When you have installed the new Exchange Server 2016 at you Windows Server and want to configure the Exchange account in the Outlook, then there is a useful feature called Autodiscover. The Autodiscover feature facilitates the user to only input the user ID, and password and the account gets configured automatically. The Autodiscover finds the EWS (Exchange Web Services) endpoint in the URL for the clients. The automatic configuration using the autodiscover is possible as:

1. Exchange creates a new virtual directory (autodiscover) in the default web site under IIS.
2. The Active Directory provides and stores the URLs of computers in the domain.
3. The Client Access Service on Mailbox Server performs authentication and provides proxy services for the client connections both internal as well as external.
4. Outlook takes care of configuration using the username and password only.

But if the autodiscover is not active, then the account will not be set, and you will have to face the following error –

OR

Your account was redirected to this website for settings. You should only allow settings from sources you know and trust.

Cause of the error

The cause behind the error is the IIS Services is not active by default in server manager. The autodiscover feature is the sub-service of IIS Server, and it will be activated only when the IIS Server is in the activated state.

You can check some point to make sure the error is not occurring due to them:

1. Check all the Exchange Service are working perfectly well.
2. In the IIS Manager, all the Application Pools are in ‘Started’ status and the .Net framework is greater than 4.0.
3. Go to Sites, select the Default Web Site and right-click it. Here check that the SSL Certificate is correct (443 or 444).

Solution.

The Autodiscover service will only work when the IIS Services is active. So, you need to start the IIS for it. Follow the below procedure –

1. In the Exchange Server 2016, open the Server Manager and then select Local Server. Now select Manage ≫ Add Roles and Features.
   
2. The ‘Add Roles and Features’ wizard will open. It will brief you about the installation of roles, role services, and features. Click Next.
   
3. Select the first option of ‘Role-based or feature-based installation.’ Then click Next.
   
4. Select your server from the Server pool and click Next.
   
5. Under the Server Roles option, select Web Server (IIS) and select it; click Next.
   
6. The final confirmation option will brief you about your selection. Click the Install button.
   
7. The pop-up window will ask your permission to start the installation. Click Install and the tools will start to install.
8. When the tools have installed, you can go to IIS Server in the Server Manager and check if these tools are present in the list.
   
9. Now, restart the IIS Server, and the autodiscover feature should work properly, and there will be no error anymore

If the account is still not configuring automatically, then the problem may be different, and you need to run other diagnostics tool to check corruption in the database. You can go for using the ESEUTIL tool to repair the database. But the ESEUTIL tool can further damage the situation by deleting the corrupted data and creating the blank spaces. That’s why you should use a trustworthy professional Exchange Server recovery tool which can remove the corruption and recover the complete data.
