Monitoring expiring keys - Outlook REST-API - no sufficient rights

Question

Hello,

a few days ago I had the issue, that our pipeline between Azure DevOps and Azure Portal was not able to deploy something because the secret keys of the registered service connection expired.

After fixing it I wanted to make sure that this does not happen again and found out that there is no native function built into Azure that sends out an alert in case a secret will expire soon. So I googled and found a Logic App that I can utilize to make this happen. Unfortunately I get this error message when utilizing the Outlook feature:

Check your account information and/or permissions and try again. Details: REST API is not supported for this mailbox. This error can occur for sandbox accounts (test) or for accounts that are on a dedicated (local) email server.

So now I am asking myself what exactly is missing here? Do my user in Active Directory needs permissions to utilize the Outlook REST API? Where do I set this up?

Thanks!
