I'm using Apple Mail as my mail program on my MacMini Leopard 10.5.8. I was checking sth out today and I saw that Microsoft Outlook was checked as default mail reader. Thinking that it could be a software related bug, I went to Mail / Preferences / General and clicked Default email reader. In the drop down menu my Mail app was listed. I made the choice then quit Mail. When I reopened it, it was back to Outlook as the default reader. I have Microsoft 2011 on my Mac but never setup Outlook. I migrated from Entourage to Mail about 2 years ago and that's it. Can someone please tell me what is going on?
