Daily Digests are a great alternative to receiving numerous calendar item notifications in your email. The digest will send you a summary of all the items you own or follow or assigned to depending on the preferences you set.
You can manage your Daily Digest settings by going to Email Digests under Profile Settings.
Hour to send digest: This is where you can customize the time you’d like to receive the daily digest.
Days to look ahead: This is where you can set up the days ahead. For example, if you have items that are coming up in 3 days, you will be notified of those items are coming up.
Days to look behind: This is where you can set up the behind. For example, if you have items that are overdue from 3 days ago, this is where you will be notified of those items that are overdue.
