Hi Ashok,
- No, this is happening on brand new devices that are Azure AD joined
- No, this is happening when logging in for the first time on a new device.it is affecting multiple users though I'm not 100% if everyone
- The users login with the email/O365 account e.g. olly@Work .com
- Yes it's what Outlook defaults to when you create a new email profile. The main issue is that Outlook is unable to auto-login with the linked Windows 10 work/school account and
silent login is failing. You have to manually delete the domain prefix and enter the password, at which point it logs in and sets up the Outlook account perfectly fine. - We've had this problem since the domain was unlinked from O365, for several years. It's always been a minor annoyance but we're now trying to do more with Intune and device
auto-provisioning and it's becoming a real pain. I believe all the steps were followed for unlinking the domain from O365 but maybe something was missed?
Thanks
