If you're having trouble signing up or logging in with Office 365, there could be several reasons.
Your organisation does not allow software to access their information without prior approval.
- To solve this issue, you'll need to get permission from your organisation admin.You don't have Integrated Apps enabled on the Office 365 platform.
