Now that Exchange Server 2013 is available, some of you may well be wondering how to publish it to the Internet using Microsoft Threat Management Gateway (TMG) or perhaps the Microsoft Unified Access Gateway (UAG). This post will help you configure TMG, for sure, but not UAG – as for the time being, you can’t effectively publish Exchange Server 2013 using UAG without turning off many of the security features in UAG. Why’s that? Well, as you’ll have gathered from other posts on...

Have you ever gotten a call from someone you know whose Outlook client is having trouble connecting to their email server? Don’t you just wish you had a tool that you could send to them that would walk them through a connectivity test and provide a simple way for them to send the results back to you? Or perhaps you’re an administrator that has been using the Remote Connectivity Analyzer for years to verify email configuration, but wish you had a way to verify the same tests from...

Recently, we have released a Guided Walk Through (GWT) for troubleshooting public Folder replication issues in Microsoft Exchange 2003.  There are a couple of ways to access the troubleshooter.  You can use the link here to access it directly.  As well, it will be embedded in various related public folder replication articles such as the following:  http://support.microsoft.com/KB/842273 . Now, I know you are wondering why we came out with a troubleshooter...

We’ve heard your concerns and take them seriously. We’re looking into what we can do to improve this situation for you, nothing definitive yet but be assured we’re working on it and will post an update asap. Quick note to inform you that we've updated Exchange TechNet Library.

Modern public folders – ready for Office 365 We made significant architectural changes with modern public folders to deliver against the feedback we got from customers: “Having a separate management and replication model is complicated and expensive.” “We don’t get public folders in Office 365 so we cannot migrate to the service.” “We want public folders, don’t take them away!” Built on mailbox infrastructure Building on known mailbox infrastructure greatly simplifies management...

One of the biggest benefits that Exchange Server 2013 provides is that it enables personal information sharing among different people in different organizations. Email itself is a great example of sharing because it allows people to easily share thoughts, images, and attachments. However, using federated sharing in Exchange 2013, you can share much more than just email. Federated sharing allows your users to share calendar free/busy information and additional calendar/contact...

OAB History Offline Address Books, fondly referred to as OAB s, are a critical component in Exchange infrastructure for a long time now. An OAB is used by Microsoft Outlook clients in Cached Exchange Mode for address book lookups when offline. OABs are also critical in reducing the workload on Exchange servers as cached mode Outlook clients will always query the local OAB first. The OAB has evolved over Exchange releases. The last major overhaul of OAB architecture was in...

One of the great benefits to running one of the world’s largest Exchange deployments is that we at Microsoft get to see all the things that our customers face on a daily basis. With the recent release of iOS6, we have noticed a marked increase in support calls due to meetings having the owner of the meeting changed (sometimes called “meeting hijacking”). Most instances reported to us to date involve users with delegates who first open a meeting request in Outlook and then act...

Exchange 2010 includes a feature called Datacenter Activation Coordination (DAC) mode that is designed to prevent split brain at the database level during switchback procedures that are being performed after a datacenter switchover has occurred. One of the side benefits of enabling DAC mode is that it enables you to use the built-in recovery cmdlets to perform the datacenter switchover and switchback. In the real world, there are several different factors that determine what commands...
