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.
- Have administrator access to the Office 365 interface
- Have the rights of Import / ExportImport / Export
- Install Azure Explorer
- Have PST
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:
|Parameter||Value / Explication|
Description: Defined in which office module the import should be done.
Description: path to the archive when uploading
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: file encoding
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.

AzCopy.exe /Source:"C:\pst" /Dest:"URI AZURE" /Y /S
