Sending mail with SMTP without UTF8 functionality


We are trying to send mails with Power BI Report Server (subscriptions) but we have the following error:


This is the mail system at host ........................................

I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can delete your own text from the attached returned message.

The mail system

<>: SMTPUTF8 is required, but was not offered by host ...........................


In the official documentation the UTF8 functionality is mandatory.


My question is if any of you have found a workaround on the Power BI side?


Thank you in advance for your feedback,


Beautiful day,

Good morning,


UTF8 is mandatory only for attachments. However there must be something to be enabled on the SMTP server.


Do you have any information about this?


Thank you in advance for your feedback,


Beautiful day,
