pst mapping fails

[edie209]

I have uploaded all my users pst files to be mapped to Office365, using Azure storage explorer I can see all the pst files in the ingestiondata folder.

 

However when I run the "upload email messages (PST files)" from the Exchange online management console it sits at 0% for about two hours and then fails. But there is no explanation, here is an example of the mapping file I am using

 

Workload,FilePath,Name,Mailbox,IsArchive,TargetRootFolder,SPFileContainer,SPManifestContainer,SPSiteUrl
Exchange,,user.pst,[email protected],FALSE,Inbox,,,

 

[email protected] is the primary email address

 

Everything worked when we tested this on one user before the summer holidays, and I can manually import the users pst file using Outlook

 

Does anyone have any ideas? have I missed something?
