Setting up Oauth IMAP Entra

TLS Protocol

Microsoft is gradually removing the TLS 1.0 and 1.1 protocols for all Microsoft 365 applications. In order to keep your collector running, you need to add an Oauth IMAP plugin available in the marketplace.

OAuth IMAP and MFA

The Oauth tokens for the collector, retrieved during authentication with Azure by the OauthIMAP plugin, are "offline" tokens that delegate authorisation to a third-party application (GLPI). These tokens provide a renewal code that will be used by the application to renew them automatically without user intervention. You will therefore not be asked to re-authenticate after the 1st authorisation request (unless you change your password at a later date).

Requirements (on-premise)

GLPI Version	Minimum PHP	Recommanded
10.0.x	8.1	8.2

Here are the configuration steps including configuration phases on the Azure side.
