Unexplained AAD Sign-in Activity

Hi all,

I wasn't sure if this was the right forum to ask this question as it concerns both Office365 and Azure AD sign-in logs but this is m first port of call...

I've noticed some unusual sign-in activity on Azure AD logs. The application on the logs is showing as Microsoft Office but the browser is logged as IE 7.0 running on Windows 10.

It's unusual from my perspective to see IE7 considering we don't have IE7 on the network, and certainly not on a Windows 10 machine. The resource is OCaaS Client Interaction Service which I suspect may have something to do with it.

Do certain resources use elements of IE7 to present MFA screens and present themselves as using that client on logs?

@Computato-1855 That seems to be with Microsoft teams application, which uses older version of browsers to perform some application activity.
A similar scenario for Google Chrome was found here at : https://techcommunity.microsoft.com/t5/microsoft-teams/teams-user-agent-chrome-66/m-p/1114304

The best people to answer this will be the MS teams support team, if you want to know why It uses older versions of browsers.
If your query is more towards this particular sign in event, then you can treat it as a MS teams service application performing some activities.
