Changing circumstances make it difficult to measure adoption rate for Exchange 2013

A journalist asked me whether companies are deploying Exchange 2013 faster or slower than previous versions and what reasons are driving its adoption. I thought about the question a little and then replied that it is impossible to compare the adoption rate of one Exchange version against another because of the different circumstances that surrounded each release. Here’s what I meant....More

Does anyone care that the Exchange 2013 Edge Transport server role came back? 5

When Microsoft shipped Exchange 2013 RTM, they forgot to include the Edge Transport (ET) role in the set available for deployment. Or maybe they omitted ET on purpose. In any case, customers were instructed that they could continue to use the Exchange 2010 version of ET and all would be well. And it was. That is, if you ignore the complaints....More

Exchange Online increases eDiscovery mailbox limit and boasts better performance too

The Office 365 Roadmap is a great place to look for information about what’s coming up in the cloud-based versions of the Office servers and potentially new versions of their on-premises counterparts. Browsing the “Rolling Out” section recently, I noticed that an entry saying “Exchange eDiscovery mailbox search limit increased to 10K mailboxes,” which prompted some investigation....More

Software magic behind Office 365 Groups document libraries

The new Office 365 Groups feature includes “Files,” a library intended to hold documents of interest to group members. The implementation of Files has not been without its problems and I received some criticism after publishing an article on the topic because of the way that I referred to OneDrive for Business in the text....More

Exchange 2013 CU7 debuts along with security fixes and updates for Exchange 2010 and Exchange 2007 2

Exchange 2013 CU6 appeared on August 26 Eleven weeks later Microsoft was all set to release Exchange 2013 CU7 until some late-breaking issues forced the correct decision to delay CU7 until everything was right. A month on, build 1044.25 (KB2986485) is now available for your download pleasure. The usual and hopefully now-well understood caveat that you need to test any new build of Exchange thoroughly before deploying it into production applies to CU7....More

Grading Exchange 2013 in the two years since RTM

Microsoft formally released Exchange 2013 (the Release to Manufacturing or RTM version) on December 3, 2012. For those who care about those things, the RTM build number was 516.032. Today, with Exchange 2013 CU7, the build number is 1044.xx. The question is how has Exchange 2013 done over two years, seven cumulative updates (including one formal service pack), and a difference of five hundred-odd in builds.   ...More

A clash between S/MIME and transport rules

S/MIME support for Outlook Web App (OWA) is one of the resurrected features that makes its appearance in Exchange 2013 SP1. It’s much the same functionality as exists with Exchange 2010, with the exception that only recent versions of Internet Explorer (IE9 and above) are supported....More

OWA updates in Office 365 help with Chrome showModalDialog issue but no joy for on-premises versions 2

By now you’re probably well aware that Google deprecated the showModalDialog method in version 37 of their Chrome browser to cause some problems for Outlook Web App (OWA) and Exchange Administration Center (EAC), both of which use the method to display modal screens to collect user input. Well, there’s good news and bad news on that topic....More

Forcing Exchange's Admin Center to use a specific language

  Exchange 2010 SP1 introduced the capability of allowing administrators to run the Exchange Control Panel (ECP) without requiring their account to be linked to a mailbox. This is a big deal for many companies who require people to access their email using “normal” or unprivileged accounts and don’t want administrators to use their mailboxes when logged in with elevated permissions....More
