    The path to native high availability for Exchange 1

    I received quite a few notes after recent posts covering how Exchange’s storage demands have evolved over the last decade and what this means for third-party vendors who sell high-end storage. Some pointed out that the storage vendors won’t mind too much if some of their market has disappeared because Exchange now favors JBOD....More

    Lots of Exchange on-premises updates to install 4

    Microsoft launched Exchange 2016 on October 1, 2015. Five-and-a-half months later Exchange 2016 has its first cumulative update (CU1) along with a batch of other updates – Exchange 2013 CU12, Exchange 2010 SP3 RU13, and Exchange 2007 SP3 RU19....More

    Exchange 4.0 cleared to fly 20 years ago today 8

    I awoke this morning to a note from Iain McDonald to remind me that it was twenty years ago today that Microsoft approved the release of build 837 of a new product called Exchange Server. After being signed off in March 1996, the formal launch happened the following June. It took time to get the “gold” build sent to manufacturing so that copies could be distributed to customers plus all the ancillary activities such as marketing....More

    The @ legacy of Ray Tomlinson 1

    I was sad to learn of the death of Ray Tomlinson on March 5. For those who don’t know, Ray was the engineer who figured out how to send email between computers in 1971. Part of that effort was the selection of the at sign (@) as the delimitation between personal account name and email domain for addressing messages....More

    The downside of being a filer and other reasons why Outlook's cached limits might bite you 6

    One of the points I made in “How Exchange’s Recover Deleted Items option could be improved” is that it would be nice if Exchange could track the folder that an item was deleted from so that the item could be restored there if required. Some said that this wasn’t needed because they never use anything but the Inbox and Sent Items folders....More

    Exchange mailbox anchoring runs into stormy waters 1

    When Microsoft announced that Exchange 2013 CU11 and Exchange 2016 CU12 would implement a “mailbox anchoring”, a new way of connecting Exchange Management Shell (EMS – or PowerShell if you like) sessions to Exchange servers, I weighed in with some thoughts on the topic and basically said that the new approach was a good idea....More

    How many ways can Outlook archive an item? 2

    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

    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

    Why public folder compliance gets no respect 1

    Microsoft’s July 2 announcement of a “compliance toolset” for public folders appears to have fallen flat in terms of the excitement generated in the Exchange community.  At least, I never hear anyone talking about it or receive any questions about why Microsoft’s compliance toolset for the cockroaches of Exchange is so limited....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

    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
