    Cherish your arbitration mailboxes - just in case! 1

    Arbitration mailboxes made their appearance in Exchange 2010 as a special form of mailbox that is designed to be used by Exchange itself rather than a user. In short, there are times when Exchange needs to stuff data away for one reason or another and it makes sense to use a mailbox for this purpose. After all, mailboxes go in databases and can be protected by high availability, and so on… The full set of arbitration mailboxes is exposed in all its glory by running the command:...More

    Recycled email addresses and Outlook nicknames

    The revelations (last October) that Microsoft is quietly recycling email addresses from its Hotmail, Live, and Outlook.com domains might have come as a surprise to some. According to an email statement from Microsoft to PCWorld.com cited in the article, when an account becomes inactive, “the email account is automatically queued for deletion from our servers....More

    Managing the dumpster - setting quotas for the Recoverable Items folder

    The “dumpster” has been a feature of Exchange since Exchange 2000 to provide a last-chance opportunity for users to recover deleted items without having to ask an administrator to restore data from a backup. The current implementation, introduced in Exchange 2010, uses a folder structure under the Recoverable Items folder rather than a special database view....More

    Understanding the overhead in an Exchange mailbox database

    It’s taken me a while to get around to mentioning the rather useful “Database Growth Reporting” script for Exchange 2010 and Exchange 2013 that was described on the EHLO blog in January.  My apologies for this lapse in service. All I can plead is that other stuff got in the way between now and then and that I never really had a chance to test the code out thoroughly, which is a prerequisite before commenting on software....More

    The ultimate cloud email heresy

    Email systems seem to be in a perpetual state of migration. Since 1996, the on-premises implementation of Microsoft email technology has gone through nine major changes, or roughly one every two years. No sooner are you done and dusted with one migration than the next appears on the horizon. It’s a wonder that we get any real work done at all....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

    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

    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
