SYMPTOMS
When you browse a mailbox item by using Outlook Mobile Access against a Microsoft Exchange Server 5.5 computer by means of the Mobile Information Server Exchange Server 5.5 Data Provider service (OMA55), you may receive the following error message:

The server rejected one or more recipient addresses.



CAUSE
This problem can occur if the item that you are attempting to open contains backslash characters (\) in the From box, for example:

John Smith \(E-mail\)

This situation can occur if the message is sent by a user who is using either Microsoft Outlook 2000 or Microsoft Outlook 2002 that is running in Internet mode and that is connected to an Exchange 2000 computer by using Post Office Protocol version 3 (POP3) or Internet Message Access Protocol 4 (IMAP4) and Simple Mail Transfer Protocol (SMTP). When Outlook runs in this mode, and the user sends the message in Microsoft Rich Text Format (RTF), and not in the default format, which is Hypertext Markup Language (HTML), to a user on an Exchange Server 5.5 computer, backslash characters occur in the address of the message.



WORKAROUND
To work around this problem, ensure that either the Outlook 2000 or Outlook 2002 client is using the default HTML setting when you are sending messages to users who read them by using OMA55.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
This type of address can occur if either Outlook 2000 or Outlook 2002 is running in Internet mode and connecting to an Exchange 2000 computer by means of POP3 or IMAP4 and SMTP, and the message is sent out in Microsoft RTF. When the mail is sent from either Outlook 2000 or Outlook 2002 to the SMTP Service on the Exchange 2000 computer, the address of the message can have backslashes and a Transport Neutral Encapsulation Format (TNEF) format.

If the particular recipient is set up to send mail in Microsoft RTF, which is not the default format for either Outlook 2000 or Outlook 2002 in Internet mode, to a recipient on an Exchange Server 5.5 computer, the preceding error can be reported when the recipient opens the message with OMA55. When either Outlook 2000 or Outlook 2002 runs in Corporate mode (remote procedure call [RPC] or MAPI), neither of them generate the backslash characters in the address nor do they have the problem with OMA55 (that is described in this article). Also, Outlook 2000 running in Internet Only mode against an Exchange Server 5.5 computer with either POP3 or IMAP4 and SMTP does not generate this type of address.
