PDF file extension changes to PD file extension in Outlook email fault
Running Windows 10 on PC, I use the web browser to access Outlook email.
When sending attachments via Outlook email I've just started seeing the first pdf file attachment changing to a PD file extension (blue), whilst the others stay the same, a pdf . The recipient can't view the file when opening it to view, as its a PD extension, however when they save the file then open it works fine, and similarly on my PC. If I delete the first file, the pd, the rest stay as pdf files, as they were originally.
I have re-installed Adobe Acrobat reader, no change with the fault, and have also uninstalled Acrobat and installed Adobe Pro, same issue.
Tried using Windows 10 email and pdf files show as normal.
Windows says its an adobe issue.
Any help on this would be great as Clients are complaining.
