Magento 2.4.8 / Office 365

[ShapesGraphicStudio]

Hello,
Just updated to 3.0.0 module now tries to send the mail.
But I'm facing a new issue with Office 365 config (working fine with Magento 2.4.7-p5 and SMTP module v2.9.2).

Test mail is returning following error:

Connection could not be established with host "ssl://smtp.office365.com:587": stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:1408F10B:SSL routines:ssl3_get_record:wrong version number

SSL Type is TLS
SMTP Host is smtp.office365.com
SMTP Port is 587

I'm also facing some admin page loading js issues as on some page loads the config fields are not showing up.. I have to hard refresh the page to make the input fields show up again. No issue when the module is disabled.

Some errors showing in console:
Uncaught TypeError: b.tagName is undefined
Uncaught TypeError: $(...).filter(...).collapse is not a function
Uncaught TypeError: ah.dispatchEvent is not a function

On hard refresh these errors occur no more and I can edit config.

Any ideas please?

switch to SSL type auth on port 465

I'm experiencing the same exact issue but on magento 2.4.8-p1 with the 3.0.1 module and a different host.
Here are my configurations:

SSL Type is TLS
SMTP Host is mail.ablia.net
SMTP Port is 587

just like op i get the following error message: "Connection could not be established with host "ssl://mail.ablia.net:587": stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:0A00010B:SSL routines::wrong version number"

Switching to SSL type on port 465 did not work either.
I have also applied the newest magento quality patch AC-14985 "Fixes the SMTP mail send with tls and 2.4.8." with no success.

Any ideas? thank you

We have this issue as well with mailtrap.io that uses starttls. I have created a PR to address our issues. My change should work with your providers if you change the SSL type to STARTTLS in the Magento admin config.

For more info see: #198

@danielkarso-pon awesome, it works now using STARTTLS thank you! May i ask when we can expect a new release that includes the fix?
