Outlook Hosted Exchange Logon Icon keeps popping up

ISSUE : Outlook Hosted Exchange Logon Icon keeps popping up Found Outlook 2010 Logon popping up. Hosted Exchange e-mail with Rackspace Support was not much helpful, told me to delete the local Credentials from the Credential manager. Deleted everything Outlook, still No Go. FIX: Found out the domain DNS records were all not right. Especially the autodiscover Fix/Add autodiscover and the SPF Text record on your Public DNS server for your domain. Wait about a day And all will be fine
