How to troubleshoot an issue in which the Mail app cannot connect to the Exchange server
If the Mail app cannot connect to the Exchange server, you receive the following error message:
Unable to connect. Ensure the information entered is correct
Email address is unavailable
This issue may occur because the Mail app cannot connect to the Exchange server by using self-signed certificates. Contact your system administrator to resolve this issue.
A system administrator can use one of the following methods to resolve this issue.
Method 1: Install a certificate on the server that is signed by a Microsoft-trusted root certification authority (CA)
This enables the Exchange server to work for all clients without prompting. For more information about trusted root CAs, go to the following Microsoft TechNet websites:
Method 2: Install a self-signed certificate or an untrusted root CA certificate on a device
This enables the Exchange server to work for Windows 8 devices that have the certificate installed. Note
To install a self-signed certificate for a domain’s CA, the administrator must provide a certificate file (.cer). The certificate can be installed into the trusted root CA store for either of the following:
- For the current user - This option does not require administrator rights, but must be completed for each user on the device.
- For the local device - This option requires administrator rights, and has to be completed only one time for a device.
The user or the system administrator can use the .cer file to install the certificate. If you are a user and you need assistance about how to do this, contact your system administrator.
To install the certificate, use one of the following methods:
- Command-line tool
Note This command installs the certificate for all users on the device.
- Open an elevated command prompt. To do this, follow these steps:
- Swipe in from the right edge of the screen, and then tap Search.
Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search.
- In the search box, type command prompt.
- Swipe across or right-click the displayed Command Prompt icon.
- Tap or click Run as administrator.
- Run the following command at the elevated command prompt:
certutil.exe -f -addstore root <name_of_certificatefile>.cer
- User interface
- Double-click the certificate file. A certificate dialog box appears.
- Click Install Certificate. A Certificate Import Wizard window opens.
- Select the option to install the certificate for either the current user or for the local device.
- Select Place all certificates in the following store.
- Click the Browse button to open the store selection dialog box.
- Select Trusted Root Certification Authorities.
- Select the store, and then click Ok. You are returned to Certificate Import Wizard dialog box, and both the certificate store and the certificate to be installed into that store are displayed.
