You can manage your meetings at any time from the My Meetings section of your Solarplaza account dashboard. There you can see your upcoming and pending meetings, accept or decline invitations, cancel a meeting, or propose a new time for an existing one. Cancelling a booked meeting frees up that time slot again, so the room becomes available for other bookings.
There is no fixed “availability calendar” to set, time slots that are already taken by your other meetings are automatically marked as unavailable, which prevents double-booking. If you need to step away from the meeting tool entirely, you can also adjust your visibility from Personal Information (Your Solarplaza Profile) section of your Solarplaza account dashboard.
