Preparing the data for import

Be aware of the following pre-requisites when preparing your data.

  • Emails can be provided in either PST or EML format
  • EML files must be compressed into either Zip or 7zip files.
  • The maximum PST file size is 10GB per file.  
  • The maximum Zip/7zip file size is 80GB per file.  
  • Multi-part Zip & 7zip files are not supported.

Uploading the data for import

  • Proofpoint will respond to the import ticket request with SFTP credentials of where your organizations data should be uploaded.
  • You will need to notify Proofpoint once all the data has been uploaded.
  • Proofpoint will provide confirmation and output of all files uploaded (including size) before proceeding to the next step.

Data Verification During Import

  • Once a file has been uploaded to the SFTP site its file name will be re-written to indicate that it is undergoing verification:
    • e.g., (verifying...)
  • If verification fails the import job cannot proceed until verification passes.
  • Problem files will be suffixed with a verification failure reason:
    •  - The zip is encrypted but no password was supplied.
    • - The zip password is incorrect.
    • - The file is not supported.
    • - Multipart zips are not supported.
    • - File is corrupted.
    • - Unknown error.
  • Where verification is successful, the existing upload process continues and progress is reported:
    • (uploading 14%)
  • When fully uploaded the file finally displays as it's original filename:

 Import pre-processing

  • Once all data has been uploaded and verified, Proofpoint will unpack all data supplied and extract and verify all messages. 
  • This phase will produce a preliminary import report that will be shared. It includes individual message counts and will identify counts for duplicates, problem messages, etc.
  • Approval is required to proceed to the next step

Import Processing 

  • This phase will process and move the data to the customer's production archive.
  • There are no actions for customers during this phase.

Import Completion Confirmation 

  • A final import report is shared once import processing has completed. It will include final counts of all processed email.
  • Customers are given 10 days to verify the import (via search and reports). 
  • Import requests are closed 10 days after the import completion was indicated as or when confirmation has been provided.

Archiving Engineers suggest to wait up to 24 hours to see all emails (internal and external) in the archiving admin dashboard.
