manage-category
Manage Outlook master categories: list, create, update, or delete color-coded labels used across mail, calendar, and contacts.
Instructions
Manage the user's master category list (the colour-coded labels available across mail/calendar/contacts). action=list (default) returns categories with id/displayName/color. action=create adds a new category — displayName required, color optional (preset0-preset24, e.g. preset0=Red, preset7=Blue). action=update (alias set — deprecated) changes name/colour by id. action=delete removes a category — this does NOT untag messages already labelled with it; existing messages retain the orphaned label until manually cleaned. Use apply-category to tag/untag specific messages.
