Hi Experts,<br />
What ports do we need to open to be able to run the network performance assessment for Office 365? FYI, we are only looking to use Exchange Online, Desktop Applications (none of the Skype, Teams..etc offerings). We were able to install the executable file and for some reason can't connect to our tenant.<br />
<br />
Thanks much!
