Hello

 

My company is currently evaluating FreshDesk and we have setup 
M365 as our inbound and outbound email 

When a user sends an email to support@node-red.tech the ticket is received correctly in FreshDesk but when a replay email is sent from FreshDesk we are getting the below error

 

Delivery has failed to these recipients or groups:

postmaster@outlook.com
Your message wasn't delivered because the recipient's email provider rejected it.

Hi

Which email management software are you using? Our company uses Mimecast, and you will have to greylist those emails so that they do not get picked up as Spoofing. We actually bypassed this issue by using user accounts with a Microsoft license instead of a standard shared mailbox.

Hello @Node-Red,

Thank you for asking your question; I’ve just gone ahead and moved this conversation over to our Freshdesk board, so it’s under the right category. Cheers!
