Address Book
This section describes the design decisions associated with Exchange Online for system(s) built using ASD's Blueprint for Secure Cloud.
Estimated reading time: 1 minute
The Outlook Address Lists, Global Address List (GAL), and Offline Address Book (OAB) are collections of mail-enabled objects. They are leveraged for recipient lookup operations (i.e. When a user leverages either the Address book or Check names tools in Outlook). The types of mail-enabled object collections are as follows:
- GAL – The GAL is automatically created by Exchange and lists all mail-enabled objects. (The GAL is available by default to all users).
- OAB – The OAB is an offline version of the GAL leveraged by clients in Cached Mode.
- Outlook Address List - An Outlook Address List is a subset of the mail-enabled objects. By default, a number of Address Lists are created, however, additional Address Lists can be created as required.
Design Decisions
| Decision Point | Design Decision | Justification |
|---|---|---|
| Custom Address Lists | Configured | Custom address lists can be configured by organisation administrators, however one initial custom list, OrganisationName-All, should be manually created. |
| GAL and OAB | Generated | These will be generated so that users can send emails within the organisation in accordance with Microsoft best practice. |
