[neomutt-users] Can't get IMAP running exchange 2016

[Lars Quentin]

Good evening,

I think I figured out the problem but I don't know how to fix it.

After reading the "RFC 4616.2. PLAIN SASL Mechanism", I saw that the 
plain login in neomutt is tried as

ug-student\lars.quentin\0ug-student\lars.quentin\0my_secure_password

which doesn't work when I try it myself via openssl as well.

But when I decode it as

\0ug-student\lars.quentin\0my_secure_password

as told here (https://stackoverflow.com/a/14158574), it works.

How do I properly configure it that it leaves the first parameter empty? 
Or am I missing the whole point?

Cheers
Lars
