About Anti-Spam Settings
Microsoft Outlook allows users to specify settings for each account to help protect the account from spam. Such anti-spam settings are stored in a section designated for that account in the user’s profile. Use the PROP_ACCT_PREFERENCES_UID property to obtain the unique ID (UID) for the section in the profile that stores the user’s preferences for this account, including the anti-spam settings.
Use the following properties to obtain anti-spam settings for the account:
PidTagSpamJunkSenders—Specifies a semicolon-delimited list of email addresses and domains that the user has specified as blocked senders for the account.
PidTagSpamThreshold—Specifies the level of spam-filtering that the user has specified for the account. The following table shows the supported values.
