Correct an event sequence's scheduled date

Open Events → Events → select your event → Edit Event → Sequences.

In the sequence interface, the pencil opens editing when the user has update permission and the outreach has not already been sent. Invitations use a date/time in the event's time zone; reminders and follow-ups use timing relative to the event start/end. Update the timing and continue to the message editor. The server rejects a supplied scheduled time less than one hour in the future, including a copied date in the past. Setting a date alone does not enable sending: check the scheduling toggle in the sequence list. A disabled edit button for a sent message or missing permission is distinct from invalid timing. Inspect the actual copied sequence before identifying its specific failure.

Role for event sequences

Events Communication Admin, Events Superadmin, and Superadmin include the event-editing and event-communication capabilities needed to manage event sequences. Advanced Events Admin or Basic Events Admin alone is not enough. For a colleague who already has an event-editing role, add Events Communication Admin through Events → Administrators → select the person → Role(s) → Add Another → Update Role(s) and retain access to the intended event. Roles are predefined; do not try to turn on an individual sequence permission.
