Questions by product

Google Workspace FAQ

Is it possible to self-host Google Workspace services like Gmail or Docs on my own servers?

No, Google Workspace is a fully managed cloud service and does not support self-hosting any of its core applications such as Gmail, Docs, or Drive. All data and services run on Google's infrastructure, so organizations seeking self-hosted alternatives will need to consider other platforms.

Community insight informed by Reddit discussions

How well does Google Workspace support offline editing for Docs, Sheets, and Slides?

Google Workspace offers offline editing capabilities through the Chrome browser with the Google Docs Offline extension enabled. Users can create, view, and edit Docs, Sheets, and Slides offline, and changes will sync automatically once an internet connection is restored. However, offline functionality is limited to Chrome and some mobile apps, and requires prior setup.

Community insight informed by StackOverflow discussions

Who owns the data stored in Google Workspace and what control do admins have over it?

Organizations retain ownership of all data stored in Google Workspace. Google acts as a data processor under the terms of service and data protection agreements. Admins have granular control over data access, sharing policies, and retention through the admin console, but ultimate physical data control remains with Google’s cloud infrastructure.

Community insight informed by Hacker News discussions

Are there any API limitations when integrating third-party tools with Google Workspace?

Google Workspace provides extensive APIs for Gmail, Drive, Calendar, and other services, but there are quota limits on requests per user and per project to prevent abuse. Some APIs have restricted scopes requiring explicit user consent or admin approval. Additionally, certain advanced features available in the UI may not be exposed via APIs.

What are the best practices for migrating existing email and documents to Google Workspace?

Google provides native migration tools such as the Data Migration Service for emails from Exchange, IMAP, and other platforms, and Drive File Stream or Backup and Sync for documents. For large-scale migrations, using Google Workspace Migrate is recommended. Exporting data from Google Workspace is supported via Google Takeout or admin export tools to ensure data portability.

Proton Business Suite FAQ

Can Proton Business Suite be self-hosted or is it fully managed by Proton?

Proton Business Suite is a fully managed cloud service and does not offer a self-hosted deployment option. All data is stored on Proton's encrypted servers, ensuring strong privacy but requiring reliance on their infrastructure.

Community insight informed by Reddit discussions

Does Proton Business Suite support offline access to emails, calendar, and documents?

Proton Business Suite supports offline access primarily for emails via Proton Mail's web and mobile apps with local caching. However, calendar and drive components have limited offline functionality and require internet connectivity for full use.

Community insight informed by Hacker News discussions

Who owns the data stored in Proton Business Suite and how is it protected?

Users retain full ownership of their data in Proton Business Suite. All data is end-to-end encrypted, meaning Proton cannot access user content. This encryption applies to emails, calendar events, and files stored in Proton Drive.

Community insight informed by Reddit discussions

Are there APIs available for integrating Proton Business Suite with existing enterprise workflows?

Proton Business Suite currently offers limited API support focused on email and calendar functionalities. It lacks extensive APIs for drive or VPN features, which restricts deep integration with complex enterprise workflows.

Community insight informed by Forums discussions

What are the options for migrating existing emails and calendar data into Proton Business Suite?

Proton Business Suite supports standard IMAP import for emails and iCal/ICS import for calendar events. However, migration tools are basic and may require manual steps for complex data sets or large-scale migrations.
