Microsoft 365 Copilot is a game-changer for productivity. It serves as a powerful AI assistant, drawing on data across emails, chats, documents, and more to provide instant answers and automate tasks. But while Copilot unlocks efficiency, it also opens new doors to potential data governance and security risks.
One key concern: Copilot doesn’t always understand the sensitivity of the content it surfaces. If data is overshared or access permissions aren’t clearly defined, Copilot could unintentionally expose confidential information—especially when users rely on permissive link-sharing settings.
The Link-Sharing Dilemma in M365
Microsoft 365 enables users to collaborate quickly by sharing files and links directly in Teams and Outlook. Named links—those shared with specific users—are the most secure, ensuring access is limited to intended recipients. But users can also share more permissively using “organizational” or “anyone” links, which expand access broadly and pose a higher risk.
What’s more, when users copy and paste a link manually—without setting named access—M365 defaults to the most permissive policy set by admins. This means even sensitive content could be accessible to Copilot or unauthorized users without the data owner realizing it.
How eSHARE Solves the Copilot Oversharing Problem
Disabling copy-paste isn’t realistic. That’s where eSHARE comes in.
eSHARE Govern automatically converts pasted links into named links before they’re sent. Whether shared in a Teams chat or an Outlook email, the link is restricted to the intended recipient without disrupting the workflow.
Example: A user pastes a sensitive file link into a Teams chat with a colleague. eSHARE seamlessly converts it into a named link for that specific user, ensuring only they—and not Copilot or others—can access the file.
If the recipient is external, eSHARE Collaborate handles the conversion, applying the same secure logic for external users.
Secure Collaboration with Microsoft 365 + eSHARE
By combining M365 with eSHARE, organizations gain:
⇛ Stronger data protection against unintended Copilot access
⇛ Automatic enforcement of intended sharing controls
⇛ Seamless workflows with no extra steps for end users
⇛ Peace of mind for IT, InfoSec, and compliance teams
As organizations adopt Copilot and scale their M365 usage, eSHARE ensures governance keeps pace with innovation. Together, they deliver secure, trusted collaboration without compromise.
