how can I access the inbox of the one.com domain? I have tried using IMAP, POP3 protocols but got an authentication error in both
Have you tries these?
Yaa I have tried this link but for some reason I don’t know its not authenticating with IMAP activity. Credentials are also correct I have double checked them.
I think it’s best to write to one.com support team.
They might have a quick fix for you.
