Invites I receive from a comcast.net user. When I open the invite, I cannot find any option to accept the invite. I also have a comcast.net email address. What seems odd is that when I open the invite in my iPhone, there is a way to accept.

    Known "regression". i.e. New Outlook for Windows no longer processes Meeting Invites for non-Microsoft email accounts (e.g. GMail, Yahoo, Comcast)

    recently there was an update to the New Outlook for Windows that changed how it interprets iCalendar (ICS) invitations for non-Microsoft accounts (like Gmail, IMAP, Yahoo, etc.), ... related to the buttons disappearing. This actually is a known regression and has been reported to feedback hubs already.

    In Outlook on Windows (including the new Outlook for Windows), the ability to accept or decline an invitation depends on Outlook recognizing the message as a meeting request. When the sender is using a non‑Microsoft service such as Comcast, the invite sometimes arrives as a regular email (or with malformed calendar data), so Outlook does not show the Accept/Tentative/Decline buttons, even though iOS Mail or Outlook mobile may still interpret it as a calendar event.

    Because the message is not being treated as a proper Outlook meeting request on Windows, there is no way in Outlook for Windows to surface the standard Accept/Decline options for that specific invite. The practical workarounds are:

    1. Use Outlook on iOS/Android to accept the invite, where the RSVP options appear correctly.
    2. Manually create a new appointment/meeting in Outlook on Windows at the same date/time as the invite and track it that way.
    3. Ask the sender to resend the invitation from a service that generates standard Outlook/Exchange‑compatible meeting requests (for example, Outlook.com, Microsoft 365, or another Exchange‑based account), which will then show Accept/Tentative/Decline in Outlook on Windows.

    On mobile, Outlook for iOS explicitly supports quick RSVP actions when the invite is recognized as a meeting:

    1. Next to the invite, tap RSVP.
    2. Review the time on the calendar and tap Accept, Tentative, or Decline.

    This explains why the iPhone view offers RSVP options while the new Outlook for Windows does not for the same Comcast‑originated message.
