Basic authentication for external mail sources replaced with OAuth 2.0

Microsoft Exchange Online and Google Mail will drop support for basic authentication (username/password) in the near future. This means that, after this, M-Files will also need to drop support for IMAP4 and POP3 basic authentication from our mail sources when connecting to Microsoft Exchange Online or Google Mail.

Microsoft Exchange Online

Support for basic authentication will end in the near future for all Exchange Online accounts. Exchange On‑Premises accounts are not affected.

We are targeting to release OAuth 2.0 authentication support for the external mail sources feature well before the basic authentication support ends for Exchange Online accounts.

Google Mail

Support for basic authentication will end for all G Suite accounts in the near future.

External mail sources continue to support basic authentication with the IMAP4 and POP3 protocols when connecting to mail servers other than Microsoft Exchange Online and Google Mail.
