Failed IMAP Migration on Office365
I am having the following error while establishing a IMAP Migration Job from MDaemon to Office365
Error: TooManyTransientFailureRetriesPermanentException: The job encountered too many transient failures (61) and is quitting. The most common failure is ImapNoResponseException with the hit count 60. --> Imap server sent NO response to SELECT. Response code: '', message: 'Access denied'.
I have tried just 1 user at the moment and getting the error.
Thanks.
