Most address book providers support at least one container, some of them modifiable. Address book containers can supply contents and hierarchy tables, search capabilities, and name resolution. Modifiable containers allow the deletion of entries such as messaging users, distribution lists, or other containers and the addition of entries from entries in other containers or from one-off templates.
The following table describes features that are required of address book providers that have containers, modifiable or read-only, and how you implement them.

| Access messaging users | Implement the IABLogon::OpenEntry method. See Opening Address Book Entries. |
| Compare messaging users | Implement the IABLogon::CompareEntryIDs method. See Comparing Address Book Entries. |
