Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, I'm John!
After purchasing additional storage (or freeing space), it can take up to 24 to 48 hours for everything to fully update across your account. I’d recommend waiting that time and then trying again to check emails or try to send.
If the update is still pending after 24 hours, you can try unlinking and relinking your OneDrive account, or resetting it. "Unlink and re-link OneDrive" https://support.microsoft.com/office/unlink-and-re-link-onedrive-3c4680bf-cc36-4204-9ca5-e7b24cdd23ea
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
