Re: Office 365 smtp setup

Hello GoDaddy has two email servers. One is Office 365, which is fully supported by GoDaddy. The other is legacy IMAP, which GoDaddy is no longer investing in.


Office 365 IMAP Setting

  • Incoming Server:
  • Port: 993
  • Connection Security: SSL/TLS
  • Authentication: Password
  • Outgoing Server:
  • Port: 587
  • Connection Security: STARTTLS 
  • Authentication: Password

I hope this will resolve your issue.

Hello @Zulfiqar,

I was able to solve it. I was using TLS for Connection Security instead of STARTTLS .

Thanks for your help.
