Suddenly when I try to use Acrobat reader (on my desktop Mac), a pop-up window requires me to sign into an old Microsoft account which is no longer active. When I try to sign in with my current Microsoft account, I get an error message and I can't go any further. However, I can't close out the error message. I have to Force Quit Acrobat. So now I can't open PDFs. Why do I now need a Microsoft sign-in? And how can I get it to recognize my current account?
Thank you for reaching out.
As you have mentioned above, opening PDF in Reader application asks for Microsoft sign in. Would you mind sharing the screenshot of the sign in screen with us?
Did you make any recent changes on the machine?
No recent changes on my machine. Here are 1) the initial sign-in message that pops up when I try to open a PDF, with sign-in to an email account that is no longer active, 2) the attempted sign-in with my active gmail account, and 3) the error message I then get. I'm not given an option to fill in the password for my active account, and I can't close the open windows. The only way I can get out is to Force Quit Adobe Acrobat.
I have received no response to the additional information I sent. My problem has not been solved!
