When an export is performed on Exchange Server, the E-Mail Addresses
column of the export file is, by default, populated with the
default Exchange Server e-mail addresses in the following order:
MS:MS Mail address
SMTP:SMTP address
X400:X.400 address
CCMAIL:cc:Mail address (only in Exchange Server 5.0)
However, if you manually change one of these e-mail addresses for a
particular mailbox on that server using the Exchange Server Administrator program,
and then perform the directory export, the
e-mail address types may be populated in a
different order in the E-Mail Addesses column for that mailbox. For example, the order may be: CCMAIL, then
MS, then SMTP, and then X.400.
