    Hi @nrjnablasol,

     

    Can you still double check if the account you are using in the connection of the trigger action is booking admin?

     

    Btw, you can also contact Microsoft support in parallel to this thread. They might be able to help you out as well.

    (Especially if it has worked before with the same mailbox and the same account, and you are sure you still have enough booking permissions).

    Hi @nrjnablasol,

     

    Just to double check. Are you Booking admin of the calendar you are trying to use?

     

    I believe this is listed as one of the know issues/limitations when using an appointment trigger type of action:
