Hi @Deni Garo
You could take a reference at the method introduced in this similar question: How to auto respond/ auto decline meetings outside work hours
1.Creating a nonexistent event during your off-duty time in your Outlook calendar, and set it recurring:
Open the Outlook client > switch to calendar page by clicking the Calendar icon at the left bottom corner > Home > New Meeting > click Make Recurring and set the recurrence pattern, OK > complete creating meeting, click Send.
2.Open the Automatic decline option in Outlook.
File > Options > Calendar > Automatic accept or decline > select Automatically decline meeting requests that conflict with an existing appointment or meeting (NOTE: you need to select Automatically accept meeting requests and remove canceled meetings at the same time) > OK.
