updating / deleting categories automatically change event's category??

공민혁 60 Reputation points


I would like to inquire about the behavior of the following APIs in Microsoft Graph:

PATCH /users/{id|userPrincipalName}/outlook/masterCategories/{id}

Delete /users/{id|userPrincipalName}/outlook/masterCategories/{id}

If some events have a category that will be changed or deleted,

will these APIs apply the changes to the categories in the events?

Thank you for your assistance.

    Hi @공민혁

    After testing, if the categories that have been applied to the event are changed, the categories on the event are also changed.

    For example, if the color of a category is changed, the color applied to that category is updated on all events.

    If a category is deleted, that category disappears on all events.

    Hope this helps.
