5. Error and Solution

At the time of login with outlook,may be facing this error:
Error: https://graph.microsoft.com/v1.0/me API is not provide mail address

The following steps need to be taken to resolve this error:
- It's been set on on-premises AD, and then synchronized to Azure AD using AD Connect
- The cloud user has been assigned an Office 365 license (and a mailbox), at which point the mail property is set for this licensed user.
- It means the user does not have the mail property. The mail is read-only which is the SMTP address for the user. It is tied to Exchange Online, you could not write to that attribute unless you have an Exchange Online license, when you activate a license for the user, Exchange Online will update the field with the correct mailbox mail address during the creation of the user's mailbox.
