can't send mail using exchange account in mavericks
Since upgrading to Mavericks I have had multiple problems sending mail. When I use my exchange account for work many emails will not send. This seems to happen more oftern when I have attachments, even reasonably sized attachments. The connection doctor shows a good connection to the exchange server. The messages just won't go out. I do not see any options in the settings for the exchange account that I can modify to fix this problem.
