I'm using Mac Outlook as my primary email program (my company uses Exchange and it's the "supported" program on Mac), but I've configured Contacts/Calendar to also talk to the Exchange Server.

I like the way Calendar handles alerts, and the fact that it can send email reminders, but I'd need them to be sent via Outlook as I'd rather not have 2 copies of my Exchange Inbox on the disk (to save space).

Is there a way to tell Calendar to use Outlook for outgoing email? For now, it asks me to configure Mail.app every time I set a reminder to send email.

  • Either you dummy configure Mail so you can access Preferences from the Mail menu and set in the General" pane your default email reader (if not working from Outlook preferences).

  • Or you may type in the following in Terminal:

    defaults write com.apple.LaunchServices LSHandlers -array-add '{ LSHandlerURLScheme = "mailto"; LSHandlerRoleAll = "com.microsoft.Outlook"; }'

    This should add an entry to the "~/Library/Preferences/com.apple.LaunchServices.plist"

    Using Xcode you add a dictionary item with the two following items:

  • Using RCDefaultApp could do the trick but since it hasn't been update since 2009 I'm not sure it's still working.

  • Thanks for the suggestion, but it seems that mailto: is already configured properly as typing "mailto:[email protected] in the address bar of the browser (or running the command "open mailto:[email protected]") gets me a blank Outlook message with the address in the to: field...

  • I've also configured a dummy account in Mail to get to the pref pane and the default Email reader is set to Outlook

  • To top it off, leveraging your suggestion, I've run the command defaults read com.apple.LaunchServices LSHandlers and the result for mailto: is already what you suggested as a value: { LSHandlerRoleAll = "com.microsoft.outlook"; LSHandlerURLScheme = mailto; },
