Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I'm sorry. Outlook is not in Programs; it is One Drive, Teams & Edge.
Do you still see your Microsoft 365 product in the list of installed applications in Windows Settings? If so, try repairing your installation.
If Microsoft 365 / Office is truly missing, you will have to reinstall using your account.
The above will only work if you have a subscription that includes the full suite, such as Microsoft 365 Personal.
By the way, I only just noticed that you chose "Android" for operating system. Is that correct?
