Office 365 users can’t see free/busy of on-premises users

The past few days I was working on making an on-prem Exchange Server 2013 SP1 environment hybrid with the Office 365 tenant. You would expect that running the Hybrid Configuration Wizard (HCW) would be it, after setting all the requirements as they should. Unfortunately after running the HCW, Office 365 mailboxes couldn’t access free/busy information of on-prem mailboxes. The other...

From open source groupware solution Zarafa to Exchange: Part 2, Active Directory

See also Part 1: A New Beginning When using Zarafa there are several possible directory services you can use for authentication. I will restrict this post to situations relevant to Active Directory (AD) integration. Even if you did not use Active Directory (or Zarafa for that matter) previously, I believe this post still contains valuable information. Getting to know your...

Behind the presentation: Office 365 apps

Last Monday evening I presented “Office 365 apps” for the Dutch NGN-NGI interest group. And obviously the presentation was interesting, I think a little behind the scenes look for this particular presentation is worth a blog post. Actually, they might complement each other! So, I was asked to present something about apps on an Office 365 themed event. That was...

Disable Offline OWA in Exchange 2013

Although the Offline OWA functionality in Exchange 2013 is a great addition for those that cannot use Outlook (Anywhere with Cached Mode), but are frequently without internet. However, as the browser database in which Exchange OWA stores it’s information isn’t encrypted, it can be a security issue. It can be turned of via the Exchange Admin Center (EAC) via Permissions>Outlook...

Be careful with Outlook customizations! Use AutoDiscover!

During a migration from Exchange 2007 to 2013, we moved several mailboxes as pilot users. Coexistence was fully configured and on my test machine everything worked fine. However, the pilot users had trouble connecting with Exchange 2013 after their mailbox was successfully moved to Exchange 2013 servers. OWA and ActiveSync worked without any hitch. The problem was that Outlook would...

From open source groupware solution Zarafa to Exchange: Part 1, A New Beginning

This blog series will describe my experiences and lessons learned from migrating the Zarafa Groupware solution to Microsoft Exchange, specifically Exchange Server 2013. I’ve done this twice now and although some things are quite obvious, there are some gotchas and it might be a daunting endeavor. A normal transition from Exchange to Exchange already requires good planning, but it is...

Can you use ActiveSync to measure market shares?

Computerworld.com published an article this week called “iPhone, iPad dwarf mobile rivals in small- and mid-sized firms”. It stated: Apple has won the hearts and minds of small- and mid-sized businesses, which have overwhelmingly adopted Cupertino’s mobile devices over rivals powered by Android or Windows, an Exchange hosting vendor said last week. Well, my interest was peaked. Mobile devices and...

Can we expect Exchange 2013 CU3 and 2010 SP3 RU3 soon? Keep watching KB2891587 and KB2892464!

UPDATE 2013/11/20: It looks like the links currently don’t work anymore, possibly because they referenced a non-released update. That’s too bad, but even when the update is not available yet this kind of information is still quite valuable (something I pointed out in a comment on the Exchange Team Blog The Road Ahead post) Just about an hour ago I...
