Mail.app keeps multiple copies in Draft and does not delete after send
I have just recently noticed this problem and it seems to be getting worse. I am on Mountain Lion 10.8.1 and I'm using an exchange server (2010) email account.
I do not recall this problem being this bad in Lion. When I save a draft go back into it, make changes, it saves a bunch of copies. I just deleted about 30 emails from one draft.
The 2nd issue is it does not leave the draft folder when I actually send, so it appears I never sent it, but I did. This is extremely frustrating and not efficient. I use Mail for my business email and all my personal emails as well, but mainly business.
I don't like Outlook for Mac (too slow), and I really don't like Mail for Mac either since my contacts and calendar are all in different apps.
Does anyone have a solution for the DRAFTS folder issues and/or can you recommend another e-mail client that is better. Outlook 2011 for Mac is just too slow, the beach ball is always showing when I try to use Outlook. And I really prefer not to have to go back to Windows Outlook through Parallels. I can manage with Mail.app if I could resolve this Drafts issue. I save emails all day long so to double check each one to see if I actually sent it is too time consuming.
I'm running on a Macbook Pro, 2.2 Ghz Intel Core i7, 8 GB memory.
Thanks in advance.
