Renaming a UPN to another federated domain
During an ongoing Office 365 deployment, we identified an issue with Office 365 customers not being able to change a user’s UPN if both UPN’s are in federated domains. We have identified and validated a work-around, please see the guidance below. Thanks to Dmitry Kazantsev for help in the write-up, this...

Exchange 2010 puts TargetAddress in ProxyAddresses?!
MMT is the BPOS-D migration tool and it uses Exchange 2010’s built in move service called MRS (Mailbox Replication Service). MMT, through MRS, analyzes the mailbox, enforces any customer migration rules (such as ignore calendar items older than 2 months), moves the contents of the mailbox, validates...

Microsoft Online and SBS 2003
I have been working with the Microsoft BPOS aka Microsoft Online guys in Enterprise accounts for a while to help big companies migrate to BPOS dedicated. Don’t know what that is? Check out www.microsoftonline.com . To sum it up, it is hosted Exchange, SharePoint, OCS, LiveMeeting, and a few other offerings...

My iPhone 3G Review
Call me a traitor. Call me weak minded to the Apple Jedi mind trick. Yes I have a 3g iPhone, the cheapest one of course. My Treo 750, which I really liked , was starting to have some battery fade. In addition, I was using the IE browser on my Treo more frequently, with more and more contempt for IE...

Exchange 2007 – Snags during my upgrade
This week I had some time to spend in my lab at home, so I thought I would catch up on some overdue projects, My biggest project was to get my lab up to Exchange 2007 from 2003. The complication here is that although I have a rack of “real” servers, I don’t have any spare capacity. Virtual PC to the...

Seriously scary Blackberry
For years, competitors to Blackberry have been pointing out the inherent security flaws with RIM’s services such as, um, all your corporate data flows through their network (along with all your competitor’s data). Microsoft's play around this is the fact that Exchange Active Sync doesn’t flow over someone...

Exchange 12 Stuff that I liked
I got a sneak preview of the Exchange 12 at TechReady and got excited about a few things. Since most of the features are included in beta’s I can share them with you. 1) New server roles. Gone is the idea of a “Front End Server”, instead there will be several roles that a server can have. This eliminates...

Bedlam DL3 (revisited)
So, I am on a few distribution lists that pertain directly to my every day job. I have a few others that are nice to look at because there is interesting stuff. One of the hobby DL’s that I like to read is our “Pocket PC Users and Enthusiasts”, which we share all kinds of gripes and praise about our...

Gripes and praise about Communicator Web Access
I am working on an LCS design for a customer and saw that LCS’ Communicator Web Access shipped in December. I read the docs and discovered that it works a lot like Outlook Web Access (OWA) because it uses forms based authentication. I was surprised at this because I assumed that we would have created...

HVMC v3.5 training
I am up in Redmond this week for training on our new High Volume Messaging and Collaboration (HVMC) release, v3.5. I got "nominated" to go to the training because both Gloria Alexander and Todd Luttinen, our resident Hosted Exchange experts, deserted us and moved to product teams (Todd went to Exchange...

Small Business Server 2003 Upgrade from Hell
Last week, I decided to take a few vacation days and fly out to Ogden, Utah to help my wife’s old company upgrade from Small Business Server (SBS) 2000 to SBS 2003. They are a small, 10 person operation that manufactures high end ski and board apparel ( www.descente.net or www.ridedna.com ). The have...

Microsoft Support from India
I admit it, I am not the all-knowing Microsoft consultant I should be. The real truth is, our support folks have the best tools to diagnose problems a lot faster than I can muddle through things. I have had the occasion over the last few weeks to call Microsoft Support (PSS) several times with...

Turn off MAPI on Exchange, good news for hosters, but....
I just saw this post from the Exchange team . This is great news for hosters that want to offer a choice of packages, but does it really save anything? OWA is as big of a pig as a full MAPI user, just without the hassle of client configuration. Support teams win, but the infrastructure doesn’t gain anything...

RANT: Exchange Calendar and Contact email problems
I don't know exactly what or when this happened, but email has become a lot harder to use, especially around sending appointments or contacts. Most of my customers have Exchange 2003, Microsoft has Exchange 2003 and I have Exchange 2003 here at my lab at home (where I host several SMTP domains). Most...

Microsoft to Acquire FrontBridge Technologies, a Leading Provider of Secure Messaging Services
Cool news for Exchange! But, won't this be seen as competing with our partners that are ASP's? Hosted Exchange, bah, we will do it ourselves...

iSCSI, cheap disk for archiving?
Back in 2002, I was involved in migrating some of Microsoft’s biggest ISP customers from a product we called MCIS (Microsoft Commercial Internet Server) to Exchange 2000. I was the project manager for Deutsche Telekom (DT) were we had several hundred thousand email boxes and about 40,000 SMTP domains...

SAN, SAN and SAN
I can't believe how important storage has become. I am working on some Hosted Exchange projects, and disk makes or breaks the environment. Dave Lalor from our internal IT group wrote an awesome paper with HP about their EVA storage. Unfortunately, it doesn’t apply to EMC or Hitachi . Matt Gossage also...
