# Meetings and calendar invitations

> Send invitations that show Accept and Decline, and keep your connected calendar out of your booking availability.

Google and Microsoft 365 calendars connect with the same sign-in as the mailbox — one sign-in covers both. Apple iCloud, Yahoo and any other CalDAV server use an app-specific password.

**Invitations** go out as a proper calendar part, which is what makes a mail client show Accept and Decline rather than an unremarkable attachment. Rescheduling sends an update that actually moves the meeting in everybody's diary rather than arriving as a duplicate.

**A connected calendar blocks time.** Meetings already in your diary are read in and stop those slots being offered on your booking pages. An event marked free does not block anything — that is what "free" means, and treating it as busy would hide availability you actually have.

Use **Sync now** on a calendar to pull in changes immediately rather than waiting for the next scheduled sync.
