Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear @Peter Konstantopoulos,
The “View Only” issue may occur intermittently when your OneDrive or SharePoint sites are in a "ReadOnly" state. If you are an administrator of the education tenant, please review the site Lock State and unlock it if it is set to ReadOnly. You may follow the guidance provided in the article below for detailed instructions on how to check and manage the lock status: Lock and unlock sites - SharePoint in Microsoft 365 | Microsoft Learn
If the site is already unlocked and the issue persists, I strongly recommend contacting Microsoft Support. The support team can investigate further with the back-end team to determine whether your tenant has been restricted from editing due to an underlying issue or an unintended action. To create a support ticket, please refer to the following article: Get support - Microsoft 365 admin | Microsoft Learn
If you are an end-user, please help me to reach out directly to IT Admin for further support.
Additionally, since you are using an education tenant, you may need to verify certificates or domain configurations required for educational use.
Please feel free to let me know if you have any further questions or concerns.
