To connect Microsoft accounts to Instantly, it is essential to enable SMTP.
When you get Microsoft 365 accounts on GoDaddy, the setup is different than for the accounts bought directly from Microsoft. You won't be able to access all the features in Microsoft Admin, instead, your SMTP email settings will be on GoDaddy.
To connect your accounts to Instantly, you need to have SMTP enabled.
Simply access your Email Dashboard on GoDaddy, Scroll down to Account information and select Advanced Settings.
Enable SMTP for your accounts by turning on the toggle:
Select Continue and confirm the changes made.
Next thing is to add the DKIM and DMARC records to your domain.
Step 1. You will be able to generate DKIM via this link: https://security.microsoft.com/dkimv2
Click on the domain you want to generate the records for.
Step 2. In the pop-up window click on "Create DKIM keys"
Step 3. You will need to copy these CNAME-type records into your Godaddy domain and come back to the same page to enable DKIM.
Step 4: Publish both of the copied CNAME records to your GoDaddy DNS.
Step 5. Go back to the Microsoft page and click the switch to "Enable".
Now that you have DKIM enabled, you can proceed to the last important action - creating DMARC.
v=DMARC1;p=none;sp=none;pct=100;rua=mailto:[email protected];ruf=mailto:[email protected];ri=86400;aspf=s;adkim=s;fo=1
*For rua and ruf tags in the Value field, replace [email protected] with your email address.
TTL for this record is set to the lowest possible (1h is perfectly fine).
Click to "Add record" and you are done!
You can verify if your records are in place with tools like MXToolbox.
