In this guide, we’ll dive into five practical strategies to fix the Outlook Out of Memory error, ensuring you can get back to your emails without the hassle! 💪

Understanding the Outlook Out of Memory Error

The "Out of Memory" error typically occurs when Outlook runs out of memory to allocate for new tasks. This may be due to various reasons such as large attachments, many open email threads, or even a corrupted Outlook profile. The good news is that there are several solutions available to resolve this issue.

1. Clear the Outlook Cache

One of the first steps you can take to resolve the memory issue is clearing the Outlook cache. This can help free up space and improve performance.

How to Clear the Outlook Cache:

• Close Outlook: Ensure Outlook is not running.

• Open the Run dialog box: Press Windows + R.

• Type the following command and hit Enter:

  %localappdata%\Microsoft\Outlook
  

• Locate the cache files: Delete the files in this folder.

This action will delete temporary files that can sometimes cause conflicts.

2. Reduce PST File Size

A large PST file can consume significant memory resources, potentially leading to the Out of Memory error. Keeping your PST file under control is crucial.

Steps to Reduce PST File Size:

• Open Outlook: Launch the application.

• Archive Old Emails:

  • Go to File > Info > Tools > Clean Up Old Items.
  • Follow the prompts to archive old emails that are not needed daily.

• Delete Unwanted Emails:

  • Sort your inbox and identify large emails or unnecessary conversations.
  • Delete or move them to folders.

• Compact the PST file:

  • Go to File > Account Settings > Account Settings.
  • Click on the Data Files tab, select your PST file, then click Settings.
  • Under the General tab, click Compact Now.

By reducing the size of your PST file, you’ll be freeing up memory and potentially eliminating the error!

How to Disable Add-Ins:

• Open Outlook.
• Go to File > Options > Add-Ins.
• At the bottom of the window, manage COM Add-ins and click Go.

• Close Outlook.
• Open the Control Panel: Go to your Windows Start menu and search for Control Panel.
• Select Programs > Programs and Features.
• Find Microsoft Office in the list: Right-click it and choose Change.
• Select Repair: You will be presented with two options - Quick Repair or Online Repair.

1. Locate the Registry Editor:

   • Press Windows + R, type regedit, and hit Enter.

2. Navigate to the following path:

   HKEY_CURRENT_USER\Software\Microsoft\Office\\Outlook\Options
   

   Replace <Your Office Version> with the correct version (e.g., 16.0 for Office 2016).

3. Right-click on the Options folder: Choose New > DWORD (32-bit) Value.

4. Name it "MaxFileSize" and set the value according to your needs.

Note: Editing the registry can be risky; ensure you take appropriate precautions or consult a professional.
