Hello Elistone,
the problem seems to be with Authentication to the server. Have you changed your login credentials? Can you login into this mail account through webmail?

Regards,
Olivia

I didnt change any login credentials but the problem seems to have fixed itself that day, as it has been working fine since that day. maybe it was a problem on hotmails end?
