Trouble with Microsoft Teams
Downloading MT onto this Dell laptop initially produced a different setup from the one which downloaded when I tried to use the guest account, so I deleted the first one in case they were incompatible.
But I couldn't log into the institution's account when invited to do so, because Microsoft identifies me by an ancient Outlook e-address which isn't, of course, the e-mail address by which the institution knows me. The institution's administrator must have put my everyday e-mail address into the invitation to join as a guest.
There's a long error message, quoting the ancient Outlook e-address, which I've sent to the administrator when asking her for help to get this guest status to work. Does she simply have to use that ancient e-address to issue me with a workable invitation? What role does one's e-address have in Microsoft Teams, other than for signing in to use the system?
