Hello all, 1) Does the MAPI property PR_EMAIL_ADDRESS - allow special char like (,),[,],/ etc ?2) Is this property a unique name in the Active Directory ? Thanks, atvelu

Hi atvelu, 1.PR_EMAIL_ADDRESS is used in conjunction with the PR_ADDRTYPE and PR_MESSAGE_CLASS properties in addressing messages. The string format is qualified by PR_ADDRTYPE. The string provided by PR_ADDRTYPE can contain only the uppercase alphabetic characters from A through Z and the numbers from 0 through 9.For example SMTP, then the format of Internet e-mail addresses is defined in RFC 822, special char like (,),[,],/ cannot be included in the SMTP EMAIL ADDRESS. The valid PR_ADDRTYPE can be found in the below article. Messaging System Address Types http://msdn.microsoft.com/en-us/library/ms527059(EXCHG.10).aspx RFC 822: Notational Conventions http://msdn.microsoft.com/en-us/library/ms527309(EXCHG.10).aspx Exchange Server RFC and standards compliance http://support.microsoft.com/kb/262986 2. It should be unique in AD. Hope it helps.
