Thunderbird and Exchange

This morning a friend was complaining on Twitter about using Evolution on Linux to talk to his company’s Exchange server. Evolution is the default answer to the question “how do I talk to Exchange from Linux”, but my past experience has been much like my friend’s – it’s really not a very good answer.

I suggested Thunderbird to him. In my opinion, Thunderbird is the best email program out there. It’s been my email program of choice for several years. It will happily work with Exchange to receive and send email. Googling for “thunderbird exchange” will bring back lots of useful results.

But Exchange isn’t just about email. There’s a whole calendaring system there too. Evolution supports that, but (by default) Thunderbird doesn’t. There is, however, a way to get your Exchange calendar into Thunderbird using a rather circuitous route. Here’s how I do it.

Firstly, you need the Lightning add-on for Thunderbird. Lightning adds calendar features to Thunderbird. You can create events and get alerts when they are about to happen. You can even subscribe to external calendars as long as they are in a standard format. Unfortunately, Exchange calendars aren’t in standard formats. So we need some kind of intermediary.

The intermediary I use is Google Calendar. In fact I use Google Calendar as my definitive calendar. Every other calendar application I use reads from or writes to my Google Calendar. And Thunderbird (or, rather, Lightning) is one of the applications that interacts with it. Google Calendar writes calendars in the correct standard format, so Lightning will read a Google Calendar out of the box. But we can get cleverer than that using another Thunderbird add-on called Provider. Once Provider is installed, communication between Lightning and Google Calendar becomes two-way. I can add events either in Lightning or in Google Calendar and they will turn up in both.

There’s one final step. We need to synchronise our Exchange calendar with Google Calendar. And Google have a product that does just that. It’s called Google Calendar Sync. With this installed, your Exchange calendar is automatically synchronised with Google Calendar regularly. So now we can edit our calendar anywhere and the new or updated events will show up in all of our calendars. I’ve even noticed that invitations to events from other Exchange users show up in Lightning – but I haven’t tried replying from there yet.

There are two things I don’t like about Google Calendar Sync. Firstly, it has to be running on a PC running Windows which is connected to your Exchange Server. So it’s not a solution that will work whilst you’re (for example) out of the office with your office PC switched off. Secondly, it will only sync with your main Google Calendar. I would have liked to have a separate calendar for work events (and it’s only work events that come from my Exchange calendar), but that doesn’t seem to be supported yet.

And there are a couple of caveats with Lightning and Provider. If you’re using a Beta test version of Thunderbird 3 then the standard Lightning and Provider downloads don’t work with it. There are nightly builds of them both available, and the version of Lightning that I tried worked fine but Provider still didn’t seem to work. I expect that situation to change quickly over the next few weeks as the Thunderbird 3 launch gets closer.

A year ago I was really disorganised. I never knew what I was supposed to be doing. Settling on Google Calendar as a definitive place to plan my life was a really good idea. At least now, I know which meetings I’m missing.


Admitting Your Mistakes

When did it become unfashionable to admit to mistakes. We all make mistakes. Why not just own up to them?

Yesterday I got an email from an agent asking if I was available for work. I replied pointing her to the page on my company web site where that information is always available.

Just now I got the same email again from the same agent. Well, the content was identical, but the subject line had changed. Yesterday it was “New Year New Project?”, today it had become “New Projects?”.

I replied to the second email saying that my situation hadn’t changed in twenty-four hours. Her reply to this was:

So sorry for some reason it looks like my outlook has duplicated my emails

Not, “oops, I looks like I sent stff to the same people twice” or “sorry, I should have checked that list of names more closely”. Just “my outlook has duplicated my emails”. It wasn’t her fault – her technology had let her down. Everyone knows that Outlook often sends the same email twice, twenty-four hours apart and changes the subject line as it does it.

Except it doesn’t, does it. I know that Outlook is one of the most broken email clients ever to have been released (only beaten, in my experience, by Lotus Notes) but last time I used it, it wasn’t in the habit of changing subject lines and resending mail. Maybe that’s a new feature.

I pointed out the subject line discrepancy and she replied that she was not “great with Technology!” Which, I suppose, is as close as I’m going to get to an explanation.

Perhaps blaming mistakes on a “computer error” still fools most of the population. But if you’re dealing with IT people, you must realise that most of them will know more about the subject than you. And that must make blaming the technology an extremely risky approach.

It’s certainly one that has moved this recruiter along way down my list of people I want to do business with.
