  2. Download the latest Microsoft Outlook or click update.

Fix 2: Log Out Of Outlook

On the same note, sometimes restarting Outlook helps so attempt this if you are not yet successful.

Fix 3: Change Microsoft Trust Center Settings

For some outlook editions including Outlook 2016, the fault is with wrong trust center settings.

You thus need to edit the Trust center settings for all Microsoft products you typically use to open your outlook meeting attachments including Microsoft Word and Excel:

  1. Open outlook.
  2. Go to File.
  3. Click Options.
  4. Select Trust Center.
  5. Now click the Trust Center Settings tab.

Fix 4: Ensure the relevant opening programs have been installed

The applicable attachment opening application needs to be available on your computer to access any attached files. For example, a PDF attachment won’t open if a relevant PDF reader is not installed.

Users thus need to confirm that the required file opening programs exist in their PCs.
