Adding O365 tenant requires port 4433?

New Contributor

Morning. Looking good so far so I thought I'd add in the O365 data. It took a while to figure out why it was failing but when adding a O365 tenant to Sentinel, at the completion of authentication, it jumps off to https://eus.rp.asi.azure.com:4433/OfficeOnboarding?code=xxxxxxxxxx which our firewall disproves of. Any particular reason it's not using port 443? Australia East workspace, Australia O365 tenant if that helps.

I'll go find a off-work connection to complete this one and let the good times roll. 

Cheers Al

@Eliav Levi: Is this something you can help with?

I see a little warning now in the "Connect tenants to Azure Sentinel" step that I don't remember seeing before about opening port 4433 to the web. That'll help for future users. Cheers
