Long story short - I work on a Mac laptop. Many of my clients (some tiny, some big corporations) are on PC.
I'm having issues with email meeting requests, specifically cancellations/changes.
I purchased Outlook for Mac 2011 hoping it would help, but so far it's just causing other problems, and now there are sync issues with iCloud.
From everything I've read, there's really no way to resolve this.
My clients' IT departments won't help me since it's my own equipment.

My question - should I just stick with Mac mail, since everything else I do is Mac (iphone, all my programs, etc.)

Or is Outlook a better mail program?

What do other freelancers use?
Thanks so much!
