How can I fix PDF attachment issues in Outlook?

1. Use a PDF reader

If you don’t already have PDF reader software installed on your computer, you might not be able to open a PDF file in Microsoft Outlook directly.

Please use the top PDF reader software currently on the market. Make sure Adobe Reader is present.

It’s also a good idea to have the most recent version, so download it immediately, install it, and then try opening the PDF documents again.

2. Scan the PDF

    1. Enter Windows Defender after typing it into Start.
    2. Choose the custom scan option, then choose the PDF file folder.
    3. To continue, click scan at this time.

If a PDF file doesn’t open in Outlook, you should scan it to see if your Windows PC can open it safely.

Make sure to scan any PDF files you get over email because some of them may include malware, spyware, or viruses that could pose a harm to your computer.

As an alternative, you can perform a scan of the PDF file by choosing from the options when you right-click on it.

3. Restart Microsoft Outlook

It’s possible that Microsoft Outlook was overloaded when you attempted to open the file; as a result, you might think about restarting Outlook and trying again.

Additionally, ensure your Internet connection is working properly so you can fully download the PDF documents and examine them in the previewer menu.

This small workaround may be helpful if Outlook won’t open PDF attachments.

4. Run Windows Update

    1. Enter Windows Update in the Start search box and then click OK.
    2. Click the Check for updates button in the Windows Update window.

Microsoft often releases patches that include drivers and bug fixes for your Windows computer. Therefore, make sure your machine is running the most recent OS version.

If Outlook doesn’t open a PDF file, this could help you and maintain your computer free of bugs.

5. Request for a resend

If the PDF file was transferred using a USB, it could occasionally have been corrupted. Additionally, the PDF file was not perfectly created by the tool that was used to make it.

However, you might need to request a different format or ask the sender to deliver the PDF file to you again.

6. Use the right password

A password is used to encrypt some PDF files, protecting them from unauthorised access. For instance, bank statements, receipts for payments, private documents, etc.

You must enter the correct password, which is secure and can only be known by the relevant person, in order to open this collection of files.

Solution 7: Temporarily disable the antivirus protection

    1. Launch your antivirus programme and temporarily disable the protection.
    2. Open Microsoft Outlook at this time to see the PDF attachments.

Antivirus software occasionally has the ability to destroy or quarantine specific program-related files, patches, or DLLs.

However, the antivirus scanning algorithms may mistakenly associate trustworthy files with potentially dangerous ones.

Disabling your antivirus programme may be helpful if Outlook won’t open PDF attachments.
