Microsoft and Adobe are separate software companies. AFAIK, MS Office 365 does not include any Adobe products like Photoshop, Illustrator, InDesign, etc... Those are by separate subscription to an Adobe Creative Cloud Plan.
If you're actually asking about Adobe Acrobat (for PDF), there are 2 versions available below.
Hope that helps.
