<p>Microsoft is working on issuing future update releases for its Forefront Threat Management Gateway (TMG) and Unified Access Gateway (UAG) products, mostly to help with publishing Exchange 2013.</p><p>Currently, it's not practical to use UAG to publish Exchange 2013, according to this Exchange team blog post by Greg Taylor, a principal program manager for the Exchange customer experience. Doing so requires that some of UAG's security features be disabled, he noted. The issue is tied to Microsoft's Outlook Web Apps (OWAs), which were rewritten to work with Exchange 2013, causing confusion for UAG. Taylor advises UAG users to just wait for the forthcoming update, which will add support for Exchange 2013.</p><p>It's not clear when those UAG and TMG updates will be available. While Microsoft is planning a "general availability" release of Exchange 2013 in the first quarter of next year, the product has been available earlier this month to Microsoft's volume licensing customers, as well as its TechNet and MSDN subscribers. So those early adopters may be all ready to go with Exchange 2013, but they'll face a bit of a snag with enabling remote e-mail access.</p><p>Exchange 2013 presently lacks its own publishing wizard and UAG can't be used. TMG can be used to publish Exchange 2013, but it involves making a few new settings changes compared with publishing Exchange 2010. The details on how to configure TMG to publish Exchange 2013 are described by Taylor in the blog post. For instance, the logoff parameter has changed and the delegation priorities for Outlook Web App authentication need to be modified.</p><p><a href="http://redmondmag.com/articles/2012/11/26/microsoft-planning-tmg-and-uag-updates.aspx">Keep reading...</a></p>
