Hi,

I'm using a Office 365 account in our phone system to access all users Exchange calendar, but after Microsoft Security Defaults have been enabled, it's no longer working. I'm getting this message:

the OIP cannot successfully connect to the Exchange Server.

This may have the following reasons:
- Incorrect User or password
- Domain name cannot be determined, or is incorrectly specified.
- The user has no impersonation rights   --> see on the online help OIP
- Basic authentication in Exchange Online was not activated   -->

I've reset the password and can login to the office portal with the account. I've tried creating a app password and use this, but with no luck. How can I enable basic authentication for just this one account in Office 365?

Thanks,
Ronnie
