Error on SMTP, random problems with authentication

Question

So for the buisiness I work for we use SMTP Office 365 to send the emails from our webshop to our customer.

Lately we are getting a lot of random errors on the authentication.

e.g.

> Could not read from smtp.office365.com {"exception":"[object] (Magento\Framework\Exception\MailException(code: 0): Could not read from smtp.office365.com at /home/sicomputers/www/vendor/mageplaza/module-smtp/Mail/Transport.php:141, Laminas\Mail\Protocol\Exception\RuntimeException(code: 0): Could not read from smtp.office365.com at /home/sicomputers/www/vendor/laminas/laminas-mail/src/Protocol/AbstractProtocol.php:309)"}

This is very annoying and I like to get it resolved asap.

Who can help me?

Daniel
