It looks like Benny has put a dependency on the Ruby 'premailer' tool 
into his OakMIME Framework but neglected to package a working copy in 
the MailMate application bundle...

Welcome to the wonderful world of the iCalendar/vCalendar standard(ish) 
and it's fantastical interoperability (not "fantastic" meaning "great" 
but rather "a pure fantasy")

Assuming that desktop Outlook sends the same thing Office365 Outlook 
sends (when configured to send as iCalendar instead of a web link) that 
warning is because Outlook sends a mulipart/alternative message with 3 
alternative (i.e. logically equivalent) parts in 3 different formats: 
text/plain, text/html, and text/calendar. MM doesn't know how to present 
a text/calendar part (aka iCalendar, .ics file, etc.) except as an 
attachment, so if you use the "View->Message Body Parts" to show the 
text/calendar you just see an attachment named "Attachment.ics" and no 

As far as I know (and I manage multiple multi-tenant mail systems) no 
other mailer in existence sends event invites/updates like that, however 
it does make a certain logical sense, unlike most of the ways Microsoft 
has sent events around in the past. All MM would have to do to handle 
text/calendar as an alternative part is to extract and display the 
DESCRIPTION field and offer an Attachment.ics attachment as it already 
does (at least in my very limited testing.) If you're seeing a .ics 
attachment, you're not really losing anything by MM not "handling" the

That's odd. I don't use that feature in MM but it appears that anything 
Contacts considers a "Directory" (LDAP or Exchange) works in Contacts 
but not in the Address Panel. I can see my LDAP and Office365 
directories under "All Directories" but they just don't work. So it's 
not just you...
