HTTP_500 and Activesync
When synchronizing your mobile device with Exchange 2003 you may see the following error:
Error code: HTTP_500 Synchronization failed due to an error on the server. Try again.
There is a good KB that covers this issue; KB886346 - "You receive an HTTP_500 error message when you synchronize your mobile device with Microsoft Exchange Server 2003". This article deals primarily with SMTP address mismatch. But I have noticed especially with SBS there are a couple of other factors that come into play that can trigger this error.
- URLScan ISAPI filter - if you are using URLScan it places an ISAPI filter in the ISAPI filters tab in the properties of Web folder in IIS. - Remove it.
- Location: Open IIS - expand the server icon - select properties of the Web Site folder - ISAPI filters tab.
- Permissions are incorrect on the exchange-oma website
- Location: Open IIS - expand the server icon - Expand the Web Sites folder - select the properties of the exchange-oma website - Select the Directory Security tab - select the edit button under Authentication and access control
- The correct permissions should be:
- Integrated windows authentication - checked.
- Basic authentication - checked.
- All other check boxes should NOT be selected.
- Permissions are incorrect on the microsoft-server-activesync website
- Location: Open IIS - expand the server icon - Expand the Web Sites folder - select the properties of the microsoft-server-activesync website - Select the Directory Security tab - select the edit button under Authentication and access control
- The correct permissions should be:
- Basic authentication - checked.
- All other check boxes should NOT be selected.
