Types of Contacts
Personal Contacts
By default, all the contacts you add are Personal Contacts. You can view, modify or export them from your account. All your personal contacts will automatically appear in your address book. You can add categories to Personal contacts, group them and use them to add multiple contacts during Compose.
Organization Contacts
When the organization administrator adds a user or group, the email address is automatically added to the Organization's contacts. All the organization contacts appear automatically in the autofill when you compose emails. When a new user is added to the organization, the user can easily look up or compose emails to colleagues using the Organization's contacts.
The Organization's contacts are common for all the users of the organization. All members can view the contacts and use them. However, only the organization administrators can add, edit or delete the contacts from the organization contacts.
Apart from the internal organization users, if you want to add any common external contact, for users to access easily, the organization administrators can add them. This will be useful for third-party contacts common to the organization or other service providers of the organization.
The organization contacts you have added will be used in multiple places like Search, Tasks, Folder Sharing etc.
Contact Categories
You can group a fixed set of contacts by adding them into a category. The Categories help you to add a 'batch' of bulk contacts to your email when you compose an email. Personal and Organization Categories are listed in the 'Address book' for easy access while composing an email.
Creating Categories
You can create a new Category by clicking on the Add Category option on the left pane in the contacts section. You can also create contact categories directly from the Address book in the Compose editor. Click here for detailed instructions.
Note:
Categories can be added to the Organization or Group only by the Delegated/ Department administrator of your organization or group.
Adding Contacts
You can add contacts to categories by dragging and dropping the contacts into the desired category. You can add multiple contacts at once to a category by selecting the relevant contacts and clicking on the Add to icon.
If you want to remove a contact from its category, click on the relevant contact in the category list and select the Clear contact icon.
More Options
You can right-click on the Category to Rename or Delete them. You can use the Export option in the right click to export only the contacts in that category.
