Upload PSTs on Office 365 and import into accounts


When migrating to Office 365, you may need to return the history of old mailboxes in the news using the PST archives.

There are several ways to do this:

  • Import from the Outlook client directly (I highly recommend this solution).
  • IMAP copies from the Office 365 migration interface.
  • Send PSTs on Microsoft servers for import.

In this article, we will see the third solution.

Prerequisites

  • Have administrator access to the Office 365 interface
  • Have the rights of Import / ExportImport / Export
  • Install Azure Explorer
  • Have PST

Correspondence file

The first step is to fill in a correspondence file to link the archive to the email account.

The file must be in csv format with a comma (,) separator.

Here is the header that must have your file:

Workload,FilePath,Name,Mailbox,IsArchive,TargetRootFolder,ContentCodePage,SPFileContainer,SPManifestContainer,SPSiteUrl

 

Parameter Value / Explication
Workload Value: Exchange
Description: Defined in which office module the import should be done.
FilePath Value: empty
Description: path to the archive when uploading
Name Valeur: archive-jdupont.pst
Description: Name of the pst file sent
Mailbox Value: [email protected]
Description: The main email address of the account where the archive is to be sent.
IsArchive Value: TRUE / FALSE
Description: Determines whether the file should be imported into the archive mailbox.
TargetRootFolder Value: empty or / and / MyPst
Description :

  • Empty: the file will be imported into a folder at the root named “imported”
  • /: Items will be imported directly into the inbox. This option allows you to rebuild the tree structure
  • / MyPst: the import will be done in a folder named my PST at the root of the box
ContentCodePage Value: empty
Description: file encoding
SPFileContainer Value: empty
SPManifestContainer Value: empty
SPSiteUrl Value: empty

Here is an example of an import file:

Workload,FilePath,Name,Mailbox,IsArchive,TargetRootFolder,SPFileContainer,SPManifestContainer,SPSiteUrl
Exchange,,archive-rdr.pst,[email protected],FALSE,/,,,
Exchange,,archive-jbo.pst,[email protected],FALSE,/,,,

Now that the file is ready we will go to upload files.
