Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
There’s no product called office 365 anymore.
it’s either Microsoft 365, which is your subscription service. Is that what you have ? If so is it Microsoft 365 personal or family? The outlook add in is only for Microsoft 365 business tier. But you should still have Teams enhanced features like longer meeting time, more participants and meeting recording, etc.
or do you have the one time purchase called office home2024? If so this doesn’t include Teams meeting enhanced features.
let me know what you have first so we can sort this out.
