Excel Export Error: Store must be open for this operation

Question

Hi,
I’m currently running into an issue exporting Reporting Services reports to Excel that I haven’t encountered before. Unfortunately, I’m not able to find much information
about this error directly related to SQL Server Reporting Services. The error occurs on multiple reports with a varying number of rows (static columns). The reports are simple list reports with no custom code, etc.
Currently running SQL Server 2012 and SharePoint 2013. Here’s the related error in the SharePoint ULS log:
Microsoft.ReportingServices.ReportProcessing.UnhandledReportRenderingException: An error occurred during rendering of the report. ---> Microsoft.ReportingServices.OnDemandReportRendering.ReportRenderingException:
An error occurred during rendering of the report. ---> System.ObjectDisposedException: Store must be open for this operation.

Thoughts, comments or suggestions?
Thanks!

Hi K. Beckett,
Based on the error message, the issue may be a timeout issue related to the structured storage which is used as a container for storing binary Office documents. As I know, the structured storage is only used to store OLE objects or macros in Office Open
XML documents. By default, SSRS 2012 use Office Open XML format when exporting a report to Excel. To check whether your report server uses Excel renderer (xls) or ExcelOPENXML renderer (xlsx), please export another report and check the file extension. If it’s
an .xls file, it means that you have enabled Excel 2003 renderer for SSRS 2012. Besides, the name should be Excel 2003 in the drop down list of the Export option if you have enabled the Excel renderer in the rsereportserver.config file, and the EXCELOPENXML
renderer displays as Excel in the drop-down list of the Export option.
So, if you are using the Excel renderer instead of EXCELOPENXML renderer, use the EXCELOPENXML to see if the issue persists.
If it is not the case, I suggest that modify the timeout value for the SharePoint Web Application and the report execution timeout.
