This article was previously published under Q173544

SYMPTOMS

When you try to send security keys to a user in another organization, instead of getting the Security Key Exchange Message dialog box, the user gets the following message: 
   You have received Public Security Keys from another user. Your version
   of Microsoft Exchange client does not support this feature. You may
   need to upgrade to a newer version in order to use these keys.

CAUSE

This is caused by not sending the security keys with Rich Text Format. When Rich Text Format is not used, the Internet Mail Service strips out the form used for sending security keys.

RESOLUTION

To resolve this problem, perform one of the following two procedures:

  • In the Exchange Administrator program:
    1. Go to Properties of the Internet Mail Service.
    2. Select the Internal Mail tab.
    3. Under Message Content Information, choose Interoperability.
    4. In the Send Microsoft Exchange Rich Text Formatting box, select Always.
    -or-
  • In the Exchange client:

    1. Choose Tools, Address Book.
    2. Go to File, New Entry, and select Internet Address.
    3. Select the check box for Always Send to This Recipient in Microsoft Exchange Rich-text Format.
