Hey @tmueller,

i don’t know much about Exchange but “real” SSL POP3 should probably be on port 995.

Depends if you use SSL/STARTTLS.

cheers


#7

ok i am working on that

but if i use pop3 without encryption this error appears:


#8

Is Port 110 your unencrypted Port or the SSL port?
Sorry, but helping you is impossible with that information set.


#9

110 is Exchange 2016 POP with STARTTLS

so it should be work with port 110 an ssl/starttls set to yes

but if set it to that port using pop3
