How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A declining trend compresses what a buyer would pay.

   We switched to Microsoft 365, so it made sense to use that setup to send emails from our website (from an authenticated email, not spam perspective). This plug in guides you through the process of getting Microsoft 365 to work with your WordPress website. Follow the instructions carefully, it’s one of those “don’t do this if you’re sleepy” processes — especially if you’re not familiar or expert level with Exchange admin (or maybe that was just me 🤔) Recommended!

   I’m loving this plugin! I manage a lot of WordPress websites for clients who use Microsoft 365, and working out how to send emails properly from WordPress has been such a frustration lately. WPO365 Graph Mailer has made the process so much easier. Setup was straightforward, and once it’s configured, it just works. Using Microsoft Graph instead of SMTP feels much more reliable, and I’ve had great success using it across multiple client sites. I also had a question during setup and got a very fast response from the author, which was hugely appreciated. Great support makes such a difference. This plugin has saved me a lot of headaches — highly recommended for anyone managing WordPress sites with Microsoft 365 email.

   My problems with Microsoft 365-Account sending were solved by the plugin in a minute. Ok, you have to go trough that Microsoft Azure registration routine, but then it rocked! Other plugins didnt do that! I am very happy! Thank you. Vera

   It works as expected and is currently a strong option for enabling the Microsoft Graph API without a monthly subscription. The setup steps for connecting your Microsoft SMTP account are well documented.

   This is a very good plugin, and while a little more complex to setup works very well. It is about the only Office365 compatible SMTP plugin I could find without an expensive Pro Subscription. I had nothing but problems with FluentSMTP and WP Mail SMTP is too expensive. So I am glad I found this plugin. At some point we’ll upgrade to pro to support the author.

   Perfect. Now I don’t have to worry about this for another 2 years when the password expires 😂 I have created a calendar entry but I wonder if Microsoft will send an email before expiration 🤔 Anyway, thanks a lot! This topic was modified 8 months ago by Jmarc.
