SMTP Error

[Tricey]

Hey i setup WHMCS and Configure my SMTP Server from Office365. I get Cronjob Mails but i dont can send Mails over WHMCS. Like Invoice or something.

I get this Error:  SMTP Error: data not accepted.

Here a Screen https://gyazo.com/c2ed7c414cb56a49785f26ae21ca2851

Hello @Tricey

A Data not accepted message is a rejection from the SMTP server that would warrant further investigation by your SysAdmin. Most commonly this happens when the sending "from" (SMTP user) address is not authorised.

You may consider following our troubleshooting steps in our Documentation that will output some additional debugging data: https://docs.whmcs.com/Email_Sending_Issues#Troubleshooting_2

Perhaps this will give you enough information on how to properly adjust the SMTP server to accept the mailings. The quickest method, however, is likely reviewing the SMTP logs to see why it is rejecting the connection.

@WHMCS SamP I contact the Microsoft Support and they sayed that is not a problem from Microsoft. They looked over my Settings in the Admin Panel from O365 and there looks all good.

I found the Problem it was a spelling misstake on my part
