Autodiscover exposed
for Exchange & O365 Autodiscover is a fundamental technology in Exchange and Office 365. When Outlook first starts the ‘out of the box experience’ is that it will first of all figure out if it can find an email address for you on the account you’re logged in with and then takes you through a […]
