Journal Email Directly to Office 365 using Retention Policy

Iron Contributor

Leadership was pitched that by going to an A5 license we can ditch our current Journal Provider and use Office 365 Security & Compliance Retention/ediscovery as the primary means of journaling email. 



  • Has anyone successfully migrated to Office 365 Security & Compliance Retention for all their journaling?
    • If so:
      • Pros
      • Cons
      • Any tips.


Thank You,

Hi @Larry Jones 


this sounds interesting. Additonal question: Can you upload current data from external providers during migration?

We are using Mailstore and face problems catching all mail due to dkim / dmarc.






Sorry for not responding sooner... apparently the my RSS feed for this thread is broken..


Yes you can upload pst files using the information that's found Data Governance --> Import within Security and Compliance; however, you can't use upload one massive pst file with everyone's email. You'll have to create a separate pst file for each user and upload those files using instruction outline in Data Governance -> Import. Since were a partner with Microsoft, and that I support over 250K users this process not feasible. So Microsoft looking to develop a process that will allow to upload pst file containing all emails, just don't know when this would be available.


Hope this help
