When exporting a file via Blackbaud Hosting Services, users may receive the following error: Cannot access this file. Check security privileges over the network drive. This can occur when trying to export to a folder other than My Documents (which directs to the Hosting Files Folder).
Export the file to the [site id]$ folder, which should be the the default export path. The files can be accessed via the Files Folder.
If the suggestion above, does not resolve the issue: Contact Support and reference this article.
