Windows 10: Unable to open attachment/appointment Office Outlook/calendar

    Unable to open attachment/appointment Office Outlook/calendar

    My client has Office outlook 2007 installed on his laptop running Windows 10. Upon receipt of an email the attachment goes to his calendar. Up until 7 days ago he was able to open the attachment/appointment directly from his calendar. The attachment/appointment is a .pdf file...I clicked on the attachment and a splash screen came up telling me he had to have "outlook" installed in order to view this file. Outlook is installed on the laptop! I was unable to open the file. He has outlook installed as well as Acrobat Reader XI. I tried right clicking on the file and received negative results. The problem just began appearing this week.
    He receives emails for his job...the supervisor invites him to accept the appointment or not. He accepts the appointment but then is unable to open the appointment/attachment.
    I recommended he download MS Office 365 which is what I have done, installing it on my Windows box and my Mac Mini. Not sure how to help him at this point.
    Any help is greatly appreciated.
    Cheers and beers!!

    Hi Bill.

    SInce you have the timing so exact could you please check the Windows Update history and see what updates have been installed. Likely one for Outlook that is causing issue.

    I would also check the "Trust Center". Has been a long time since I use 2007. Click file, upper left, then options. In 2013 it is the last heading in navigation panel that opens.

    I would also check defaults app. In default apps use the option to set by app. Select Adobe and then click option to assign all possible defaults (extensions) to Adobe.
