I hate the EDK. There, I said it. So, admittedly, this is less of a guide to using the EDK, and more of an attempt to convince you to ditch it. ;-) If you're reading this post with any kind of interest, then chances are you've written code with the...

I recently wrestled with this and found it wasn't exactly intuitive, so I wanted to share my findings. What the heck am I talking about? Imagine this scenario. Your MAPI application running on a machine with Exchange 2000 or 2003's MAPI implementation...

I just read Steve Griffin's excellent post on store providers under Outlook 2003 (Read it here .) As luck would have it, I just happened to be investigating an issue with a third-party MAPI provider and Outlook 2003's shortcut bar. The problem reported...

I just recently worked through an issue where messages in a custom message store would not sort on the Subject field. Other text properties sorted fine, just not Subject. The problem was because Outlook doesn't sort the Subject field on PR_SUBJECT...

The title says it all. If you've got a web page hosted on a site that does GZIP compression, you can't point CDO's CreateMHTMLBody at it. You'll get back one of a few different errors, depending on your IE setup. The ones I've seen are (with IE 6.0 SP1...

I was pulled into a neat little issue with a custom message store that didn't behave correctly with appointments in Outlook. It seems that everything was created fine, and Outlook set all of the named properties correctly on appointments. The custom store...

I've been working with MAPI for over 5 years now. In that 5 years I've supported my share of developers writing their own MAPI providers (message store, transport, address book), but I've never actually sat down and written one myself. Until now ;-) ...

Yep, that's right: IExchangeManageStore5 is upon us. And this is the coolest one yet! I'm intrigued...what does it do? The cool new feature in this interface is the ability to retrieve a mailbox table (or public folder table) that contains only...

I get a lot of questions about Outlook's infamous RPC Canceller. I'm sure you've seen this at some point (if you've used Outlook 2002 or 2003 with Exchange server). The RPC Canceller is the feature that gives you that fun little dialog: "Outlook is retrieving...

Just a quick entry to post this sample. A few folks have had trouble getting the Account Management API to work correctly. This is a simple sample I wrote to enumerate the accounts in a profile that hopefully will help. Download it here .

A lot of folks have hit this apparently, so I wanted to share my findings and how to fix it. PROBLEM If a non-admin user logs in to the Sample Control Panel that comes with the HMC 3.5 Consolidated Server Deployment Guide (MPSSampleCP), they cannot...

If you followed our deployment guide to the letter, then chance are your WSS 3.0 setup isn't 100%. There's a big problem with the deployment guide for WSS that can break "multi-tenancy." Here's how you can check if you are broken and how you can fix the...

Patching HMC has never been a fun process. Unlike most Microsoft products, HMC patches don't come in nice neat installer packages that can just be installed on top of your existing setup. This causes some consternation, since we're used to being able...

I'm a Premier Field Engineer with Microsoft Services. I support the Hosted Messaging and Collaboration solution.

Yes, Exchange 2007 SP1 is out . No, it has not been cleared with HMC 4.0 yet. At this point you should not install SP1. We are working on getting this tested and should have an update soon. Until then please be patient! I am pleased to announce that...

I was notified this morning that a recently released security fix for WSS 3.0 has some severe performance issues for folks using host-header mode with a large number of sites (sound like anyone you know?). Read below for the official announcement: ...

Ok, not really, but I am moving to a new role here at Microsoft. I've been doing Messaging developer support for over 5 years now, and it's been great. The team I've worked with over the years is made up of some greatest folks I've ever met, and it was...

By now most people have discovered that installing Windows 2003 SP2 on your Provisioning Engine servers (MPS01 and MPS02 in the reference architecture) breaks provisioning completely . The problem is that SP2 includes some updates to the MSXML parser...

It's been almost 2 years since I joined the Premier Field Engineering team here at Microsoft to support the HMC solution. A lot has changed since that day. We've seen a new version of Exchange roll out, and a new version of HMC to go along with it. Today...

Have you seen any OAB's mysteriously disappear? Then you're going to want to check out this knowledge base article, then call support to get them to send you the hotfix. Users cannot download offline address books in Exchange Server 2003 when you use...
