Blocking iOS 7 in Exchange 2010 & 2013 (updated)

Now that iOS 7 available, it might be interesting to know how to block this version. In the past there were some issues with the Exchange ActiveSync implementation in specific iOS DeviceOS versions (read this and this). Please note that I did not encountered or heard of any ActiveSync issues with iOS 7, but it might be prudent to be prepared. But first we have to find out which DeviceOS versions are already present, or how they are presented to

My portable lab hardware

Recently somebody asked via Twitter my what the make and model is of my laptop, used for Exchange testing environments. Well, 140 characters is not a lot of space so I decided to blog about it. Our company uses Dell laptops as a laptop standard, but other vendors might have comparable configurations. The main model type is a Precision M4700, but for lab purposes the configuration has been customized: CPU: Intel Core i7-3820QM @ 2,70GHz Memory: 32GB (4x8GB) 1600MHz DDR3

Script converting Mail-User to Mailbox-User

Not all organizations need to have every user to be mailbox-enabled, sometimes a mail-user (also referred to as mail-enabled user) with a forwarding SMTP address to an external mailbox is enough. However, it is surely possible that the requirements over time change and the mail-enabled user does need to be mailbox-enabled, making use of the calendar or perhaps even more efficient use of Lync integration. However, converting a mail-user isn’t just changing the RecipientType of the account. First the users

Simplifying the OWA URL with Citrix Netscaler

Load balancing Exchange 2010 with Citrix Netscaler using Content Switching

Next to F5, KEMP technologies and a lot of other network load balancing vendors there’s also Citrix with it’s Netscaler brand. Especially when an environment also has Citrix servers, it could mean that well scaled Netscaler devices are present and can also be used for other purposes next to Citrix Secure Gateway access. Obviously Exchange 2010 comes to mind. Citrix already has a very helpful Netscaler Exchange 2010 deployment guide (PDF warning). But unfortunately that guide is not always something

Managing mailbox storage with Exchange 2010, Part 3

In the previous part one and two of this series, I’ve discussed using PSTs, Exchange Personal (on-premises) and On-line Archiving as well as third party solutions.

Retention Policies The basic Messaging Records Management functionality behind Retention Policies isn’t actually that new. In Exchange 2000 and 2003 you could

Exchange and malware protection

This blog post is something I intended to write for a while now, because it is a question that i get asked a lot. On which Exchange server roles do you need to install the Exchange malware protection software, be it the now no longer for sale Forefront Protection for Exchange or similar products from McAfee, Symantec or GFI and the like. Why is this IMHO a valid question? Well, if we ignore the Microsoft recommendation to install multi-role servers

Managing mailbox storage use in Exchange 2010, Part 2

In the previous part (yes, I know. It’s from May… I’m very ashamed) I discussed using PSTs or the built-in Personal Archive (also referred to as Online Archive). In this post we will discuss third party archiving solutions and Exchange Online Archiving which in this case is service part of Office 365, although you can mix it with an on premises solution. (see the possible confusion) Third Party Archiving As it seems, organizations had long ago issues with overflowing Exchange
