Centralizing Corporate Contacts

We need all employees to be able to seek out contacts from one Contact Database. Is this possible?

When an employee updates and / or loads a new contact, this should be visible to everyone. Don't know how to do.

How to merge everyone's contacts from MS Exchange and also from each other? Need to understand best methodology.

Daily Agenda to Email

Get your daily agenda in your inbox

In Calendar, go to Settings settings > Settings.
On the left under Settings for my calendars, click your name and go to General notifications.
In the Daily Agenda field, click the Down arrow arrow_drop_down next to None and select Email.

Start your day with a daily agenda in your Gmail inbox, based on your Google Calendar schedule.

You can even give your daily agenda to your team or an assistant so they know the best times to reach you.
