Locking Details in Calendar App

Hi Lisi,

If sharing is turned on and if the person viewing the calendar isn't shared to the sheet, the calendar would be view only.

However, if they are shared to the sheet with at least Editor permission, they'll be able to edit row data from the calendar —except in locked rows or columns.

Changing their sheet sharing permissions to viewer would also prevent them from editing row data.

If you would like to set read only fields from within the Calendar app, I'd suggest submitting a Product Enhancement Request to let our Product team know that you'd like to have this functionality in Smartsheet as it's not currently possible.
