Importing users with multiple email addresses

The correct syntax for multiple proxyAddresses

The correct way to format the proxyAddresses value when you have multiple addresses is to separate each address with a semi-colon, the address can be enclosed in quotation marks if necessary but this is not essential.

”SMTP:user@domain.com;smtp:user2@hotmail.com”

Notes:

  1. The uppercase SMTP denotes the primary address.
  2. A lowercase smtp denotes the secondary addresses.
  3. There is no way to guarantee the order that the addresses are displayed when viewed in AD Users & Computers.
