Enter and Confirm my SRV record

Overview

Autodiscover is a protocol used to auto-configure email clients to connect to a hosted email account, with nothing more than the email address and password. It is primarily used with Microsoft Exchange mailboxes, but some email clients can take advantage of this feature for POP3/IMAP mailboxes as well.

Mailprotector publishes the XML data needed for Autodiscover features required by Microsoft Exchange ActiveSync and POP3/IMAP mailbox information. However, very few email clients support Autodiscover with POP3/IMAP accounts.

Autodiscover Options

Mailprotector's Exchange+ Mailboxes

Email accounts hosted on Mailprotector's Exchange+ 2013 or 2016 platforms will require an SRV record to be added to the domain's public DNS, also known as the nameserver. Connecting an email client to the hosted Exchange+ mailboxes is only supported through the addition of the SRV record method.

Email clients that support connecting to Exchange+ using Autodiscover are:

  • Microsoft Outlook 2013, 2016, and 2019
  • Microsoft Outlook for Office 365
  • Microsoft Outlook for Mac
  • Microsoft Outlook mobile apps (for Apple iOS and Android devices)
  • Apple Mac Mail
  • Native mobile device mail apps (Apple iOS Mail and Android Email)

Mailprotector's CloudMail Mailboxes

Mailprotector's CloudMail hosted accounts are POP3/IMAP mailboxes with 25 GB of storage. Email accounts hosted on the CloudMail platform may add an SRV record to the domain's public DNS to publish the XML file required for auto-configuration. However, support for Autodiscover with POP3/IMAP mailboxes is completely dependent on the email client.

WARNING: The following email clients do not support the Autodiscover feature with CloudMail:
Microsoft Outlook 2016, 2019
Microsoft Outlook for Office 365
Microsoft Outlook for Mac
Microsoft Outlook App for mobile devices
Mozilla Thunderbird
Any native mobile email clients (Apple iOS Mail, Android Email)

SRV Record Configuration

Mailprotector's Exchange+

To connect Microsoft Outlook and supported email clients to Exchange+ hosted mailboxes, you must configure the SRV record on the domain's public DNS, also known as the nameserver.

IMPORTANT: Microsoft has changed the default behavior of Autodiscover in Outlook to check for Microsoft Office 365 first. This behavior can cause connection failures or incomplete configurations. You may need to add Registry entries on Windows computers to skip Office 365 and root domain requests and ensure the Autodiscover request is made from the SRV record. Please see Outlook 2016 Not Connecting to Exchange+ Hosted Mailbox for complete details.

Configuration Requirements

Each nameserver administration panel will be a little different. Whether you use the domain registrar's (GoDaddy, Domain.com, Network Solutions, etc.) nameservers, a DNS host provider (Cloudflare, DNSMadeEasy, etc.), or web host provider (Bluehost, Hostgator, WPEngine, etc.), the SRV record will need to contain the required information for the Autodiscover request to function as expected.

If you are not sure how to add or configure the DNS records on your domain's DNS nameserver, please contact the support of the hosting provider managing the domain's nameserver.

  1. BEST PRACTICE: Remove any Wildcard or CNAME records from the domain that may conflict with the Autodiscover process. Conflicts with these types of records can cause certificate warnings or inaccurate email client configuration.
  2. Add an SRV Record to your domain's DNS using the information below:
    Exchange+ 2013 Platform
    Service _autodiscover
    Protocol _tcp
    Port Number 443
    Host exchange.mailprotector.com
    Priority 0
    Weight 0

    Exchange+ 2016 Platform
    Service _autodiscover
    Protocol _tcp
    Port Number 443
    Host exchange.emailservice.io
    Priority 0
    Weight 0
  3. NOTE: DNS changes need time to propagate/update across the internet before the SRV record reflects the change in the Mailprotector Console or manual DNS queries. Please expect to wait between 15 minutes and 24 hours before the changes are visible.

    Test the SRV record change by checking the Overiew page of the domain in the Mailprotector Console, or perform a manual DNS query of the SRV record. (i.e. - QueryDNS)

Once you've entered and confirmed your SRV record, click here to setup Outlook to connect to your Hosted Exchange. Manually connecting an Outlook client to Microsoft Exchange is not supported. Full features, such as Out of Office replies and Public Folders, only work when successfully connected to the mailbox via Autodiscover.

Mailprotector's CloudMail

In most cases, connecting an email client to CloudMail via POP3 or IMAP requires manual configuration because the Autodiscover process is entirely dependent on the email client. Very few email clients support Autodiscover for POP3/IMAP configuration.

However, Mailprotector does publish the necessary POP3 and IMAP XML data for CloudMail accounts to be used with Autodiscover.

  1. Add an SRV Record to your domain's DNS using the information below:
    CloudMail POP3/IMAP Mailbox
    Service _autodiscover
    Protocol _tcp
    Port Number 443
    Host autodiscover.emailservice.io
    Priority 0
    Weight 0
