Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi, I'm John! I will help you with this.
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 send your emails.
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: Mac" https://support.microsoft.com/office/unlink-and-re-link-onedrive-3c4680bf-cc36-4204-9ca5-e7b24cdd23ea#id0ebbh=mac
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
