DOCUMENT:Q294406 11-JUN-2002 [exchange] TITLE :XIMS: IMAP Cannot Open Appointment Items by Using SSL PRODUCT :Microsoft Exchange PROD/VER::5.5 OPER/SYS: KEYWORDS:kbFEA kbExchange550SP5Fea ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: Q256986 Description of the Microsoft Windows Registry SUMMARY ======= When an Outlook user sends a meeting request to a user who uses a Post Office Protocol version 3 (POP3) or Internet Message Access Protocol (IMAP) client, that user may not be able to open the meeting request in the POP3 or IMAP client. The Uniform Resource Locator (URL) for the meeting request may not work. This behavior occurs if Microsoft Outlook Web Access (OWA) is configured to use only Secure Sockets Layer (SSL); the meeting request URL that is generated for the POP3 or IMAP clients is stamped with "http:" rather than "https:". MORE INFORMATION ================ A supported feature that modifies the product's default behavior is now available from Microsoft, but it is only intended to modify the behavior described in this article and should be applied only to systems having a specific need for it. This feature may receive additional testing at a later time, to further ensure product quality. Therefore, if you are not severely affected by the lack of this feature, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack that contains this feature. To obtain this feature immediately, contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web: http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS The English version of this feature should have the following file attributes or later: Component: Information Store +-------------------------+ | File name | Version | +-------------------------+ | Store.exe | 5.5.2654.81 | +-------------------------+ NOTE: Because of file dependencies, this feature requires Microsoft Exchange Server version 5.5 Service Pack 4. After you apply this Store.exe feature fix, if OWA is configured to use SSL only, you need to edit the registry on the Exchange Server computer. WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. If OWA is configured to use SSL only, perform the following steps on the Exchange Server computer: 1. Start Registry Editor (Regedt32.exe). 2. Locate and click the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersPrivate 3. On the Edit menu, click Add Value, and then add the following registry value: Value name: OWA Url Protocol Data type: Reg_SZ Value data: https: 4. Quit Registry Editor. NOTE: Data must end with a colon (:).
