    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

    Understanding what the Exchange 2016 Preferred Architecture really means 1

    The notion of “best practice” has long been an elastic commodity when applied to Exchange architecture and design. Consultants and consulting companies have professed to have their own magic method to ensure the successful deployment of Exchange since the first version appeared nearly twenty years ago. There’s nothing harmful in following a successful recipe. Problems only appear when people refuse to change the recipe to reflect new developments....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

    ESEUTIL - even more evil for DAGs

    All of the comments I included in my post “ESEUTIL – the evil utility” apply to both standalone servers and those who are members of a Database Availability Group (DAG). I bet you wouldn’t be surprised if I told you that there’s even more to consider when you contemplate running ESEUTIL against a database that has copies within a DAG....More

    Removing on-hold items from Exchange and SharePoint: unsupported but doable

    The usual reason for placing a mailbox on hold is to retain its contents for some legal or regulatory purpose. However, the situation might arise when it is necessary to remove some items from a mailbox that is on hold. For instance, someone might successfully sue your company to demand the removal of all information pertaining to them or some particular activity. If ordered to permanently remove the material, there is little you can do but comply....More

    New report slams Office 365 compliance features unfairly 2

    Compliance is a pretty big deal for many companies, especially those who operate in regulated industries. Almost every jurisdiction mandates that companies preserve certain records related to their business dealings. Given the widespread use of Exchange and SharePoint for communications, it should come as no surprise that Microsoft has invested heavily in building compliance features to support their use in business operations....More

    The unnecessary renaming of Outlook Web App 3

    The news that Microsoft is introducing a set of changes into their web client for Exchange Online was expected. After all, many of the changes described in yesterday’s Office blog post are already available in Exchange 2016 Preview, which must have set a new benchmark in terms of on-premises software receiving new features ahead of the cloud....More

    What you should do to secure mailboxes when employees die

    Securing an Exchange on-premises mailbox after an employee is fired 3

    Securing information after someone is fired (in HR terms, let go with good reason) is often important, especially if the now-terminated employee is suspected of some form of misconduct.  Exchange 2010 and Exchange 2013 offer a range of methods to secure and protect mailbox data but software features are useless unless they are executed properly within a well-documented and tested process....More
