Hello friend ,

While sending mail through 360 works its giving an error Authentication failed, please check authentication information. While my authentication information is almost very true.

Hello,

Are you hard coding your credentials into the function call or using a field reference? Often when I have users report this issue, it is when they are using a field reference and the script is in the wrong context so the fields being referenced aren't the ones with the correct authentication info. I would recommend that you trying hard coding your authentication information into the EmailConnectSMTP function and seeing if the error persists. If it does, we will need to see your plugin logs to troubleshoot further. Make sure to reproduce the issue and then send the logs. You can send them to [email protected]. See this page for log locations.
