For businesses that use both Microsoft 365 apps and services, as well as Dropbox’s popular cloud storage and file sharing service, today could be a big day for them. Dropbox has just announced that it has launched a beta version that adds real-time co-authoring support to its service with Microsoft 365 apps.

in a blog post, Dropbox stated that support for co-authoring with Microsoft 356 apps was one of the company’s most requested feature additions. It added:

Co-authoring allows multiple team members to collaboratively edit Word, Excel, and PowerPoint files from desktop, web, and mobile, natively within Dropbox. You can also see who’s in the document and where they’re editing in real time, so everyone’s working on the latest version. Now teams can finally put an end to conflicting copies.

In addition to the Microsoft 365 co-authoring feature, Dropbox is also adding beta support for its Replay service for media files stored on Microsoft’s OneDrive. Replay allows business employees to view media files made for their company, comment on them and give final approval to these files. This new feature will allow media files stored in OneDrive to be transferred directly to Dropbox Replay.

Both the shared authority and Replay features are now available to all Dropbox customers, but they will need to sign up for beta on a specific site to get started.

The beta integrations of Microsoft 365 and OneDrive on Dropbox follow several other related improvements. Dropbox recently added improvements with Microsoft Teams. Users can now “search, preview, upload, and share content stored in Dropbox without leaving Microsoft 365.”

Another update added a Dropbox extension for Copilot for Microsoft 365. This allows Dropbox owners to use Microsoft’s generative AI assistant to ask the chatbot questions and generate summaries of content made in Microsoft 365 apps within their Dropbox account.
