Wrapping up Exchange Connections 2014

Returning from Exchange Connections after a busy week in Las Vegas. The sessions were superb and we had great speakers, including a cast of well-known Exchange MVPs who fully lived up to their reputation for independent advice. We also had some great sessions delivered by Tim McMichael and Wes Blalock from Microsoft. And of course, as is normal at a technical conference, everyone worked extremely hard and no fun at all outside the sessions was had by anyone....More

Product quality and functionality gaps top-of-mind issues at Exchange Connections

Google kills showModalDialog API in Chrome 37 and does evil to Exchange 5

Google, that well-known purveyor of the “don’t be evil” slogan, certainly cast the evil eye on Outlook Web App (OWA) and the Exchange Administration Center (EAC) when it changed version 37 of the Chrome browser (both 32-bit and 64-bit) to deprecate the showModalDialog method, which creates a modal dialog box that retains input focus while open....More

Office Delve debuts to help Office 365 users find information again 3

New technology is like a new car - it smells nice and you don't know what all the buttons do. As time goes by, the technology becomes lived in and you know its flaws and weaknesses as well as its strengths. And so it is with Office Delve, now available to the First Release group within Office 365 to liberate users from the tyranny of not knowing where their information is stored. I hope it does well, but it's early days yet......More

Yet another co-existence bug in Exchange 2013 CU6 causes ActiveSync failures for Exchange 2007 users 2

Just when you thought it was safe to go back into the water because Microsoft had moved swiftly to fix the hybrid connectivity and Exchange 2007 Store interoperability bugs that afflicted Exchange 2013 CU6 since its release on August 26, news comes of yet another problem....More

Why Exchange 2016 will be coming to you soon 2

All of the hoo-hah that occurred at the recent Microsoft Exchange Conference around the many wonderful things that will soon appear in Office 365 as described in Microsoft’s “Evolution of Email” post will have fallen on stony ground for some. Those of us who use Office 365 will, of course, have no opportunity to vote on the matter because we have to accept the functionality provided in the service....More

Microsoft fixes hybrid connectivity problem in Exchange 2013 CU6 2

Microsoft has published KB2997355 to provide a script fix for the issue that plagued Exchange 2013 administrators when they found that they couldn’t use the Exchange Administration Center (EAC) to manage Exchange Online mailboxes after deploying Exchange 2013 CU6....More

Exchange 2013 CU6 hybrid and co-existence bugs cause administrators to despair 1

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

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
