Thank you for posting your question in the Microsoft Q&A forum. Regarding your issue, may I kindly ask a few question to help understand your issue better:
- Is your account a personal account (e.g., Gmail, Hotmail) or a work/school account (typically associated with a domain name like your company or school)?
- Are you trying to create the Excel workbook from within a Teams tab or app, or directly from OneDrive/Office.com?
- Does this issue happen on Teams desktop or Teams on the web?
- Have you tried creating the workbook in a different browser or in Incognito/Private mode?
- Can you provide more details about this issue if possible? Perhaps provide a screenshot (make sure to hide your personal information)
Hope to hear back from you soon.
