Setting up Autodiscover
To ensure that Autodiscover functions correctly, please follow these instructions to configure your DNS settings:
Step 1: Remove Existing Wildcard DNS Entry
Ensure that the subdomain autodiscover is not being resolved by a wildcard DNS entry.
Step 2: Configure the SRV Record
Instead of using an A record for the subdomain autodiscover configure the following SRV record on the subdomain _autodiscover._tcp in your DNS server:
- Service: _autodiscover._tcp.example.com
- Port: 443
- Server: mail.example.com
Example SRV Record Entry
| Field | Value |
|---|---|
| Service | _autodiscover |
| Protocol | _tcp |
| Name | example.com |
| Port | 443 |
| Target | mail.example.com |
Step 3: Verify the Configuration
After making these changes, you can verify the functionality of Autodiscover using the following Microsoft services:
