- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Collaborating with external users on shared documents.
- Observed behavior
- External users can view the email addresses and identities of other external collaborators, causing privacy and data protection concerns.
Confirm whether your organization's sharing policies allow anonymous link sharing, as this is currently the primary workaround for protecting external identities in Microsoft Word.
Use Anonymous Link Sharing via BCC
Since direct email invites expose user identities in Word, use anonymous sharing links distributed via BCC to keep external collaborators hidden.
Microsoft Word and standard Azure document-sharing settings currently do not provide a built-in feature to hide external collaborators' emails from one another. To bypass this limitation and maintain privacy, you must share the document using a public link rather than inviting users via their Microsoft accounts.
Open your document in Microsoft Word or OneDrive and click the "Share" button in the top right corner.
Click the gear icon or current permission level to open link settings, and choose "Anyone with the link".
Set an expiration date and a strong password for added security, then click "Apply".
Copy the generated link. Open your email client, paste the link into a new message, and place all external volunteers' email addresses in the BCC (Blind Carbon Copy) field before sending.
Submit a Feature Request to Microsoft
Because Azure guest settings cannot completely hide user emails in Word, reporting this privacy concern directly to Microsoft helps prioritize a future fix.
Switch to WPS Office for Secure and Flexible Document Sharing
If Microsoft Word's sharing limitations disrupt your external collaboration, try WPS Office. It provides robust, free, and lightweight alternatives for document editing and sharing, ensuring full compatibility with Microsoft Office formats while offering flexible cloud sharing options.
- 1. Download and Install: Visit the official WPS website to download and install WPS Office for free.
- 2. Open Existing Files: Launch WPS Writer and open your existing .docx files seamlessly without losing formatting.
- 3. Share Securely: Use WPS Cloud to generate secure sharing links with customized permissions for your external collaborators.
Frequently Asked Questions
Can Azure Active Directory guest settings hide external users in Word?
No, changing Azure guest-user restrictions may limit certain directory permissions, but it currently does not prevent external users from seeing each other's email addresses in a shared Word document.
Is there any way to securely share a Word document without exposing emails?
The most reliable workaround is to create a secure, password-protected "Anyone with the link" sharing link, and then distribute that link using the BCC field in your email client.
Why is seeing other users' emails considered a problem?
Sharing personal email addresses among unacquainted external volunteers or contractors can be a violation of data protection policies and privacy regulations, making it a significant compliance concern for administrators.
