People rarely complain about SharePoint because of a missing feature. They complain because they cannot find anything, do not know where to save a file, or have been added to forty Teams and cannot tell which ones matter. Those are real problems. They are usually operating-model problems rather than product problems.
Too many places to put things
When Teams, SharePoint sites, OneDrive folders, and legacy file shares all hold similar content, people save files wherever is most convenient and search wherever they last found something. Over time, nobody is sure which copy is current.
A simple, communicated rule helps more than any setting: personal working files in OneDrive, team collaboration in Teams and their connected sites, and organization-wide reference content in a small number of well-owned SharePoint sites.
Nobody decides when a workspace ends
Teams and sites are easy to create and rarely closed. Projects finish, groups reorganize, and the workspaces stay behind with outdated content and members who no longer need access. Naming conventions, ownership requirements, and a review or expiration process keep the collaboration space from growing faster than anyone can understand it.
Permissions that made sense once
Sharing a folder with the whole organization to solve an urgent problem, or inviting a guest who never gets removed, are small decisions that add up. Periodic access reviews for sensitive sites and external sharing keep the environment closer to what the organization intends.
Training on how, not just what
Most Microsoft 365 training focuses on features. What people need more often is guidance on how their organization uses those features: where a department's documents live, when to start a new Team versus a channel, how to share with a client. That guidance is specific to each organization, which is exactly why it is so often missing.
Fixing collaboration in Microsoft 365 rarely requires replacing the tools. It requires deciding how they should be used, then setting them up and maintaining them so that the decision holds.
