Set calendar permissions

Make my executive assistant, Priya Singh, a delegate on my calendar with permission to view details and create events, but not delete recurring series. After setting that, send Priya a calendar note explaining which event types she may edit and ask her to test by creating a mock 30-minute booking next Tuesday at 10am. Confirm by end of day today.

Before I set Priya as a calendar delegate, make the request easy for her and for our legal reviewer. Put the permission level up front (Can view all details, create and edit events, cannot delete recurring series), flag entries that would cause hesitation (board meetings, attorney notes, personal doctor appointments), and suggest one-line guidance to include in the permissions email so she knows how to handle sensitive events.

I just gave Priya edit rights and she unintentionally deleted our monthly board-prep series while cleaning duplicates. I didn't keep a separate master calendar and I can't reconstruct every invite. I can't tell whether the series is recoverable or who will notice first. What is the most likely recovery path and the immediate communication I should send to limit blame and restore the series quickly?

Delegates keep moving or deleting recurring events and it creates last-minute chaos for the exec team. Am I failing at how I assign permissions, label events, or train delegates? Recommend one habit and a tiny change to our calendar naming or permissions that will prevent accidental edits going forward.
