EVERYTIME I OPEN A PDF FILE ITS PROMPT ME

Hi,

The prompt that you’re getting may appear if the default app to open a PDF file isn’t set yet. For us to learn more about your concern, we’d like to ask the following:

• Which version of Outlook that’s installed on your computer?  Please check this article for the steps to know this information.
• May we ask for a screenshot of the actual prompt or message that you’re getting when you’ve opened a PDF file attachment?
• Have you already tried setting up the default app to be used when viewing or opening a PDF file? If you haven’t done it yet, you may navigate to Settings > Systems > Default apps > Choose default apps by file type, then look for .pdf file and select the application that you wanted to use.
  
  
  
  
  

We’ll wait for your response.

I have 6 new pc's with the same issue.

Office installed last week from office 365 portal.

Acrobat installed direct from adobe.

pdf files open fine from explorer.

when opening from Outlook it prompts "how do you want to open this file"

i have checked the always use this app button each time.

i tried with both Acrobat and Acrobat reader.

i ran outlook as administrator.

i ran a repair on office. 

windows updates are current.

how can i get outlook to open PDF's without prompting?

I have the exact same problem. I've gone to the default settings and have made sure the default is set.  I am also on a brand new computer (1 week old). I had a Microsoft 365 Office 2016 subscription that validated when I started up the computer so I don't think I'm running from a trial, ( didn't chose that option when I set the computer up). How can you tell if its reading this as a trial?

I open at minimum 40 .pdfs a day from outlook and this is driving me nuts!

Mine was originally a new install on new computers.

The solution for me was to reinstall Office.

Microsoft must have temporarily had a bad install posted.

reinstalling fixed the problem all my computers.

Hi,

It is possible that there is no application that is set up as the default program to open your PDF files. We recommend that you access the Apps page under Settings to set up the which application will be used when opening PDF files. To do this, follow the steps here.

Let us know how it goes.

I did configure what app to use for PDF files.

It worked fine except in Outlook.

The solution was to completely remove office and reinstall it.

Repairing or installing over the top didn't work, uninstall first.

I had 6 problem computers and reinstalling fixed all of them.
