Managing Mailbox quota’s: databases with different settings?

So, a while back I discussed an on-premises Exchange design for a customer. When discussing database distribution in an Exchange 2013 Database Availability Group (DAG), the topic of mailbox quota’s came along. They insisted on having different Database (DB) level quota’s and move mailboxes to other databases when the user requires more storage space. It’s a tactic I have seen...

Legacy Public Folders to Exchange 2013 migration tips

A couple of weeks ago I performed a Public Folder migration from Exchange 2007 (aka legacy) towards the modern Public Folders of Exchange 2013. As you may know, the traditional migration method using Public Folder replica’s isn’t available due to a radical redesign of the Public Folder architecture. Instead of dedicated databases, the hierarchy and data are now stored in...

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...

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...
