Cannot sync Outlook 2013 to Exchange Online Account. Autodiscover not working.


  • Hello,

    I have setup a mailbox on Exchange Online.  I can send and recieve mail from the Office 365 Outlook Web App and I succesfully connected my Outlook 2013 via IMaP  and uploaded my old email to the account but new email that lands in the account (Outlook 365) does not sync to Outlook 2013. However, on my computer, email sent from the Outlook 2013 does go out and is recieved by recipients.

    Also, Auto Discover does not work.  I have the cname on my account set up with for  but it is not found after downloading Set up and configure your Office desktop apps from the "Resources" and requires "manuel" setup.

    In the manuel setup it is not clear to me where/which server I use if I try to setup with the or Exchange ActiveSync compatible service. 

    Thank you for any help.  Mark
