Connect to Microsoft365 Mailbox using Modern Authentication in C# .NET
Modern Authentication is now enabled by default for all new Microsoft 365/Azure tenants because this protocol is more secure than the deprecated Basic Authentication.
Modern Authentication is based on Active Directory Authentication Library and OAuth 2.0. It uses time-limited tokens, and applications don’t store user credentials.
In addition, it is planned to completely prohibit the use of Basic Authentication for all Microsoft 365 clients.
In this article, we will focus on using Modern Authentication to connect via EWS, SMTP, IMAP, POP clients of Aspose.
