credentials

Hi ​@Jarek 

I’m not sure what you are actually looking for here, are you looking to see what mailboxes are being protected or something else?

no, I'm looking for information about what user is connected to the 365 tenant from Exchange Online Apps in metalic, I didn't write it and I want to connect additional services such as Teams, One Drive etc.

Good Day ​@Jarek,

I guess your question is mostly on the User Account used to authorize the Azure Application, if that’s the ask - you can navigate to Configuration tab of the O365 App and then under Connection Settings you should be able to see the column “Authorized by” field (just for Teams), but other’s you have to get the Application ID and check on the Activity logs on Azure portal which will help with details on which account is used for Authorization each time of the API call happening, but mostly likely on Azure you will find only Service Principle sign-ins which is mostly token based login’s.

Reference applicable only for Teams from SaaS Console: 

Hope this helps with the information, do let me know if any questions or concerns.
