Before you deploy password encryption for your Entourage 2008 users who have POP or IMAP accounts, you must know whether the POP server or IMAP server accepts password encryption. If the server does not accept password encryption and users configure their accounts to use this type of encryption, they might not be able to receive their incoming messages.
Enable password encryption for POP and IMAP accounts in Entourage 2008
On the Tools menu, click Accounts.
On the Mail tab, double-click the IMAP account or the POP account.
On the Account Settings tab, click Click here for advanced receiving options, and then select the Always use secure password check box.
