Hi mohamad10,
Based on your post, I understand you installed Office 365 University. Since we specialize in Office 365 for business (E.g. Office 365 Small Business), there is some differences between those two products. We could provide really limited help with the issue for Office 365 University. We suggest you contact the support team below of Office 365 University for professional support:

Our support engineers there who are more specialized will be glad to help you solve the problem.
Your understanding is highly appreciated.
Thanks,
