Although SmarterMail has a basic File Storage function (and Connectivity to Dropbox and OneDrive), it does not have the ability to edit or create Docs and Sheets as Google Workspaces does. This is a commonly requested feature from our SmarterMail user-base. I'm not sure if it is even something that is on a future SmarterMail version roadmap (or is ever planned to be).

There is a mature Community OpenSource project called OnlyOffice Docs that has an API that allows it to be connected to a third-party application. As OnlyOffice Docs does utilize PostgreSQL I can't imagine this product (or one of similar functionality) being incorporated directly into SmarterMail, but it would be useful to have a connector in SmarterMail so that those running an OnlyOffice Docs server could directly tie it into SmarterMail File Storage so that there could be editing parity with Docs and Sheets features in Google Drive & Google Workspaces. For reference, other applications that have OnlyOffice Connectors can be found at https://www.onlyoffice.com/all-connectors.aspx

Just wanted to toss this out there as a suggestion for a future feature.
