How to run Office 365 health, readiness, and connectivity checks?
I would recommend that you run Office365 health, readiness, and connectivity checks before you set up Office 365, Skype for Business Online or Office 365 hybrid environment.
· This test can find settings in your current environment that might cause problems when you start to set up or use your services.
· If you know where the potential roadblocks are before you start, you can fix or work around them to make your deployment path easier to complete.
The readiness checks are looking at settings in your current local network environment and anything you’ve already set up in Office 365. The checks use your credentials to make their inspection. Run the checks while connected to your current local network and logged in as an admin.
Check results are sorted into these categories:
Passed: the setting that we checked is correct for Office 365. You might want to review passed items to see what we looked at, but these results are informational only.
Warning: the setting that we checked won't break anything, but isn't optimized for Office 365. You can review the results to see if this is an important setting for you. If you want to learn more about the warning, or learn how to change the setting, you can get help from the panel to the right.
Error: the setting that we checked will negatively affect your setup and should be fixed before you continue. Definitely review these results and make changes as needed. Help on how to fix issues is available from the panel to the right. If you see an error for something you haven't set up yet, such as DNS records, you can ignore the error for now. But, we recommend you run the readiness checks again after you get set up.
