I have a client whose mailbox is hosted with GoDaddy (Via Office365).
When i setup the account in Outlook 2016 it accepts the password the first time but then asks for it again and again as soon as you close Outlook and it wont accept the correct password. There are no security options to configure in advanced settings , its all greyed out. I dread having to contact Go Daddy as i am not the account holder , this is being managed by another IT consultant whose hard to reach.
Any suggestions would be great
