Symptoms

  1. Office 365 for Mac, Outlook unread count wrong I recently received a new MacBook Pro and restored all of my previous applications and data from a Time Travel backup. One small issue that I noticed afterwards was that the Unread mail count (1) was incorrect, since even when I set a Filter to show only unread items there were no remaining mails.
  2. Outlook 2016 clients (internal and external) not able to create new connections to Exchange via AutoDiscover. It fails to even locate the Server settings Mobile Users have no problems creating Mailbox connections to Exchange.

When Microsoft Outlook 2016 for Mac connects to a Microsoft 365 account, Autodiscover is redirected from HTTP to HTTPS, and you may receive a warning message that resembles the following:

Outlook was redirected to the server Autodiscover-s.outlook.com to get new settings for your account user@domain.com. Do you want to allow this server to configure your settings?
https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml
Click Allow only if you fully trust the source, or if your Exchange administrator instructs you to.

When this warning message occurs, you may select Always use my response for this server and then select Allow in order not to be asked about this specific server again for this Outlook 2016 for Mac profile.

You or administrators may want to suppress the initial warning message. This article contains information about how to do this.
