Migrating to Exchange

Choosing the Addressing Conventions

You can use three different types of addresses in the Sender, Display-Name, or E-mail-Address fields of .pri files.

Display Name

The display name is the friendly name of a recipient. Source extractors should convert message recipients, senders, and appointment attendees to display names. Outlook compares the display name with personal and global address book entries. If it cannot find a match, it displays possible matches for the user to choose from.

E-mail Address

Source extractors use unique identifiers to relate each mailbox or contact in the existing system to each mailbox or contact in Microsoft Exchange 2000 Server. These identifiers are known as source e-mail addresses and are stored in the following format:




This address is created in the directory section of the primary file and must be in a column with a header of Secondary-Proxy-Addresses. You can remove the imported secondary proxy addresses after migration is complete, providing you will not be using a connector to connect Exchange users to your old system.

E-mail addresses are also used for the Personal Address Book (PAB) entries. By default, the following address types are valid: MS, MSA, X400, and SMTP. Other gateway address types can be made available. Exchange defines an address for a foreign system recipient in this format:




When extracting addresses from foreign systems, your source extractor must create a target address, or extract the address as a direct address.

Also consider these PAB addressing issues:

Display Name with E-mail Address

The source extractor can use display names with e-mail addresses. Use this format only for addresses not in the Exchange global address list (GAL).
