Hi, we have recently migrated our old Exchange 2007 to Office 365, and everything have been going great,but one thing. i cant seem to get the DNS records right whit our provider.
I want mail.mycompany.com to redirect to the Office 365 login page. But i run into different issues every time.
i have found articles from 12, 13, 15 and all of them have different URL's to use.
I set up a CNAME record at my DNS provider using mail.mycompany.com to redirect to a O365 URL but nothing seems to work quite right i have tried:
outlook.office365.com (this works 50/50 and is giving me certificate issues)
outlook.office.com (again its 50/50, but mostly i get this error "Error
AADSTS70001: Application with identifier https://mail.mycompany.com.orgid.com was not found in the orgId tenant."
mail.office365.com this have all of the issues described above.
Any...
