Publishing Exchange with pfSense

pfSense is a Linux-based firewall which you can find here.

I wanted to publish Exchange through pfSense. I installed the Squid plugin which includes specific reverse proxy support for Exchange.

If you search for help with publishing Exchange on pfSense you will find this document by Mohammed Hamada.

Email hassles with Android and Exchange: couldn’t open connection to server

I have an Asus/Google Nexus 7 which is set up to receive mail from Exchange 2010.

At least, it was. Some time ago it stopped receiving mail. When the mail client tried to sync, I got this message:

“Couldn’t open connection to server due to security error”.

The message is not particularly clear. I

Fixing a Small Business Server 2008 broken by updates

I had a call last night from a small business whose email no longer worked. They had applied updates to the server but Exchange had failed to restart.

Looking at the services it was easy to see why. All the Exchange services and certain others including the IIS web server were set to disabled:

Windows Phone, Exchange, and self-signed certificates

I am setting up a Nokia Lumia phone, which runs Windows Phone 7.5 “Mango”. I am impressed with the smoothness of the setup experience, though I had one slight hassle which I do not blame on Nokia or Microsoft because it is is not typical.

I run an Exchange Server (and SharePoint) for test purposes

Microsoft Office 365: the detail and the developer story

I attended the UK launch of Office 365 yesterday and found it a puzzling affair. The company chose to focus on small businesses, and what we got was several examples of customers who had discovered the advantages of storing documents online. We were even shown a live video conference with a jerky, embarrassing webcam stream

Notes from the field: migrating a small business to Microsoft BPOS

Today I assisted a (very) small company migrate from Small Business Server 2003 to BPOS (Business Productivity Online Suite), Microsoft’s hosted Exchange and SharePoint.

Why BPOS, when Office 365 launches later this month? Well, BPOS has all the features they need, and when given the choice between a beta-soon-to-be-just-launched online platform, and one that has

Disappearing items in Outlook and Exchange

I came across what looks to me like an unusual bug, most likely in Microsoft Outlook. Background: I have used the Notes folder in my Exchange mailbox for all sorts of information going back several years. This morning, I looked at the folder and found it empty, except for one solitary item. Normally there are

UK business applications stagger towards the cloud

I spent today evaluating several competing vertical applications for a small business working in a particular niche – I am not going to identify it or the vendors involved. The market is formed by a number of companies which have been serving the market for some years, and which have Windows applications born in the

Crisis for ASP.Net – how serious is the Padding Oracle attack?

Security vulnerabilities are reported constantly, but some have more impact than others. The one that came into prominence last weekend (though it had actually been revealed several months ago) strikes me as potentially high impact. Colourfully named the Padding Oracle attack, it was explained and demonstrated at the ekoparty security conference. In particular, the researchers

Exchange 2007: ESEUTIL beats the wizard

Today I was asked to help find missing email in Small Business Server 2008, in other words Exchange 2007. Somehow, thousands of emails had disappeared from a user’s mailbox. They were there a couple of days earlier, so we restored a backup. The procedure is nicely explained by John Bay. You restore the Exchange database
