Hi 

Can someone tell me difference between logs received from Azure AD and office 365 azure AD logs , 

So if there is a login failure to an outlook or any other o365 app, will that event be seen in both Azure AD and office 365 azure AD logs?

What I've observed when working on users who are in the Entra ID environment that have O365 accounts, you have the ability to get Azure Sign-In events and O365 login events that both will cover successful and failed logins. If you are doing non-interactive sign-in logs, ie refresh tokens, you would see that in Azure Activity data.

If we draw a venn diagram, there is a decent amount of overlap between o365 and azure data in some regards and sign-in is one of them. That said, I believe they have different internal SLAs on delivery within MS and all things being equal I would try to have both for good coverage in case of an outage from one or the other. If I could only choose one, I'd probably go with O365.
