Hey everyone! I'm looking for advice on the upcoming SMTP Basic shutdown that's set for September. My GLPI is currently set up for internal access only and uses SMTP Basic for sending email notifications. I'm curious about what solutions you've explored regarding this change. I've heard about using OAuth authentication—could this be a good alternative? Thanks to anyone who can share their thoughts!

We opted for Postfix on-prem and connected it to our MS365 tenant using Exchange Connectors. This was particularly useful for sending via shared mailboxes and handling high volume outbound emails. It might be worth considering.
One solid option is to use SMTP2GO; it’s reliable and pretty budget-friendly. But if you’re just running emails internally, there are some alternatives you might want to check out too. For instance, Microsoft has a high volume email feature that’s currently in public preview, but it's important to note that pricing is still under wraps once it leaves that phase.
If GLPI can’t use Graph API for sending emails, you might need to look into a local relay that supports certificate authentication for Office 365. Setting up SPF, DKIM, and other authentication methods can also help in sending emails directly from your IP without requiring passwords.
We’ve set up an intermediate on-premise SMTP server that works with OAuth via Microsoft. It allows our devices and application servers to send emails smoothly. The SMTP server we’re using is Xeams.
We're running Exchange 2019 as an SMTP relay server for our internal services, and then we route all emails through our hybrid Exchange Online tenant. This setup has been working well for us.
