Hello @Dolly Sandesara
Welcome to Q&A forum!
You can adjust your working hours in the Outlook settings to include your holiday as well. What I mean is that you should set the start and end times of your working hours (as shown in my image), instead of keeping the default schedule from 8 AM to 5 PM.
You can do this by going to:
- Settings -> Calendar -> Work hours and location
For your reference: Employee working hours - Microsoft Bookings | Microsoft Learn
Even though I’ve tried to make this as close as possible to your experience, we may be in different testing environments, and I might not fully understand your needs. Please feel free to contact me again if you still have any concerns.
