Hi, Lwin Myo Hein

Welcome to Microsoft Q&A forum.

Sorry for this frustrating experience that you're encountering. This usually happens when Excel for the web can’t keep a stable sign-in “session” in Edge (so it expires and refreshes), and at the same time the workbook is being held by a leftover edit lock (sometimes by you from another device or a prior crash).

Here are some suggestions you can try:

Release the workbook lock first: Close the file everywhere (Excel desktop app, other browser tabs, phone, Teams preview). If it was left open or didn’t close cleanly, the service may still think it’s in use and needs a few minutes to clear.

Check if someone else is editing or using a non-coauthoring Excel version: If one person opened it in a version that doesn’t support co-authoring, everyone else can get a “locked” message in the web app. Asking them to close it often resolves it immediately.

Reset the Edge sign-in session for Office: In Edge, clear site data just for office.com and your SharePoint/OneDrive site, then sign out of Office on the web and sign back in. Corrupted cookies or mismatched tokens commonly cause “session expired” loops even when you appear logged in.

Try InPrivate or temporarily disable extensions: Ad blockers, privacy extensions, and strict tracking prevention can block the cookies Excel for the web uses to keep your session alive, which can trigger repeated refreshes.

Quick workaround to keep working: Open the file in Excel desktop app or make a copy in OneDrive/SharePoint, edit the copy, then merge changes back once the lock clears.

Hope this helps. Feel free to get back if you need further assistance.
