Questions buyers ask

Does it replace Outlook or the Teams calendar?

No. Outlook and Teams stay as they are. Virto Calendar App shows them together with SharePoint lists and Planner, and edits go back to the source.

Do we have to move our events into it?

No. Events stay where they are; the app reads them there. Nothing to migrate.

Will everyone see the same events?

Everyone opens the same calendar, and each person sees what their Microsoft 365 rights allow.
