Lync Online is available in three stand-alone plans (Plan 1, Plan 2 and Plan 3) - as well as part of the Office 365 packaged plans (the P and E plans). See the below chart for more information on which Lync Online plan are included in which packaged plan

Isn't Lync with the P Plan restricted to 50 attendees max? This table gives the impression that it can have 250 attendees max? Or has that changed recently?
Is this report true?
that the maximum limit is now 1,000 attendees?
FYI: "Lync Online meeting limit increase in the works"
