Frequently Asked Questions

Why won't my PDF email attachment open on my computer?

This typically occurs because the default PDF viewer is unassigned, the file was corrupted during download, or your current PDF software requires a critical update. Setting a dedicated default PDF reader usually resolves the issue.

How do I fix the 'Attach to email' option not working in Acrobat Reader DC?

Go to Edit > Preferences > Email Accounts in Acrobat Reader DC. Ensure your default email client (such as Outlook or your preferred webmail) is correctly set up. If it is already listed, try removing and re-adding the account.

Can I open PDF attachments directly from webmail without downloading?

Yes, most modern webmail services like Gmail or Outlook on the web allow you to preview PDFs directly in the browser. However, to edit, sign, or print them accurately, you must download the file and open it with a dedicated PDF reader.

What should I do if Acrobat freezes when opening a PDF from an email?

Try disabling 'Protected Mode at startup' by navigating to Edit > Preferences > Security (Enhanced) in Acrobat. Uncheck 'Enable Protected Mode at startup'. Note that disabling this feature may reduce security, so only do this for trusted files.
