I am using Mac Mail on my 2012 iMac running Mavericks.
In mail, I have set up two accounts: one is a Hosted Exchange account using rackspace.com and I have also set up an iCloud account. However when I look at the inbox for the two accounts, they hold different numbers of messages. My Exchange account shows more messages. The Apple iCloud account doesn't show messages past 7 am this morning. I am using the same email address for both accounts.
Also, when I try to compose a message using the iCloud account, it goes out OK but only comes into the inbox for the Exchange account, and does not show up at all in the iCloud account. Is there a problem having two accounts with the same email address?
Any help on these issues would be appreciated.
