Backup emails on Microsoft 365

Hi Freelancers,

I'm looking for a dev be able to manage my project.
Most of the project is about connecting to mailboxes with API
Microsoft is proposing EWS APIs to do this

I would like to use this to make backups.

To start, I just need to POC and confirm it is possible and reliable.

I can provide mailboxes to test.

Please contact me if you are able to help and provide a very good job.

Regards
Raphaël
