Overview
When downloading a Microsoft Excel file from an automated email report generated by your Report Mailing Settings configuration, you may encounter the following error:
Download
Not a valid file.
Cause
The Knox Manage team has identified an issue with automated email reports that contain both default and custom reports, and is working to resolve this in a future release.
Workaround
As a temporary workaround, you can make a copy of the default report to send with custom reports in your automated email:
-
On the Knox Manage console, go to Advanced > Report.
-
On the Report page, select the default report you want to include in the automated email.
Only one report can be selected at a time.
-
Click Copy.
-
Enter the Report Name and Report ID.
-
Click Save > OK.
-
Click Report Mailing Settings, select your existing scheduled email, then click Modify.
-
In the Modify Report Schedule dialogue, select your newly copied Report, then click OK.
-
Change the From Date to today.
-
Click Save > OK.
Your automated email report now contains valid file downloads for default and custom reports.
