    text
    copied!<p>I've recently coded a .NET Console app using C#. It's purpose was to read the emails within a specific folder, parse them for specific values and save them to a database.</p> <p>Our email system, at the time I originally coded this, was Exchange 2003. However, I was made aware we would soon be upgrading to Exchange 2010: ergo, I built the code to work in both environments. </p> <p>Following the migration to Exchange 2010, however, the app has broken. </p> <p>The app uses the EWS API for 2010 functionality. When it attempts to use the ExchangeService's FindFolders method to find the publicfoldersroot, it throws an exception. Here's the code:</p> <pre><code>ExchangeService service = new ExchangeService(); FindFoldersResults findRootFldrs; service.UseDefaultCredentials = true; service.AutodiscoverUrl("xxxxx@xxxx.xxx", delegate(string x) { return true; }); FolderView fview = new FolderView(100); fview.Traversal = FolderTraversal.Deep; findRootFldrs = service.FindFolders(WellKnownFolderName.PublicFoldersRoot, fview); </code></pre> <p>The exception: <code>ErrorInvalidSchemaVersionForMailboxVersion</code>, aka:</p> <blockquote> <p>The mailbox that was requested doesn't support the specified RequestServerVersion</p> </blockquote> <p>I've attempted:</p> <ul> <li><p>Setting the exchangeservice to 2007 (throws an exception: "An internal server error occurred. The operation failed.")</p></li> <li><p>Giving myself the highest level of permission to the Public Folder (no effect)</p></li> <li><p>Manually setting my credentials (no effect)</p></li> </ul> <p>I can view the public folders in Outlook 2007; the publicfoldersroot property is available in the intellisense; the code works on local folders (I can parse my inbox).</p> <p>My current thinking is that it's a setting on the recent setup of Exchange 2010: unfortunately that isn't really my field. The exception tells me it's trying to use a previous version of Exchange. Setting it to 2007 simply causes the code to fail with an internal server error. </p>
