  Good Afternoon.

  I have been manually running an SSIS package on an adhoc basis, which populates an Excel file from a SQL Server Table. There is no apparent issue with the package, but often I get the following error:

  "External table is not in the expected format"

  And it resolves when I Shut Down and Re-Start the machine.

  Sometimes it does not work on the first run after the Re-Start but maybe the second or third run. The SSIS Container dedicated to populating the Excel file, actually fills multiple Sheets/Tabs. And when it does fail, it fails randomly on a different Sheets/Tabs (instead the same one every time). And maybe on the very subsequent run of the entire package it will run completely fine and populate all the Sheets/Tabs (without having made any modifications to the package !).

  I would appreciate advice on resolving this perplexing issue.
