--- Comment #18 from Olivier <olivier.dug...@orange.com> --- Hello Martin I recently upgrade to latest Neon packages: 18.12.2, so kdepim 5.10.2, and performed a new test. Unfortunately, it is always the same. Only kerberos authentication works. I always got the same error 401 in the console when attempting to login with my login/password. Perhaps it is due to our version of Exchange Server. -- You are receiving this mail because: You are watching all bug changes.
