Thanks all. This is quite maddening. Mavericks Mail was so bad for me that I decided to switch to Outlook 2011, which is free from my Exchange provider. I wanted to share two specific problem areas.
1. I had no trouble with the basic setup/synching. Yet I could not move to Outlook the archived emails I store locally. Mail's mbox format has changed in a way that makes it unreadable by Outlook. I have seen lots of comments about this, and refrences to third party solutions, but none worked for me. Almost everywhere I look, FAQs do not recognize that exportingin mbox will no longer work as it once did.
2. My "workaround" was to put these locally stored emails (which are organized into folders) back onto the Exchange server, in the hopes I could synch in Oultook and then move off the server and store locally within Outlook. Even though I bought lots of additional storage on the Exchange server and moved a few file folders at a time, I found that some files were dropped and some subfolders never synched. I do not think it makes sense of me to do this one email at a time as I would have to keep track of thousands and confirm every one moved.
I am losing my hair as it is, and this is causing much more pain than it should. Apple does not support Outlook so they point me to MS. MS points to Exchange. Exchange points to Apple and MS. A circular firing squad.
Anyone have a suggestion?
thx
