Acrobat DC - We can't verify subscription status when opening PDF from Outlook

[Wolfgang5E24]

Hi

We're experiencing the following problem. If we try to open a PDF using Acrobat DC from a Outlook mail, we're getting the error message "We can't verify your subscription status", when we save it to the computer first and open the same file from the drive, everything works fine.

Does anybody else have this problem? Or do you have any suggestions why this happens?

Thanks in advance

Additional information - if you open Acrobat before trying to open the PDF in a mail, it works.

The problem only occurs when Acrobat is closed and you're trying to open a attached PDF.
