I've recently made the jump from Leopard to Snow Leopard and, with it, have been able to move from Microsoft Entourage to Mail.app / iCal (Snow Leopard provides better Exchange support, which means iCal should now allow things like viewing other people's schedules). After the initial jubilation, it turns out that things aren't quite that rosy after all. So I thought I'd capture what the down points are in case anyone is considering a similar move.
I've actually found Mail and iCal to be a bit clunky.
- Messages that have been sent have still been saved in draft, and sometimes didn't appear in the sent folder. This led to me sending messages a second time, causing confusion. Sometimes these messages were incomplete, because the draft had been saved before the message was completed.
- There's been at least one occasion where I sent a (very important) message but all evidence of it has disappeared, even when I use Webmail to look directly on the server.
- Sometimes i've tried to delete a message from drafts but Mail.app wouldn't let me, claiming that it couldn't connect to the server. Yet I was able to carry on sending and receiving other emails with no problems. The only way to remove it was to send it!
- In iCal, when changing a meeting, it seems to struggle when looking for certain invitees using auto-complete, even when the recipients are all on the same domain
- Entourage used to give frequent recipients in my address book priority over those I never email (who just happen to be in my domain). Annoying because for Stephen Waller (with whom I share a project), I have to type "Stephen Wal", because there is something else in the org whose name starts with "Stephen Wad".
- When changing / removing an event in iCal, you have to inform all participants / the meeting organiser - you don't have an option not to send a message. Annoying as I sometimes want to remove or change something in my calendar without sending the organiser an email.
These are just the ones I can think of off the top of my head. There are others.
Anyway, I never thought I'd say this, but I'm seriously considering moving back to E-Rage - sorry, Entourage. Not cool.
