Read Only Objects & Events
Can I make a calendar completely read-only?
Yes. Administrators can configure any given calendar source to be read-only.
Admins can also designate individual users as having read-only access. The read-only option can be set in the calendar settings under the group menu. From there, select the user account you'd like to set and click the yes/no radio button next to Read Only.
Can only some events be read-only?
Only if your original calendar source (like Salesforce or FileMaker) has its own privilege scheme; if it does, DayBack will pick that up. For example, DayBack will respect any access limitations you've crafted in your Salesforce objects. So if you are enforcing that an event is uneditable when it's in a certain state, DayBack will respect that and edits attempted in the calendar will be reverted. This is also true for rules you've set where items can't be seen or edited by certain profiles. Under the hood, DayBack is asking Salesforce to make these edits for you--which is why all your triggers and workflows fire when you edit events in DayBack--and thus a user in DayBack can't do anything with your events they can't do in regular Salesforce.
Yet it would be ideal if DayBack's interface respected your access limitations as well and didn't let users think they could edit events that were otherwise locked.
We're planning to allow you to describe the conditions in which an event would be read-only inside an otherwise editable calendar, but that isn't available yet.
