Hi Professionals,
At any time when I open the iCloud calendar I am getting this message. The username and password is already configured but still why I am getting this error. Why it is not recognizing my username and password? This is really making me tired and I lost some of my data. Professional help is always great. Help please.
Error:
Authentication Required
The server http://p13-calendatws.icloud.com:443 requires a username and password. The server says: MMCalDav.
