So we've migrated from ex03 to o365. It's been running for about a month (3 weeks of which I was out on vacation). During that time I was gone, I received zero reports of issues, which I thought was impressive.
Now that I am back I am wondering how I should monitor o365? Are there any good 3rd party tools out there? Should I use SCOM? Or is the admin portal sufficient?
Thanks in advance for your input!
