OK, so if you are like me you have updated to Snow Leopard and have been having to resort to using a virtual machine (not a bad thing) to connect to your companies Exchange 2003 server. Face it, OWA is not good enough for a power user.
I have googled until my fingers have bled and could not find a solution that worked for me…. until now…
I am currently using mac mail, address book and ical to connect to an Exchange 2003 server through the help of http://davmail.sourceforge.net/
Their instructions are out of date as the screen shots are all based off of versions prior to 10.6 but here is where I deviated from what they had:
First get it installed. This part was easy and I just put in the full url that i use in chrome to get to OWA.
Adress Book was the kicker though. The old instructions were way off (although I did finally figure out where Directory Utility is in Snow Leopard (system preferences, accounts, login options, edit network account server, and there she is…)
But the actual fix was quite simple.
Address Book
Add new account:
next is the key because the instructions they have on their website say to put o=od which looked wrong and did not work for me. I had to put Search base to ou=people before things worked. Don’t forget to change authentication to simple and put in domain\user and password…
iCal
For iCal I used CalDAV and the server path of localhost. note: just the username, not domain\user
When you hit create you will get an error, just hit create again.
The server path described on their website was slightly off from what I ended up with.
Just using /principals/users/user@domain.com (where user@domain.com is your default email address on the host).
Don’t forget to change the port to 1080 (or whatever port you put CalDAV on from within DavMail)
Mac Mail
I didn’t have to do anything different from http://davmail.sourceforge.net/osximapmailsetup.html to get mail working.
Having said all this, I will let you guys know how things work over some time but for now I am just happy to have yet another Exchange email account ripped out of windows and placed in my happy Mac world
