Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
@Caine0001
I've had the same problem as everyone else on here with O365 these past few days and I also got my copy of O365 through the HUP programme at work as we're an MS partner.
Think I've got the same situation as you.......signed up and got a PK in the confirmatory mail and also purchased the backup disc that is exactly as you describe even down to the sticker on the back with the instructions.
its all registered to my work email address and when I go to settings on MyAccount when I log in to O365 on the web then there's no software listed for O365.
I could however remove the existing install of O365 using the tool as explained earlier in this thread and I could install from the backup disc using my PK in the mail though it does do a streaming install which is fine but it's clearly an older version.
I could also activate it ok though needed to do it on the phone as the Internet activation wouldn't work.
I then disabled automatic updates to prevent the patches being installed so whilst far from ideal I could remove/reinstall O365 and get working again on a much older version of course as it's the version on the disc as I've disabled the automatic updates.
Not sure if if helps bug it certainly backs up what you're saying re the HUP disc and programme.
