I have an open ticket with Microsoft, but the techncians assigned to the ticket don't have a clue what's going on. As we are working on some showcases on Microsoft ground and developing into the environment, we could use some of the additional features of E5. We now have this issue on three of our employees. I would love to know if there is any option to enable E5 instead of E3 on O365 Dev program. As well, I've disabled MFA and reapplied. I've removed the E3 license and reapplied. If the problem continues, please contact your support team." Skype gives the error "Can't sign in to Skype for Business.

Verify the settings below and make changes if necessary." However, on 3-4 occasions, the license change has been made, Office installed locally, and when trying to configure Outlook it gives a message "We are having trouble connecting to your account. Changing their licensing from E1 to E3 is simple enough, using the Admin Portal or PowerShell. From time to time, one of our E1 (web only) folks will be promoted into a position that requires a local installation of Microsoft Office (E3). In our tenant we have a combination of K1, E1, E3, and E5 licenses.
