Sharepoint 'unknown error trying to lock file' RRS feed

  • Question

  • Can anyone please help I have an issue with Sharepoint. I use windows 7 and when I open any word/excel document on Sharepoint when I click edit workbook I get the error message 'unknown error trying to lock file'. I have tested other machines and it works fine on xp but not windows 7. Has anyone come across this before?

  • Hi DavidGlobo,


    From your description, I understand that you click the word/excel document on SharePoint, it opens in read mode, you click edit document, error message occurs “unknown error trying to lock file”, if I have any misunderstanding, please feel free to let me know.


    If so, would you please try select “Edit in Microsoft Office Word/excel” from the drop down menu of item in SharePoint, check whether it still causes the error.


    If it persists, there is a KB article about “Office 2003 and 2007 Office documents open read-only in Internet Explorer”, the scenario of your issue is very similar to the issue fixed in this KB article, I suggest following the resolution and checking. For more information, please refer to:
