Why an Office 365 update caused the Exchange 2013 HCW to crash 1

The publication of KB2988229 on July 30 and an accompanying EHLO post provided formal acknowledgement that a problem exists with the Exchange 2013 Hybrid Configuration Wizard (in all supported versions of the product)....More

Exchange 2007 approaching the end of the line - slowly 1

Alongside the release of Exchange 2013 CU5 on May 27, Microsoft also issued roll-up update 6 (RU6) for Exchange 2010 SP3. The new update contains no security fixes and should therefore be relatively straightforward to put into production, subject to the normal caveat of test before deployment....More

Office 365 by the numbers - an ever-increasing trajectory

Last November, I attempted to figure out how many Office 365 paid subscribers Microsoft had signed up on the basis of their reported $1.5 billion annual run-rate (at the time). I concluded that some 15.625 million paid subscriptions were in place on the basis of an average $8/month fee....More

Yammer - a technology still looking for a solution? 3

The news that Yammer co-founder David Sacks is leaving Microsoft comes as no surprise. It is the nature of the beast that those who create a technology usually leave soon after that technology is bought and absorbed by a larger company. After all, they have lost control of their creation and have been richly compensated for that fact. Moving on to a new challenge is a natural reaction....More

The changing nature of email NDRs

We’ve all received NDRs, or non-delivery reports, the way that email servers attempt to be friendly to users when informing them that their email has not been delivered. NDRs have been with us since the very early days of email and several Internet Task Force (IETF) Request for Comments (RFCs) have addressed the need for email servers to generate NDRs in a common format. Given the use of SMTP as the de facto email connectivity standard for many years now (does anyone still use X.400?), you’d expect that NDRs would be a well-rounded feature of any self-respecting email server....More

Challenges await as Microsoft dumps MEC, TechEd (and other conferences) for a mega-event 4

Microsoft has announced their intention to run a unified technology event in Chicago in the first week of May, 2015. The new event will replace the previous Lync, SharePoint, Exchange (MEC), Management Summit, TechEd and Project conferences. In short, it’s the mega-conference, a new event that combines technology updates for all of the Office servers plus MMS, which seems like a curious add-on to the Office fold....More

Protect users by suppressing Outlook's conflict resolution reports

Outlook Apps - a new approach worth considering 1

A conversation with a Microsoft engineer at the Microsoft Exchange Conference caused me to wonder if Outlook apps are being overlooked by many companies as they seek to extract value from their deployments. Or indeed, to justify an upgrade to the latest generation of Microsoft Office technology....More

Microsoft Learning insults Exchange professionals with simply awful video 3

After viewing their latest video, posted on July 14, that announced that the Exchange 2013 certification exams have been updated for Exchange 2013 SP1, I conclude that the people running whatever part of Microsoft Learning (MSL) that is responsible for this production have been exposed to some potent mind-altering material....More

Inconsistent searches all too commonly seen in Exchange

The topic of searching mailboxes came up during the second “Experts Unplugged: Support Issues” session at MEC. In a way it had been covered before at the conference because Microsoft had acknowledged that deficiencies exist in this area and that they are busy developing more precise and effective search capabilities. Apparently the new search will appear in Office 365 towards the end of 2014 and in the next major release of Exchange sometime at the end of 2015....More

Security Design Change for Office 365 Public Folders Causes Inbound Email to NDR 1

Keeping up to date with what's been happening with Set-MailboxDatabase

No matter how long you work with software, it’s impossible to master every possible detail, especially when you’re talking about a complex product like Exchange 2013. Which brings me to reveal two small, but to me, interesting changes that have occurred recently. I say “recently” because I am not quite sure when Microsoft made the changes, but that hardly matters in a world when frequent updates are expected....More

Is Microsoft really saying "don't virtualize" Exchange? 4

Microsoft’s embrace of simplicity in all things to do with Exchange 2013 might have the unexpected side-effect of turning customers away from virtualization. If so, it will reverse a trend that had gathered pace ever since Microsoft first saw the light of the virtual day after Hyper-V appeared....More

Nothing to fear in MAPI over HTTP 1
