Why I needed to use Outlook Web App's in offline mode instead of Outlook

I've made lots of comments about Outlook Web App (OWA) recently. Justifiably so, I think, seeing that I have actually been using OWA more than I usually do and Microsoft released their OWA for iOS apps....More

Service packs and cumulative updates make my head dizzy 2

Now that the dust has settled around Microsoft’s announcement that Exchange 2013 Service Pack 1 (SP1) is on the way in “early 2014” along with updates for the other server applications in the Office suite, it’s probably a good time to reflect on the changing nature of service packs.<...More

Counting Client Access Licenses 5

Client Access Licenses (CALs) have a reputation for being difficult to figure out. Two exist for Exchange – the standard CAL that covers access to the basic feature set (such as being able to send and receive email) and the enterprise CAL, or eCAL, that licenses extended features such as in-place eDiscovery holds, customized ActiveSync policies, Unified Messaging, or Data Loss Prevention (DLP). The eCAL is additive to the standard CAL, so if you have an eCAL, you can use any of the functionality that exists in Exchange....More

Server heal thyself - Managed Availability and Exchange 2013 3

Returning to the topic of Managed Availability, in my last post I covered the logic and rationale that drove Microsoft to develop and implement such a capability in Exchange 2013 (and, possibly more importantly for their own purposes, in Exchange Online). This post looks at the implementation and how successful it has been to date.  ...More

The need for Managed Availability

As we start off in 2014, I thought it would be a good idea to look back at technology that gained increasing visibility during 2013. In terms of Exchange, there’s really only one candidate in that space: Managed Availability, otherwise known as the “Rodney Dangerfield” of the product (the reader is invited to figure out that analogy for their own amusement). I’ll cover the topic in two posts: this will cover the logic and rationale behind why Managed Availability exists....More

Some well-loved Exchange products expire in 2014 - or at least, their support expires - time to upgrade! 4

As we enter 2014, I’m sure that you are all looking back on 2013 and wondering how the year went by so quickly. For many, it was time to begin the process of finally bringing Exchange 2013 into production after Microsoft released the necessary updates for Exchange 2007, Exchange 2010, and a set of cumulative updates, the latest of which (Exchange 2013 CU3) seems to be pretty stable and dependable.  ...More

Ten predictions for the world of Exchange in 2014 5

2013 seemed to go by in a flash as I was busy most of the year. Well, busy in my context, which means that I ended up doing stuff that I like to do, such as writing this blog. With that in mind, here are some thoughts on what I think will happen during 2014:...More

Not always straightforward to calculate the costs of moving on-premises email to Office 365 2

I received lots of comments and email after I posted details of my support experience with an Office 365 upgrade from Wave 14 to Wave 15. Thankfully everything was restored to full health once the problem was escalated within Microsoft and I have enjoyed using the Wave 15 version of Office 365 ever since....More

Running Exchange 2013 on Amazon Web Services 3

ADSIEdit solves yet another problem for Exchange 2013 mailbox servers 3

Proving once again the usefulness of ADSIEdit, the “brain surgery” utility that fixes many problems in Active Directory, we see how KB2897047 describes using ADSIEdit to fix a small oversight that might have crept into Exchange 2013 servers after they had been upgraded to CU2 and indeed, an issue that might have persisted after the servers had been upgraded to...More

How Exchange 2013 measures and monitors server health 2

The discussion about Managed Availability and its use of Performance Monitor to gather and measure data relating to Exchange 2013 server health prompted a question about how many probes does Exchange 2013 deploy to assess how well its components are working....More

Office 365: a kind of dogfood environment for on-premises Exchange 2

You might have been puzzled by the statement “If you want clues about what’s coming in the next version of Exchange Server, keep an eye on what’s happening in Office 365” contained in Microsoft VP Perry Clarke’s attempt to pacify the on-premises community. Where does one look for clues in Office 365? Does Microsoft say where the new bits are? And would you know a new feature if you saw it?...More

What question would you ask Microsoft's Exchange development supremo? 20

I need your help. Next Friday (December 13), I shall interview Perry Clarke, Microsoft CVP for Exchange development (in other words, Perry is responsible for every bit of code written for Exchange, both on-premises and cloud). I have known Perry for many years and have quite a few questions to ask him about the future direction of Exchange and other issues, but I thought that I’d open it up to the Exchange community and invite you to submit questions that you’d like me to ask Perry....More

How nice: Microsoft is now monitoring my Office 365 email

I hear that the much-trumpeted doubling of Exchange Online mailbox sizes to 50GB isn’t going to plan and not all tenant domains will be upgraded to the new quotas by the end of 2013. The new date is apparently “by the end of the first quarter of 2014”, which is soon enough. I cannot imagine that there are hordes of Office 365 subscribers waiting to stuff their mailboxes with sufficient junk to fill the new quotas....More

Exchange 2013 CU3 causes headaches for OWA on Windows XP

The release of Exchange 2013 CU3 might just be the call to action to replace old browsers. Some early deployments (mostly test so far) have reported severe performance problems with Internet Explorer 8 (IE8) and Firefox version 24 when running Outlook Web App (OWA), with the likely culprit being some JavaScript problems that cause memory leaks and poor performance....More

Wave 15 Office 365 admin interface unifies applications but lacks some functionality 4

The administration interface for the Wave 14 (Exchange 2010) version of Exchange Online is a modified version of the Exchange Control Panel (ECP), also found in on-premises deployments. A radical change occurs when Office 365 tenant domains are migrated to Wave 15 as no trace is to be found (without looking) of the Exchange Administration Center (EAC), the on-premises admin interface for Exchange 2013....More

Kitkat causes ActiveSync headaches for Android users 2

As you probably realize, many of the mobile device vendors who create tablets and smartphones running the Android operating system license it to connect to Exchange using ActiveSync (EAS).  And despite the differing implementations of email clients on the various Android devices, most of the time connections are easy and reliable, which is exactly how you’d like them to be....More
