    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 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

    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 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

    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
