Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
Do you have the same email account connected to any other device or computer?
To start with, I need to know the version of mac osx you have on your machine, you can check as follows.Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, would you like me to connect to your computer from here and work on the issue directly on screen? If so we can set this up via a secure remote assistance session. That session is guaranteed meaning if I cant help you then you will be entitled to a full refund of all fees.Otherwise, I can try and assist you via written support alone. Let me know how you'd like to begin.
Im here.. It takes time to receive your reply, read it, and then formulate & write my reply to you in turn. You did ask for written support yes?
If so, please be patient.. As written support is by its very nature, slower. And each time you send a new reply I have to stop typing, read what you had to say, and then switch back over to continue typing.
With that being said.. When you added the exchange account, did you add it using auto discovery in mac mail. Or did you manually set up the exchange account?
