Re: Extend M365 Archive Quota capacity

Yes, below are the steps and considerations:

 

• Use PowerShell + Microsoft Graph API or EWS Managed API to extract mailbox content.
  • Store extracted data in Azure Blob Storage, which offers virtually unlimited capacity.
  • Automate the process with Azure Functions or Logic Apps to run scheduled exports.

 

• Considerations:
  • You’ll lose native search and compliance features unless you re-index the data.
  • You’ll need to manage encryption, retention, and access controls manually.
  • This approach is best for cold data that’s rarely accessed but must be retained.
