An encrypted connection to your mail services is not available

When you test by using the Microsoft Remote Connectivity Analyzer, the following error message may be returned:

Note

If this method doesn’t resolve the problem, go to Method 3.

Method 3: Make sure that the Autodiscover CNAME record is set up correctly

The Autodiscover CNAME record must exist and must be set up correctly. We strongly recommend that you set up Exchange Autodiscover when you are using Outlook to connect to Exchange Online mailboxes. Setting up Autodiscover and other related DNS records is required for Outlook connectivity in Exchange Online. Administrators can use the Domain Troubleshooting Wizard in Office 365 or Microsoft Remote Connectivity Analyzer to confirm that the records are set up correctly.

Use the Domain Troubleshooting Wizard in Office 365

To use the Domain Troubleshooting Wizard in Office 365, follow these steps.

1. Sign in to the Office 365 portal (https://portal.office.com) by using an administrator account.
2. Click Admin to open the Microsoft 365 admin center.
3. In the left navigation pane, click Domains, select the domain name that's used by the affected user, and then click Troubleshoot to start the wizard.

Use Microsoft Remote Connectivity Analyzer

To use Remote Connectivity Analyzer to test whether Exchange Autodiscover is working correctly, follow these steps:

1. In a web browser, browse to the Microsoft Remote Connectivity Analyzer tool at the following website:

2. Complete all the required fields on the form, and then click Perform Test.

3. When the test is finished, determine whether it's successful.

   • If the test is successful, Autodiscover is working correctly.

   • If the test fails, verify that the Autodiscover service is set up correctly. For more information, see the following resources:

     • If all mailboxes in your organization are in Exchange Online, add an Autodiscover CNAME record. For more information, see Create DNS records for Office 365 at any DNS hosting provider and External Domain Name System records for Office 365.
     • If you have an Exchange hybrid deployment, set up the Autodiscover public DNS records for your existing SMTP domains to point to an on-premises Exchange server. For more information, see Hybrid deployment prerequisites.

Method 4: Make sure that the user's attributes in Active Directory are set correctly

You can use the Get-RemoteMailbox cmdlet to determine the whether the following attributes are set correctly for the user. Common issues occur when a value is not set for one or more of these attributes. The following is an example of the correct attributes.

Attribute	Example
primarySMTPAddress	ted@contoso.com
alias	ted
displayName	Ted Bremer
emailAddresses	SMTP: ted@contoso.com X400:c=us;a= ;p=First Organization;o=Exchange;s=Bremer;g=Ted
remoteRoutingAddress	ted@contoso.mail.onmicrosoft.com

To update these attributes, you can use the Set-RemoteMailbox cmdlet.

After the correct values are set for these attributes, force directory synchronization to occur, and then try to set up the user's email account in Outlook.

If you're not using a custom domain

Method 2: Use the Add New Account Wizard in Outlook

If Method 1 doesn't resolve the problem, and you’re not using a custom domain together with Office 365, you can use the Add New Account Wizard in Outlook to set up your Outlook profile by using the default 'onmicrosoft.com'-based email address that’s associated with users’ Exchange Online mailboxes when you signed up for Office 365. When you use the Add New Account Wizard to set up a new mail profile, you specify your Office 365 password and your default Office 365 email address in the form of <user>@<domain>.onmicrosoft.com (for example, kim@contoso.onmicrosoft.com).

This method is supported and works for customers who may not plan to have their own vanity or custom domain. This method also supports Autodiscover. If your mailbox server location changes, Outlook is updated accordingly by using the new location of your mailbox server.

More information

Microsoft doesn't support manually setting up a profile in Outlook for connectivity to mailboxes in Exchange Online in Office 365. However, we can help you complete other tasks, such as setting up DNS and Autodiscover records (as discussed in Method 2). This lets you set up your account through the supported methods.
