Send Mail return authentication error

[Angela_Wolter]

Hi,

I have used your application automation to create + distribute an excel file; however receive an error at the send mail block returning an authentication error. I have MFA enabled for my office 365 account, as a workaround tried to generate an app password as additional authentication method and copied this password into the mail block, but with the same error being returned.

What am I missing?

thanks and best regards

Angela

Ensure that you have given correct Port and Security.

smtp server = smtp.office365.com, port 587 starttls - correct?

best regards Angela

Thats correct setting for Office 365

Hello @Angela_Wolter ,

yes, that is correct:

Device or Application setting	Value
Server/smart host	smtp.office365.com
Port	Port 587 (recommended) or port 25
TLS/StartTLS	Enabled

Hi 

Im facing the same issue, and have pretty much tried and taken the same approach @Angela_Wolter did with creating app password and once failed attempted  @Rakesh_HB  has recommended but still having issues connecting. Is there a particular Version of TLS/StartTLS we should be enabling 

Following are the settings
