guide, we’ll delve into the possible reasons behind this issue and provide you with actionable steps to troubleshoot and repair your Outlook preview pane.
Reason 1: Corrupted Or Damaged PST File
A corrupted or damaged PST (Personal Storage Table) file is one of the most common culprits behind a non-functional preview pane. PST files are responsible for storing Outlook data, including emails, contacts, and calendar events. When a PST file becomes corrupted, it can lead to a range of issues, including a malfunctioning preview pane.
To troubleshoot this possibility, try the following steps:
Step 1: Run the Inbox Repair Tool
The Inbox Repair Tool, also known as SCANPST.EXE, is a built-in Outlook utility designed to repair damaged PST files. To run the tool:
- Close Outlook and navigate to the following location:
C:\Program Files\Microsoft Office\root\Office16 - Double-click on SCANPST.EXE to launch the tool
- Select the PST file you want to repair and click Start
Step 2: Check for PST File Size Limitations
PST files have size limitations, and if your file exceeds these limits, it can become corrupted. To check the size of your PST file:
- Open Outlook and click on File > Account Settings > Account Settings
- Click on the Data Files tab and note the size of your PST file
If your PST file is approaching the maximum size limit (2 GB for ANSI PST files or 50 GB for Unicode PST files), consider creating a new PST file or archiving old emails to reduce the file size.
Reason 1.1: PST File Fragmentation
PST file fragmentation is a common issue that can arise when Outlook is frequently shut down or crashed. When this happens, the PST file becomes fragmented, leading to performance issues and a malfunctioning preview pane.
To defragment your PST file:
- Close Outlook and navigate to the following location:
C:\Program Files\Microsoft Office\root\Office16 - Double-click on SCANPST.EXE to launch the tool
- Select the PST file you want to defragment and click Start
- Follow the prompts to complete the defragmentation process
Reason 2: Add-in Conflicts
Add-ins are third-party applications that integrate with Outlook to provide additional functionality. While add-ins can enhance your Outlook experience, they can sometimes conflict with the preview pane, causing it to malfunction.
To troubleshoot this possibility, try the following steps:
Step 1: Disable All Add-ins
- Open Outlook and click on File > Options > Add-ins
- Click on the Go button at the bottom of the window
- Uncheck the box next to each add-in to disable them
Step 2: Enable Add-ins One by One
- Re-enable each add-in one by one, restarting Outlook after each addition
- Check if the preview pane starts working after enabling each add-in
This process will help you identify which add-in is causing the conflict.
Reason 2.1: Problematic Add-ins
Some add-ins are notorious for causing issues with the preview pane. If you’re using any of the following add-ins, try disabling them or seeking alternative solutions:
- Skype Meeting Add-in: This add-in is known to cause issues with the preview pane. Try disabling it or updating to the latest version.
- Microsoft Teams Add-in: Similar to the Skype Meeting Add-in, the Microsoft Teams Add-in can cause conflicts with the preview pane. Try disabling it or seeking alternative solutions.
Reason 3: Outlook Configuration Issues
Sometimes, Outlook configuration issues can cause the preview pane to malfunction. To troubleshoot this possibility, try the following steps:
Step 1: Reset Outlook Settings
- Open Outlook and click on File > Options > Advanced
- Click on the Reset button at the bottom of the window
- Restart Outlook
This will reset Outlook to its default settings, which may resolve the issue.
Step 2: Check for Mailbox Configuration Issues
- Open Outlook and click on File > Account Settings > Account Settings
- Check if your mailbox is configured correctly
- Ensure that the Outlook profile is set up correctly and that the mail server settings are accurate
Reason 3.1: Cache And Cookie Issues
Outlook’s cache and cookies can sometimes become corrupted, leading to issues with the preview pane. To troubleshoot this possibility, try the following steps:
- Close Outlook and navigate to the following location:
%localappdata%\Microsoft\Outlook - Delete the
Outlook.xmlfile and restart Outlook
This will clear Outlook’s cache and cookies, which may resolve the issue.
Reason 4: Operating System And Software Conflicts
In some cases, operating system or software conflicts can cause the preview pane to malfunction.
To troubleshoot this possibility, try the following steps:
Step 1: Check for Windows Updates
- Ensure that your operating system is up-to-date by checking for Windows updates
- Install any pending updates and restart your system
Step 2: Check for Conflicting Software
- Check if any recently installed software is conflicting with Outlook
- Try uninstalling any recently installed software and restarting Outlook
Reason 4.1: Antivirus Software Conflicts
Antivirus software can sometimes conflict with Outlook, causing issues with the preview pane. To troubleshoot this possibility, try the following steps:
- Check if your antivirus software is set to scan Outlook files
- Exempt Outlook from the antivirus software’s scan or adjust the software’s settings to avoid conflicts
Reason 5: Network Connectivity Issues
Network connectivity issues can cause the preview pane to malfunction.
To troubleshoot this possibility, try the following steps:
Step 1: Check Network Connectivity
- Ensure that your network connection is stable and working correctly
- Try restarting your router or modem if you’re experiencing connectivity issues
Step 2: Check for Proxy Server Issues
- Check if your organization is using a proxy server
- Ensure that the proxy server settings are configured correctly in Outlook
