We’ve all been on a team where the “final” document is called Proposal_FINAL_v3_USE_THIS_ONE_actually_final.docx. Microsoft 365 is built to stop you needing that suffix — once you and the team know which tool to use for what.
File sharing should help people work together without losing control of important information. The challenge in M365 isn’t a shortage of options. It’s that there are several — OneDrive, SharePoint, Teams, email attachments, links — and choosing the right one for the job matters more than it looks.
Personal work vs shared work
OneDrive is great for individual work. SharePoint and Teams are usually better for shared business files a whole team needs to use over time.
The simple rule: if the business depends on the file, the business should control where it lives.
If a client folder, policy document, template, contract or operations file sits only in one person’s personal storage, the business will struggle when that person is away or moves on.
Sharing links need a bit of thought
Sharing links can be very helpful — and they can quietly create confusion. People might not know who has access, whether a link expires, or whether it can be opened by someone outside the business.
A safer sharing setup should make it clear:
- who can access the file;
- whether external sharing is allowed;
- whether people can edit or only view;
- whether the link expires;
- who owns the folder.
Reduce duplicate files
The classic problem: the same document saved in three places. One version emailed, another in OneDrive, another in Teams, and no one knows which is current.
Good file structure cuts this down. Give the team one known place to work, and one clear habit: share a link, don’t send a copy.
Review permissions occasionally
Permissions don’t reset themselves. Projects end, contractors finish, staff change roles, and client relationships close. Reviewing access doesn’t need to be dramatic — it just needs to happen often enough that old access doesn’t quietly hang around.
A simple test
Pick one shared folder this week and check who has access. Remove anyone who no longer needs it, and make sure the folder has a clear owner. Repeat with the next folder next month.
A calm next step
File sharing is safest when people know where work belongs. If your team keeps asking “where’s the latest version?”, the problem usually isn’t behaviour — it’s structure. Fix the structure once and the version-suffix arms race finally ends.
