    How many ways can Outlook archive an item? 2

    In January, I spoke with Javier Soltero, the new General Manager of the Outlook development group, about his plans, hopes, and aspirations for revitalizing the Outlook client family, including Outlook desktop....More

    In praise of the humble archive mailbox 3

    A recent Microsoft blog lauded the wonders of online archives, specifically of the type made available in on-premises Exchange and Exchange Online (just in case you thought otherwise). Interestingly, the post says that “studies suggest that three-fourths of an organization’s intellectual property is contained within email and messaging systems.” ...More

    How Microsoft’s focus on low-cost storage impacts the Exchange market 1

    Following my post on “The story of Exchange IOPS” outlining the journey of Exchange from being an I/O hog to something far less demanding on storage systems, a recent request from Josh Odgers from Nutanix to consider his post “Peak performance vs Real World – Exchange on Nutanix Acropolis Hypervisor (AHV)” seemed to be opportune....More

    The story of Exchange IOPS: How a crusade to make Exchange less of a storage hog enabled a successful cloud service 1

    The history of software is littered with examples of grand strategic changes that never amounted to much when implemented. The crusade to reduce the number of disk I/O operations generated per user per second (IOPS) is an example of how a big bet paid off....More

    How Exchange's Recover Deleted Items option could be improved 5

    Since the introduction of the first "dumpster" in Exchange 2000, users have been able to recover deleted items without asking an administrator to recover the data from a backup. Given the propensity of humans to make mistakes (like deleting an important message in error), the feature has proved to be invaluable over the last 15 years....More

    Exchange says no to .NET Framework 4.6.1 1

    The disclosure on the EHLO blog that Exchange on-premises servers will run into some known issues if .NET Framework 4.6.1 is installed might surprise some, especially because it has become a recommended update distributed by Windows Update, but it’s not really much of a shock....More

    No advanced training available, so what should experienced Exchange administrators do? 5

    A recent message from a reader piqued my interest because it describes a problem that I think many people face today. Here’s what it said:...More

    Online protection the only way to go 4

    Microsoft’s January 14 post “Leading the way in the fight against dangerous email threats” to the Office blog recalled the discussion that ensued in September 2012 after they announced the cancelation of their on-premises email protection products, including the Threat Management Gateway (TMG) and Forefront Protection for Exchange (FPE)....More

    The woes of Exchange mailbox auditing 1

    Mailbox auditing seems like a pretty good thing to have in an email product, if only to answer the eternal question of who deleted a particular message from the mailbox. Exchange 2010 was the first version of the product to include mailbox auditing. The sad news is that not much has changed since in either the cloud or on-premises product, which is both worrying and not particularly good when considered in the context of Microsoft’s overall compliance strategy....More

    Predicting the world of Exchange in 2016 7

    Last week I looked back on what happened in the world of on-premises and cloud Exchange during 2015. This week it’s time to consider what might come along in 2016. Of course, I don’t work for Microsoft, so anything outlined here is total speculation, all done in the best possible taste....More

    Looking back at the world of Exchange in 2015 8

    Probably not such a good idea to disable Managed Availability

    Two previous posts describe why a self-monitoring and healing capability is useful in software applications and provide an overview of how the Managed Availability framework provides these capabilities in Exchange 2013....More

    Active Directory and Exchange - too tight for a rename 3

    1999 seems such a long time ago now, but that's when many of us first faced the need to deploy Active Directory (AD). For many companies, the need arose because Microsoft replaced the Exchange Directory Store (DS), used for Exchange 4.0 to 5.5, with Active Directory in Exchange 2000. The DS was very much like AD....More

    Why mailbox anchoring matters 1

    Tuesday’s EHLO post by Rob Whaley, a well-known Exchange guy who works on beta releases of the on-premises and cloud products, is all about how a remote PowerShell session connects to a mailbox on an Exchange server. Or, to use the term now popularized by the post, “mailbox anchoring”. I confess ignorance on the point as I was heretofore unaware of such a nautical reference in the context of Exchange....More

    Two years on: revisiting a conversation with Exchange development chief Perry Clarke

    Two years ago, I spoke with Perry Clarke, the development chief for Exchange (both on-premises and cloud) to discuss the current state of Exchange and how its technology was likely to evolve. We know how the influence of the cloud has affected the way that product development occurs and how quickly things now happen. I thought it would be interesting to look back on how Exchange has evolved in the period....More

    Building efficient keyword queries for eDiscovery searches in Exchange and SharePoint

    The ability to run searches across a mixture of Exchange mailboxes and SharePoint sites to uncover the deep and dark secrets of those who would prefer their work to go unnoticed is what, in some degree, eDiscovery is all about. Microsoft has invested heavily in the area of compliance over the last decade, with the initial work showing up in Exchange 2010 and SharePoint 2010. There was much to like in the first implementation, especially in Exchange 2010, if only because so many legal discovery actions center on email....More

    Why Microsoft decided to keep deleted items in Exchange Online and why it might be the right decision 2

    Some interesting discussion has flowed into my mailbox since Microsoft announced their decision to stop cleaning out the Deleted Items folder of user mailboxes in Office 365. The announcement appeared on February 20 and started a 28-day countdown to implementation....More

    FUD continues over OWA backdoor exploit 5

    Last week, I wrote about a report issued by security company Cybereason that reported how an attacker had gathered 11,000 sets of user credentials after planting a compromised OWAAUTH.DLL file on an Exchange server. A spirited debate duly resulted and Cybereason commented back on the original post....More

    Doubtful security report about OWA flaw gains headlines but offers little real value 13

    The recent Cybereason report titled “A new persistent attack methodology targeting Microsoft Outlook Web Application (OWA)” probably caused some heart flutters for Exchange administrators who might have imagined that the client had been compromised in some fundamental way. I didn’t have quite that reaction because I don’t think the results described in the report are valid....More

    Exchange 2016 debuts to delight on-premises customers 6

    After what seems to have been a much calmer Technology Adoption Program (beta tests), Exchange 2016 passed all the required quality benchmarks to reach Release-to-Manufacturing (RTM) status on September 29. Of course, RTM is an archaic term dating back to the time when software was ceremoniously handed over by development to the folks who created copies of the distribution kit on floppy disks, then CDs, and latterly DVDs for delivery to customers....More

    All the Exchange news from IT/DEV Connections 2015

    I’m on the way back home after the 2015 IT/DEV Connections conference, which took place this week in the Aria Hotel in Las Vegas. Thankfully, everything seemed to run smoothly and the Enterprise Collaboration track functioned without too many problems. We had to do one quick room switch and Surface Pro 3 and other PCs posed some “interesting” AV challenges to get output to the projectors. HDMI seemed to be a particular problem and the AV team was not impressed that many speakers ran Windows 10 build 10532. Apparently VGA remains the lingua franca for AV guys....More

    Updates lay the foundation for the launch of Exchange 2016 3

    Because it’s been a while since Microsoft shipped Exchange 2013 CU9, today’s release of Exchange 2013 CU10 came as no surprise. After all, we have all become accustomed to the quarterly cadence of updates that are required to keep Exchange 2013 servers fully supportable, largely because the last few updates have been easily deployable and high quality....More

    Moving back to Windows Phone 8.1

    Last Friday, I gave up on Windows 10 Mobile (build 10512). The new version of the O/S, which is still very much in beta, had been running on my Lumia 1020 for the last month and had become increasingly unstable. Frequent reboots were necessary to restore normal service and performance was so slow at times that I wondered whether Windows 10 Mobile was wading through treacle. Battery life was another issue and the phone behaved like one of those warming bricks used by climbers and hill walkers to keep their digits toasty. I was an unhappy camper....More
