    OWA bug compromises item preservation for litigation and in-place holds

    Microsoft has confirmed that a bug in Outlook Web App (OWA) can be exploited to compromise in-place or litigation holds. The bug means that a user can remove items from their mailbox without Exchange tracking that action and preserving copies of the items. All other clients work properly – the problem is only with OWA. However, it affects Exchange Online (Office 365) and all supported versions of Exchange 2013, including the recently released cumulative update 6 (CU6)....More

    Exchange 2013 Cumulative Update 6 begins to address public folder scalability

    The release of Microsoft Exchange Server 2013 Cumulative Update 6 (CU6 – build 995.29) comes as the summer vacation period winds down. Still, attention might still be more focused on the pressing matters of vacation, cold beer, and ice cream and not on having to upgrade email servers....More

    TechEd Europe session selection not good news for on-premises customers or independent voices 5

    Those of you who plan to go to TechEd EMEA in Barcelona at the end of October might be disappointed to discover the lack of independent advice that exists at the conference regarding Exchange and associated technology. The Exchange MVPs, many of whom live in Europe, are also disappointed because Microsoft declined every MVP-led session that was proposed, most of which were submitted by speakers with strong track records of successful presentations at different events....More

    Another opportunity for automation in eDiscovery for SharePoint 2013 and Exchange 2013

    Why is it that anything that involves co-operation between Exchange 2013 and SharePoint 2013 is quite so hard to setup and fragile to manage? It’s almost as if the two products are the result of work done by two very different development groups rather than part of one great big happy “Office Servers” family....More

    The joy of an impractical 100,000 Exchange 2013 mailbox configuration 1

    Last November, I wrote about some configurations advanced by Hitachi and IBM that appeared to meet the storage needs of 120,000 Exchange 2013 mailboxes. In a nutshell, I didn’t think too much of the configurations because they featured Database Availability Groups (DAGs) that deployed only two copies of each mailbox database. That just doesn’t make sense in any way if you want to run such a large Exchange deployment....More

    Rapid development in Office 365 reflects current software engineering practice

    The old carefully-paced world of software engineering worked well at a time when everyone accepted that it took time to design, program, test, and ship good software. It is a different matter today when any self-respecting web site is deemed static and perhaps even stagnant if it is the same from one week to the next....More

    Update causes Outlook 2013 to fail to open archive mailboxes 5

    I don’t tend to pay much attention to my archive mailbox. It sits there in the list of resources opened by Outlook but I never really feel the need to go and check that the Managed Folder Assistant (MFA) is moving items to the archive in accordance with my retention policy. It just happens, and like most users, I just let it happen and forget all about the items that accumulate in those archive folders....More

    2TB seems like such a good size for a mailbox database 3

    I am sometimes asked about how large an Exchange mailbox database should be allowed to grow. In an era of ever-swelling mailboxes, it’s a good question. After all, if you’re going to indulge users with 100GB mailbox quotas, you have to figure out where those mailboxes will be stored....More

    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

    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
