Word and Excel Save & Send Do Not Work - ost File Cannot Be Accessed

Ladies and Gentlemen

We have approximately 38 Windows 8.1 Professional users and we are using Office 2010 with an Exchange server.  We are not using Lync or any unified communication software.  I have one user who frequently uses “Save and Send” while using Word or Excel.  While this feature seems to work fine in all of the workstations that I have checked, it does not work on this user’s machine.  When “Save and Send” is selected in either Word or Excel and “Send as Attachment” is selected, the user receives the error:  “The file C:\Users\User.Domain\AppData\Local\Microsoft\Outlook\user@domain.com.ost is in use and cannot be accessed.  Close any application that is using this file, and then try again.  You might need to restart your computer.”  

I have tried starting Word in safe mode to see if there was an add-in causing the problem, but I still received the error.  I tried using the Inbox repair tool which indicated there were errors and that it finished, however, the problem still exists.  I tried turning UAC off.  It did not help.  I tried repairing Office, but the problem still occurs.

Any ideas will be greatly appreciated.

Sincerely

Jebidieh

The .OST file is the Exchange offline store so I would start by checking if anything else is using it - for example: can you rename it when Outlook is closed? if there is a background sync  - eg: onedrive,  backup or Malware holding it open you should get a failure and you can start identifying the culprit.

Assuming you can rename it then change it to something like '.tmp' and restart outlook, the OST should be recreated and that might fix the problem. Failing that an account reset and/or reinstall of outlook would be my next attempts

Hi Regmigrant!

Thanks again for your suggestions, but they did not work.  We uninstalled Microsoft Office, ran cCleaner and re-installed Office.  To my surprise (I expected some of the settings to still reside on the computer when Office was reinstalled and the problem to still be there) it worked.  The problem has been resolved.

Thanks again for your help!

The suggested solution did not resolve our problem, but certainly gave us other troubleshooting tools to help eliminate other possibilities before re-installing the software.
