Last fall, the Outlook documentation team approached me about using an Outlook Social Connector provider I built for an internal social network we have here at Microsoft (called OfficeTalk) as an example for a Visual How-To series on MSDN. It took a few months to get it all done, but you can check out...

You may have heard of OfficeTalk . You may have heard of the Outlook Social Connector . As it turns out, my team is responsible for supporting developers building Outlook Social Connector (OSC) providers for their social networks. As a means of learning about how the technology works in preparing myself...

We had an issue recently where the customer had written an application to process MIME messages that had body parts encoded with the koi8-r charset …or at least that’s what it said: ------_=_NextPart_001_01C9F067.D9742103 Content-Type: text/plain; charset="koi8-r" Content-Transfer-Encoding...

I recently had a case where a customer was asking how to figure out the mailbox version of a given user using Exchange Web Services (EWS). We noticed there is a node returned in the AutoDiscover response message called ServerVersion, but this value seems pretty opaque. Here’s a snippet from the AutoDiscover...

Matt , Rick , and I were working on an issue recently where when an application using EWS would set a contact’s Street address to a value containing a carriage return and line feed, like this: physicalAddress.Street = "1234 56 Ave NE\r\nc/oPatrick Creehan" ; the address card control...

Misha, a Senior Dev on the VSTO team just posted this blog describing why handling events in managed code can be problematic. This is not news to our team, but he provides a good explanation of why it’s problematic. Misha Shneerson : COM Interop: Handling events has side effects If any of what he says...

We get calls about this all the time. You have a CDOSYS application that…what? No, I’m not talking about automobiles, why did you…oh, the title. Well, it’s true. Read on. The Dreaded Transport Error The problem we see more than any other is when a customer is trying to send a lot of e-mail using...

I had a case on this a few months ago, but thought more folks might run into this as they start moving to form regions. By default, if you use the VSTO template for creating a form region in Outlook, the item is leaked. This can show up in a number of different symptoms, but the one we saw was that when...

Many of you have been using the Custom Calendar Provider samples created by Stephen Toub and I: Stephen Toub - Custom Calendar Providers for Outlook 2003 Custom Calendar Providers for Outlook 2007 The development team has finally documented pretty much everything you need to know in order to build your...

One of the major requirements most developers are up against these days is ensuring their code runs as fast as possible. No one likes to wait for an application to run, they want seamless, invisible, instant speed. Multithreading is becoming more popular now that many desktops and certainly most servers...

I've been encouraging him to blog his "Matt Stehle's Tenents of OOM Programming" for a while now, and he's finally begun with a series on some common pitfalls we see with developers using OOM in .NET. This first article is concerned with a common reason we see for events to stop firing in your VSTO add...

Many people ask about how to do this, so I thought I'd write up a sample. This sample basically searches the inbox of a user and then does an HTTP GET against the DAV:href to get the EML file and then does an HTTP PUT to upload it to a SharePoint document library. using System; using System.Web; using...

So if you were using Stephen Toub's Custom Calendar Provider sample for Outlook 2003, and you are testing out the awesome new Outlook 2007 features, you may have noticed that the code sample he provided doesn't work any more. Stephen is planning to update the article for 2007 eventually, but until then...
