Msync ask always password

Msync ask always password

Hi,
since few hours my Outlook client is asking me to edit the password (I do it correctly) but it always deny it. I suppose there's a problem with your Msync (msyn.zoho.com) coz my mails arrive on Zoho server.
And then, Zoho Mail ask me again yo solve the SPF record!!!!!

What's happening?
