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 basically the assignment and please notice the very broad scope it could have. That was the first challenge. The first

Does your Office 365 DNS records check fail?

Recently I was working on building an hybrid Exchange 2013 environment. During the setup for specific mail domains, Office 365 didn’t seem to see the DNS records required. In this case it was the SPF record, that would not be accepted. However the record was made as specified as requested, TTL was an hour and after several hours it still didn’t pass the check. Other records made at the same time, were checked okay. Unfortunately that delayed other required changes…

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 Web App Policies and then edit the policies by double-clicking them. Navigate in the pop-up window to Offline Access and

UPDATED 28/3/2024: See update below article. A little heads up. While working on an extensive design including Exchange Server 2013 with Service Pack 1 installed on Windows Server 2012 R2, my eye caught a comment in the Facebook group Exchange Server 2013 (Facebook login required).

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 update its server settings, even though (internal) AutoDiscover worked perfectly. Outlook seemed to retain its settings for Exchange 2007, which

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 even more important when migrating from a third party solution that isn't supported by any available migration tool like Quest.
