I had a play with Windows Live Calendar and I quite liked it. Having the connector would make it seamless to share calendar items. So I downloaded and installed it. Ran up Outlook and it crashed. Try again. Crash. Uninstalled the Outlook Connector and it still crashes. But at least now I can see some details – it seems to be crashing due to my LinkedIn toolbar add-in.
So I start in Safe mode (just hold down Control when you start Outlook) and disable the LinkedIn add-in. Everything is back to normal.
Now, I’ve been using the LinkedIn toolbar for a while with no problems, so I can only assume that both it and the Outlook Connector share some DLLs and the Connector install has put on a different version to the one the LinkedIn toolbar was using.
Anyway, lesson learned – always be careful with Beta software…
UPDATE: To clarify: I wasn't able to get both the Outlook Connector and the LinkedIn toolbar to work. I had to choose one of them and keep the other disabled.
If you are brave you can download the Outlook Connector here.
