Hi Kaushal, Just check if your web application general settings has permissive option selected. Thanks, Ibrahim

you can set the SMS provider directly in SharePoint. Please refer following link for the steps: http://kb4sp.wordpress.com/2010/09/08/setting-up-sharepoint-to-work-with-an-sms-provider/[^] hope this will help

Thanks, Ibrahim

It is really simple, Just, go to library, select the correct document, from the ribbon (assumed it is SharePoint 2010/13) go to File/Item -> Version history -> click on the Date and time link, the file will be downloaded of that version. Then you can review and do the modifications you want... hope that will help

Thanks, Ibrahim
