Hi @Biju Jacob ,
Welcome to our forum!
As i know, we can set the default amount of time at which you want to receive reminders before new calendar items (for example, 15 minutes, 30 minutes, etc.). Please try the following steps:
- Click File > Options > Calendar.
- Under Calendar options, select or clear Default reminders.
More information: Set reminders for all new meetings.
Hope to help you!
