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 1

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

Office 365 Message Encryption: Protect your email against the spooks

The PRISM revelations have had a huge effect on people generally and on the cloud community in particular. No one really likes the idea of their private communications being intercepted and analyzed and the fact that three-letter agencies were busily tapping into various links to capture data came as an unpleasant and unwelcome surprise, especially to companies considering cloud deployments....More

Deficient IBM and Hitachi 120,000 mailbox configurations 10

Reading the Exchange Solution Reviewed Program (ESRP) page for Exchange 2013, I was taken by the claims advanced by IBM and Hitachi in documents that purport to describe storage solutions capable of supporting the predicted I/O workload generated by 120,000 Exchange 2013 mailboxes. My jaw dropped as I read the documents because both solutions are radically inadequate....More

Managed Folders deprecated in Exchange 2013

In all the fuss and bother around more headline changes in Exchange 2013, such as the introduction of the Managed Store or even Managed Aavailability, It might have missed your attention, but Microsoft deprecated Messaging Records Management 1.0 (MRM 1.0), aka “Managed Folders”, in Exchange 2013. The cmdlets are still available and you can still apply a managed folder policy to a mailbox, but the Managed Folder Assistant will cheerfully ignore that mailbox thereafter....More

Comparing Office 365 numbers to the total Exchange installed base 5

I was struck by the many opinions expressed after I wrote a piece explaining why I do not think on-premises Exchange is dead. Some believed that I am mad and that Microsoft is busily killing one of its larger golden eggs in a rush to convince customers to embrace Office 365 and all things cloud-like. Others thought that my opinion was accurate and that on-premises Exchange would persist for many a long year into the future....More

MEC or TechEd? Austin, here I come...

As Exchange administrators (and their bosses) plan travel and training budgets for 2014, it makes sense to consider the question whether to go to the Microsoft Exchange Conference (MEC) in Austin (April 1-3) or TechEd North America in Houston (May 12-15). For the majority of people it won’t make sense to go to both conferences and Microsoft has certainly not helped anyone by scheduling the two within five weeks of each other....More

Increase in Exchange 2013 mailbox sizes is simply "Store tax"

Why the upper version always wins in mailbox moves 1

Some might be surprised at the TechNet statement about moving mailboxes in Exchange 2013 that says: In Exchange 2013 you must move mailboxes between Exchange 2007 and Exchange 2010 and Exchange 2013 from the Exchange 2013 admin center (EAC) and the Exchange Management Shell....More
