Does SharePoint Work for Internal Communications?

Walk into almost any large organization, and the internal communications run on SharePoint… Not because anyone chose it for the job, but because it came bundled with Microsoft 365.

Microsoft 365 has passed 450 million paid seats, and SharePoint is included in those subscriptions, so most organizations end up with it as their intranet by inheritance rather than by decision.

For part of internal communications, it is genuinely good. For the rest, it quietly works against you.

SharePoint was built as a document management system, and it still behaves like one.

Using SharePoint for internal communications means leaning on a tool that stores information well but rarely moves it to people, which is why about half of internal communicators are dissatisfied with their channels' ability to reach every employee.

The fix is usually to add in what SharePoint lacks: something like an internal podcast.

What SharePoint Does Well for Internal Communications

SharePoint earns its place for real reasons, and a few of its strengths carry directly into internal communications.

It centralizes content. Policies, decisions, process documentation, and reference material live in one searchable place, with version control and a document library that keeps the source of truth in a single spot. For a large organization, that alone is worth a lot.

Its permissions are granular. Access flows from the same identity model as the rest of Microsoft 365, so a communication site can be scoped to a region, a department, or a project without standing up a separate system or managing a second set of logins.

It also integrates across the stack. SharePoint sits within the Microsoft 365 ecosystem alongside Teams, Outlook, and Viva, so a communication site, a document, and a meeting can reference each other without anyone having to leave the tools they already use. For content that lives or dies by being organized, permissioned, and findable, SharePoint does the job well.

Where SharePoint Falls Short for Internal Communications

SharePoint's weaknesses for internal communications all surface at the same stage: getting a message to employees.

Four of them matter most.

Employees Have to Come to SharePoint

SharePoint is a destination, a place people log into when they need a document. Communication works the other way around, pushing a message out to people who weren't already looking for it.

A SharePoint news post sits on a page most employees never open unless something else points them there, so the message waits instead of arriving.

Frontline and Deskless Workers Get Left Out

Retail staff, warehouse workers, drivers, and nurses rarely sit at a desk with the intranet open.

SharePoint's document-first design and desktop habits mean the people who make up most of the workforce receive a fraction of the company communication that head-office employees do.

There's No Native Way to Deliver Audio

SharePoint can store an audio or video file, but it has no native way to deliver it the way people consume media now, on a phone, in a podcast app, between tasks.

Long-form leadership content ends up as an attachment that few employees open, so the format that builds the most connection rarely gets used.

You Can't See Whether a Message Reached Anyone

SharePoint reports page views and document opens, not whether a message reached the employees it was meant for. Comms teams are left guessing whether their work made it past the people already paying attention.

None of these sink SharePoint as a document hub. Together, they explain why so many internal communications programs feel busy and still fail to reach the workforce.

Using Supporting Cast to Close the Gaps in SharePoint for Internal Communications

The fix for SharePoint's weak spots rarely calls for a rip-and-replace project.

SharePoint is already wired into Microsoft 365, your permissions, and your document library, and tearing it out to solve an engagement problem usually creates a bigger one. The smarter move is to leave SharePoint in place and pair it with a channel built to reach people.

That missing part is almost always the same: actually reaching employees. Audio is what closes it.

A leader's message delivered as an internal podcast reaches people through the podcast apps they already use, like Apple Podcasts and Spotify, during commutes and between tasks, without asking them to log into an intranet they rarely open.

Supporting Cast is built for exactly that layer. It ties access to your identity system, so listener groups update as people change teams, and runs without the IT tickets a new SharePoint workflow demands.

SharePoint stays the system of record, and Supporting Cast becomes the channel that actually reaches the workforce.

Stop Asking SharePoint to Be a Channel It Was Never Built to Be

When internal communications underperform on SharePoint, the instinct is to push the comms team harder or assume employees don't care.

The real cause is simpler: a document system is being asked to do a broadcast channel's job, and low engagement is the result of that mismatch.

That changes what good internal communications even means.

The measure stops being how much content sits on the intranet and becomes how much of it reaches the people it was meant for. SharePoint can hold the first; it was never going to deliver the second.
