Custom Teams Cloud Store Provider

Occasional Contributor



I am developing an app for Microsoft Teams which interacts with our cloud service and I would like to know how to integrate a custom cloud storage provider into Teams (Teams: Files -> Add cloud storage). Currently I have only the options "Citrix files", "Dropbox", "Box" and "OneDrive", but I would like to have a custom option to add our cloud service.


I could not find any hints about extending this in the app manifest description ( nor any hints in the Microsoft Teams app developer reference.


How can I do this?


Thank you and Regards,

Did you ever find out how to do this?

I am looking for the same information.

@dhoelzl were you ever able to resolve this ? I would also like to know how to integrate a third party storage product into MS Teams.
