Common Errors When Sharing Files on Microsoft 365

In the era of digital collaboration, Microsoft 365 (MS365) has become a cornerstone for businesses and individuals alike. While its tools, such as OneDrive and SharePoint, facilitate seamless file sharing, many users still make common errors that can compromise security and efficiency. Here’s a look at these pitfalls and some tips on how to share files effectively and safely.

Common Errors in File Sharing

1. Default Sharing Settings

One of the most frequent mistakes is overlooking the default sharing settings. When you share a file, MS365 often defaults to “Anyone with the link” or “People in your organization.” This can lead to unintended access, especially if sensitive information is involved. Users may not realize that they are granting broader access than intended.

Tip: Always double-check the sharing settings before sending a link. Opt for specific individuals or groups whenever possible to minimize exposure.

2. Neglecting to Set Expiration Dates

Another common error is failing to set expiration dates for shared links. This oversight can leave files accessible long after they are needed, increasing the risk of unauthorized access.

Tip: Use the expiration feature when sharing links. This ensures that access is automatically revoked after a specified period, enhancing security.

3. Not Reviewing Permissions Regularly

Once files are shared, many users forget to review who has access. Over time, team members may change roles or leave the organization, but their access may remain unchanged, leading to potential security risks.

Tip: Regularly audit shared files and permissions. Remove access for individuals who no longer need it, and ensure that permissions align with current team structures.

4. Sharing Outdated Versions

Sharing outdated versions of documents can lead to confusion and errors. This often happens when users save a new version but forget to update the shared link or attachment.

Tip: Always ensure you’re sharing the latest version of a document. Consider using version control features in MS365 to keep track of changes and maintain clarity.

5. Overlooking Sensitive Information

Users often forget to check for sensitive information before sharing files. This can include personal data, confidential business information, or proprietary content that should not be disclosed.

Tip: Before sharing, use the Document Inspector feature in Word or Excel to identify and remove hidden data or personal information. Always review the content to ensure it’s appropriate for sharing.

6. Using Insecure Communication Channels

Sometimes, users share links or files through insecure channels, such as personal email accounts or messaging apps. This can expose sensitive information to unauthorized individuals.

Tip: Always use secure, company-approved communication channels when sharing files. Stick to MS365 tools like Outlook or Teams for sharing links and documents.

Best Practices for Sharing Files in MS365

1. Utilize OneDrive and SharePoint Effectively

Both OneDrive and SharePoint are designed for secure file sharing. Use these platforms to store and share files, taking advantage of their built-in security features.

2. Educate Your Team

Ensure that everyone on your team understands the best practices for file sharing. Conduct training sessions to familiarize them with MS365’s features and the importance of security.

3. Implement Clear Policies

Develop and distribute clear file-sharing policies within your organization. This should include guidelines on who can share files, how to set permissions, and when to use expiration dates.

4. Encourage Feedback

Create an open environment where team members can provide feedback on file-sharing practices. This can help identify how people are really using file sharing and create a better balance between efficiency, productivity, and security.

5. Stay Updated

Microsoft frequently updates its tools and features. Stay informed about new security features and best practices by following Microsoft’s updates and training resources.


Sharing files in Microsoft 365 can be a straightforward process, but it’s essential to be aware of common errors that can compromise security and efficiency. By understanding these pitfalls and implementing best practices, you can ensure that your file-sharing efforts are both effective and secure.
