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.

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. In this last post I will discuss the use of Retention Policies and Mailbox quota’s in order to manage storage usage. As a bonus I will shortly discuss improvements in Exchange/Outlook 2013. 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

Using the Microsoft Connectivity Analyzer Tool

Recently Microsoft released an updated version of the Microsoft Exchange Remote Connectivity Analyzer rebranding it as the Microsoft Remote Connectivity Analyzer as it now also can test Lync connections, next to Exchange and Office365. Another addition is the Microsoft Connectivity Analyzer Tool, a local variant of the online tool for Exchange connections. This is a very helpful tool for internal testing and despite being in beta, it already successfully helped me correctly identifying a certificate issue before I used it

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

The Windows 8 Mail app

A few hours back the Microsoft Exchange team published a blog post on how to connect and support your Windows 8 Mail app with Exchange. It has a lot of good info on which Exchange ActiveSync (EAS) policy settings are supported and how the App reacts. Most of those things I already discovered in earlier blog posts of mine, using the Windows 8 Consumer Preview. It seem as if there are no massive changes since then. But I did dig

Microsoft announced yesterday new approach regarding the validation of certificates coming in august this year. Certificates with a key length less than 1024bit will be blocked: Adding to our defense-in-depth measures, in August, we will release a change to how Windows manages certificates that have RSA keys of less than 1024 bits in length.
