If you experience the below warning message when selecting the calendar tile within MyDay then read through this article.

Error:

Symptom: No O365 events coming through but i can see events on outlook.com.

Explainsation: “email failed to retrieve data” means that there’s no data for myday to pull and push through to your calendar.

Checklist:

Ensure Oauth is checked as this would need be turned to be using modern authentication which is how myday Calendar/Mail app works.

To find this you will need to go to Control Panel > Connectors > Exchange > Edit > Tick Use OAuth Authentication for Office 365.

Steps to resolve:

ONLY TO BE ACTIONED IF ALL STUDENTS ARE AFFECTED

One way to resolve this issue is by re-consenting on the myday office 365 app itself on Azure.

  • Look for the myday O365 apps in Enterprise apps and click on it.

  • Go to permissions and grant consent. This will reset the tokens for all users

Access Permissions - Check if the account receiving the error has a shared mailbox with multiple users. Best to check calendar permission and remove the duplicate user entry.
