We are going over the process to configure the first account in an Outlook for Mac, we will assume that you are using Office365 or Exchange On-premises and that the autodiscover is working properly with Public Certificates.
The process to install the Office for Mac was demonstrated in a previous Tutorial here at ITPROCentral.com, and after that when you open Outlook for the first time, the following wizard will show up. First select the option Make outlook the default applciation for e-mail, calendar and contacts and then click on Add Account
In the new window, click on Exchange or Office 365
Since we are using Autodiscover to configure this new account, we just need to provide the same information that we would provide in an Outlook for Desktop or even ActiveSync devices, which are e-mail address, username and password. Fill out all that information, make sure that Configure automatically is selected and click on Add account
The following dialog box my be presented, make sure to select Always use my response for this server and then click on Allow to get the automatic configuration working properly and stop receiving similar alerts as part of the autodiscover process.
That’s it, we can close the accounts window, and the e-mail will start synchronizing between your Office for Mac and Office365/Exchange On-premises.
