Ways to Fix Unable to Open Attachments issue in Microsoft Outlook on Windows

Run Microsoft Outlook in Safe Mode

Launch Outlook in safe mode to begin the fix. Then it will function without the integrated add-ins you have used, but you may need to uninstall some add-ins to get it back to normal.

If you are using Outlook in safe mode, attachments should be accessible. The first step is to disable all of your add-ins. After that, you can re-enable them one at a time and try to open an attachment again. Here’s how to do it:

  1. First, disable all of your add-ins.
  2. Next, try to open an attachment again. If the attachment is not accessible, then the add-in that is causing the problem is likely the one that you disabled in step 1. Try disabling that add-in again and see if the attachment becomes accessible this time around. If it still isn’t accessible, then there may be another add-in causing the issue which you will need to identify and disable. ..

Check if the File in the Attachment is Corrupt

It is possible that the file that Outlook sent you is damaged. If you attempt to open it, Outlook will alert you to the corrupt file. Inform the sender of the problem and instruct them to send the file again via Outlook.

Disable the Anti-Virus Program Temporarily

Although it may seem like an inconvenience, turning off your antivirus programme before opening attachments sent to you can help protect yourself from potential harm.

Be cautious when receiving emails, as spammers may try to send you malicious links. Do not open attachments from unknown senders unless you are sure of who they are. ..

Update Windows OS

If you’re having trouble opening the link in Outlook, be sure to upgrade your Windows OS to the most recent version. This should resolve any issues. ..

Enable Outlook Attachment File Preview

If you are unable to open an attachment delivered to you via Outlook, is the attachment preview turned on?
