Issue

Administrators may experience slow download performance when exporting Archive Search metadata via the Mimecast Administration Console.

This is being investigated by our engineering team.

Workaround

While a resolution is being worked on, there are two available options to obtain Archive Search metadata export reports:

• Wait for the export to complete
  If you initiate a metadata export from Archive Search in the Mimecast Administration Console, allow additional time for the export to complete. Exports can take a few minutes before the download is available.

• Use Case Review to export metadata
  As an alternative to exporting directly from Archive Search, you can use the Case Review app:

  • Open the Case Review app.
  • Create an Archive Search.
  • Create a new export.
  • When configuring the export, set the Data Type to Metadata Only.

  This Case Review export provides a similar metadata report with even more metadata fields than the Mimecast Administration Console metadata export.
