  • Managing Access to the Exchange Online Service

    In this installment we talk a little bit about how we have built on the underlying RBAC infrastructure and PowerShell to enable zero elevated access in the service. This is a very important part of the overall access control system that makes sure that...
  • Multi-Release Strategies and Role Based Access Control

    Following the ‘why we built Exchange the way we did’ theme, I wanted to take some time to explain some architectural changes that have been made to Exchange over successive releases. After Exchange 2003 shipped we took a step back and assessed...
  • Moving Mailboxes with the Mailbox Replication Service

    Welcome back to lovely sunny Seattle/Redmond, figuratively speaking of course. This video is a discussion about our approach to moving mailboxes—the Mailbox Replication Service (MRS). Starting with Exchange 2007 SP2 moving forward, administrators...
  • Immutability in Exchange

    In this video we spend some time talking about an aspect of our archiving and compliance story for Exchange on-premises and the service. Specifically, if you do decide to take advantage of the simplicity and lower costs of co-locating your ‘archive’...
  • Archiving Questions: Do Tiered Storage and Stubbing make sense?

    This blog business has been turning out to be more fun than I expected - maybe I should be nicer and less sarcastic when the marketing team suggests these ideas. This time, answering the questions from my archiving blog and video have led into some...
  • Running a Secure Service

    The Ask Perry blog is alive! In this edition I spend time discussing a topic I frequently hear from customers, "how do we run a secure Office 365 service". I am joined by my new host Julia White to review this topic both from a data center view...
  • New Exchange Architecture

    Well the new version of Exchange is almost ready to be released and the first MEC in a decade is starting in a few days!  So we can actually start talking about what is in the next version of Exchange for our on-premise customers and for our the...
  • Smart Indexing in the New Exchange

    One of the big shifts that continues to reshape the software industry is the rapid drop in the cost of storage. These costs are dropping so rapidly that in addition to the absolute costs dropping rapidly there is also a rapid shift in the relative cost...
  • Shifting to a Services Culture

    In my last Geek Out video we talked about the interesting technical differences in building a service versus building software for companies to run on-premises. This time we spend some time talking about the cultural shift the team went through as services...
  • New Scalable Exchange Server 2010 Solution from HP

    It is pretty exciting to see HP release a new hardware solution that provides a simple scalable solution to build the smallest and largest Exchange deployments. This new solution maps closely to the architectural building block concept that I’ve...
  • Special Edition Geek Out with Perry – TechEd Europe 2010

  • High Availability for the Exchange Service

    It has been a while since my last posting. We have been pretty busy dotting the i's on the new Office 365 service, and deploying the beta (which has gone very smoothly). The conversation this time is centered on the framework through which we have...
  • Why Migrations Instead of In-Place Upgrades?

    After a brief break from blogging, I was back in the studio recently recording more videos to answer questions about Exchange design decisions. Now most of the time I talk to customers about new functionality that we have added to Exchange, and for the...
  • Responding to Migration vs In-place Upgrade comments

    There were some interesting comments from the last video entry, and they distilled into a few interesting themes that I wanted to respond to: 1) Perry, you seem to be living on a different planet than I do—one where spindles don’t last...
  • Exchange Archiving

    So far we have spent some time talking about how Exchange has been engineered to take advantage of large commodity storage while keeping the data protected and the overall system highly available in order to deliver large, low cost mailboxes. This...
  • Exchange Data Protection

    Well, dealing with the creative responses of my co-workers after the first video was so much fun -- comments like "The man may excel at computational data storage and analysis, but he needs to learn a thing or two about whiteboard real estate" So, why...
  • Getting the conversation started

    Well, I guess I really am joining the blogging bandwagon. Although, I suppose blogging has been sufficiently eclipsed by Twitter that it can't really be thought of as a bandwagon anymore. At least not a cool bandwagon. The preceeding is by way of a welcome...
  • Running a Service with Large, Low Cost Mailboxes

    This video provides some answers to the question we’ve heard a lot – How can you provide large mailboxes in the service at such a low cost? In the video, I talk about some of the ways that enable us to get the costs of our service so low,...
  • Archiving and Large Mailboxes

    The last blog post generated some great questions, and I wanted to address some of them in a little more depth and continue the archiving discussion. “We are all for removing pst files from the network; however, the major challenge that we have...

    So far there have been some great comments and questions in response to the first couple of blogs. In the last written entry I responded to one of the comments. In the new video I recorded with Ann Vu, she gives voice to a few of the other great questions...
  • Exchange Mailbox Storage Bricks

    This time I wanted to respond to one of the comments from my last blog post " ... apart complementing Perry for a great presentation .. a common mistake done by many companies is mixing two concepts, such as Data Protection and Service Continuity... ...
  • Storage performance and my take on virtual storage

    There were some good questions raised from my first blog post which I'll answer here. First, yes Exchange 2010 should seem a little snappier on the similar hardware compared to Exchange 2007 and especially compared to 2003. But the snappiness should...
