Sync Conflict: Method Not Allowed

In some environments you may receive an error after updating a record. The error is presented as a Sync Conflict with a detail that says "Method No Allowed".

This is generally an issue with the web server configuration. Confirm that WebDAV is installed on the server. This is found under the role installation in Server Manager. WebDAV publishing is located here: Web Server (IIS) > Web Server > Common HTTP Features > WebDAV Publishing. If WebDAV is installed, confirm that the following section is uncommented in the web.config file associated with the IDORequestService located on the utility/web server:

<!-- 3May18 - jcurry - If WebDAV is installed on a server these lines should be uncommented.  Needed to allow REST service to use PUT verb.

      <modules>

         <remove name="WebDAVModule" />

      </modules>

      <handlers>

         <remove name="WebDAV" />

      </handlers>
