As you might have seen, along with performance tuning related work, I also help community in getting answers to questions and troubleshoot issue with them. A few days ago, one of community leader and user group champion contacted me for assistance. He informed me that they are using Microsoft Access Database Engine 2010 provider to read data from an excel file. But they are seeing below error while doing test connection. Let us learn about error related to OLE DB provider.
Cannot initialize the data source object of OLE DB provider “Microsoft.ACE.OLEDB.12.0” for linked server “EXCEL-DAILY”.
OLE DB provider “Microsoft.ACE.OLEDB.12.0″ for linked server ” EXCEL-DAILY” returned message “Unspecified error”. (Microsoft SQL Server, Error: 7303)
This error appears only from the client machine, but test connection works fine when done on the server. The same error message is visible via SSMS.
EXEC master.dbo.sp_addlinkedserver @server = N'EXCEL-DAILY' ,@srvproduct = N'Excel' ,@provider = N'Microsoft.ACE.OLEDB.12.0' ,@datasrc = N'D:\EMPLOYEE_ATTEN_DATA.xlsx' ,@provstr = N'Excel 12.0; HDR=Yes'
After a lot of checking, we found that the account which was used from client and the server was different. So, I have captured Process Monitor for both working and non-working test connection. It didn’t take much time to see below in non-working situation.
sqlservr.exe QueryOpen C:\Users\svc_app\AppData\Local\Temp ACCESS DENIED
WORKAROUND/SOLUTION
So, we went to the SQL Server machine and gave full permission to the file path which was listed in process monitor as access denied. C:\Users\svc_app\AppData\Local\Temp.
After permission was given test connection worked and client machine could read data via excel using linked server.

Having the same problem. I’m getting “NAME NOT FOUND” HKUS-1-5-80-3880718306-3832830129-1677859214-2598158968-1052248003_CLASSESMicrosoft.ACE.OLEDB.12.0CLSID
Does this mean anything?
Not sure if that key is suppose to be there.
Thank you. That solved my problem. Mine was the same problem . AccessDenied on SQL Temp folder.
I am able to create linked server with the above mentioned script, but cannot read excel file with the below query..
SELECT * FROM OPENROWSET(‘Microsoft.ACE.OLEDB.12.0’,
‘Excel 12.0 Xml;HDR=YES; IMEX=1; Database=D:\Desktop\task.xls’,
‘Select * from [Sheet1$]’)
I get the below error:
OLE DB provider “Microsoft.ACE.OLEDB.12.0” for linked server “(null)” returned message “Unspecified error”.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider “Microsoft.ACE.OLEDB.12.0” for linked server “(null)”.
It means that the file is residing in your system. Make sure it is in Server’s directory

Make sure the file is available in Server’s directory
What do you mean with Server’s directory? The data files are normally in an location where datafilee are stored. D drive as an example. But yes it’s local on the server.
The Server is running with a domain service account. I’ve also read a lot about setting security on the temp folder or the file location. But what exactly?
Allow the Domain service account (running the SQL Server) with full access on the XLSX file location?
or
Allow the actual logged on account running management Studio with full access to the temp folder of the domain service account( running the SQL Server)?
The file should be available in the directory where SQL Server is installed. Otherwise you need to use the UNC path
