Outlook calendar errors no longer cause double-bookings

May 27, 2026

You can now rely on Zeeg to handle Microsoft calendar errors gracefully — protecting your schedule even when Outlook is temporarily unreachable.

What's new:

Fail-closed availability – When Zeeg can't read a host's Outlook calendar (due to rate limits, timeouts, or access errors), that host is treated as unavailable and no booking slots are offered, preventing double-bookings.

Meeting room protection – The same logic applies to room calendars: a room whose calendar can't be read is treated as busy, not free.

No false disconnects – Losing access to a single shared or delegated calendar no longer disconnects the host's entire Outlook connection or sends them a misleading "please reconnect" email.

Round-robin aware – In round-robin event types, only the affected host is blocked; other hosts with accessible calendars remain bookable as normal.

Why this matters: A temporary Microsoft hiccup shouldn't mean missed meetings or confused hosts. These changes ensure that calendar errors fail safely — no phantom slots, no unnecessary alerts, and no disruption for the rest of your team.
