Hi @KKB
Are these shared collaborative workbooks that occur with this issue?
Could you please check the version name and version number? This information is under "Product Information", you may open Excel, click "File" > "Account".
- If it is Microsoft 365 Apps, I suggest you click: Options > Save, uncheck "AutoSave files stored in the Cloud by default in Excel".
Then sign out your account from Excel, then close it.
Click Start > Control Panel > User Accounts > Credential Manager> In the Windows Credentials section, remove all stored credentials referencing the OneDrive and Microsoft Office.
- Note: Under Generic Credentials, look for any entries containing “OneDrive Cached Credentials” and MicrosoftOffice16 and MicrosoftOffice15 credentials and Remove all.
Open Excel, re-sign in your account.
