So you have just begun the Office 365 pilot and notice that despite you only migrated a couple of on-prem Exchange mailboxes to Office 365, that users are complaining about a warning they receive in Outlook looking similar to:
Allow this website to configure [email protected] server settings?
https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml
Your account was redirected to this website for settings.
You should only allow settings from sources you know and trust.
So this usually happens when an on-prem user have been delegated access to a mailbox that have been moved to Office 365. This is because Outlook will do a new autodiscover request to determine the location of the mailboxafter it has been moved. This is based on the targetAddress set for the user mailbox or mail user object.
Until the respective user have had his mailbox moved to Office 365, you can use the following workarounds to get rid of the Outlook warning:
- If dealing with managed machines, follow http://support.microsoft.com/kb/2480582 to suppress the Outlook warning
- Inform the user to select “Don’t ask me about this website again”
Until later,

So, is it safe or not?
Hi MSExchange team.. I have exact same scenario and same problem but only problem is, that this issue is on MAC.
So where do I go in MAC to avoid getting this error, and what are the changes to be done.
This message is popping up regularly asking
“Allow this website to configure ..” – then one of my employers´ email address. Not just one name but email-addresses of two different bosses in my organization. Could this be a sign, that they are peeping in on my account?
