更新が滞っているのは色々ご都合があるものと思います。

提案ですが、開発終了するならばオープンソースにするのはどうでしょうか。Wordpress関数などにはまだあまり知識はないですが、当方でも可能な修正箇所もあります。他の方でもできることはあるでしょう。GitHubなどにリポジトリを上げて有志で開発継続するのも手だと思います。

@crohammer Hi, do you mean when you use Office 365 mail integration plugin, you can’t use a shared mailbox for sending emails with WP system email, is it right? If so, I think it is caused by misconfiguration. In my circumstance, WP could send some emails, as cited above.

I don’t know WP mail SMTP (plugin?) but does it work with MS 365 mail server,
not with a shared mailbox? I recently found somewhere on internet, possibly MSDN, that MS changed the email authentication protocol for a much secure one. Now users can’t use Thunderbird or Gmail for sending and receiving 365 mail. The bundled mailer of iOS can treat 365 mail. But it is an exceptional case.

I’ve met the same problem. Curiously, I can’t receive new order emails but I can receive the confirmation mails when manually added orders are finished. Now I use Mailgun plugin temporally but want to use 365 mail. Is it related to using a shared mailbox?

Additional Information: the mails sent by Mailgun can’t reach a shared mailbox of Microsoft 365.

I found the resolution. I used Chrome, but it works fine with Firefox. I don’t know why. Developers will find the solution.
