Can Slack admins read your DMs?

Can your boss see your Slack messages?

It might not be what you want to hear, but yes—your manager could potentially read your private Slack messages. That said, it’s not as simple as them just opening up your chat history. Whether they can access your messages depends on the Slack plan your company is on, its Slack workspace settings, and the established internal privacy policies.

In other words, no one can just casually peek into your DMs. Your employer would either need your permission or have to go through a formal process—usually by submitting a request to Slack and providing a valid reason, like a legal or compliance investigation. So, they’d only be able to export messages from your private channels and DMs if Slack approved their request.

Should that ever happen, don’t bother editing or deleting your DMs—it won’t make any difference. Slack stores all the original versions of your messages on its servers. So, once you send something, it’s technically there for good.

Also worth noting: anything you post on public channels is automatically visible to everyone in the Slack workspace—no special permissions needed.

So, can Slack admins read user DMs?

As you can probably guess, the answer is still a “yes”—but with a few caveats.

Slack admins in your company are responsible for things like access permissions, legal compliance, and integrations. Basically, they’re the ones running the Slack show. This means that, in some situations, they can technically have access to your direct messages in Slack. But here’s the key part: they can't do it by default. There are data privacy rules and Slack policies in place to prevent casual snooping. Access to private messages only happens under specific circumstances.

If your company uses Slack’s Enterprise Grid or Business+ plan, some admins—usually people working in IT, compliance, or HR—can be given the option to export data from Slack, including all private messages. It’s a feature mostly meant for large organizations that need to stay on top of compliance and legal requirements. But for this to happen, admins have to put in a request directly to Slack—and Slack won’t approve it unless they’ve got a really solid legal or compliance reason.

On Pro and Free plans, things are a lot more limited. Admins can only export messages from public channels. That said, in the case of a serious breach or legal investigation, even on these plans, a company can submit a formal request to Slack for access to private data. And if the situation is serious enough, Slack will likely grant it.

So, are your Slack messages private? Technically, yes—at least until something happens that prompts an investigation. If that day comes, Slack admins could gain access to your messages so they can be reviewed.

Types of data that can be exported from Slack

With all this talk about who can download what on which Slack plan, it’s totally fair if you’re feeling a bit dizzy and wondering what it means for the privacy of your messages. To help clear things up, check out the table below—it lays out exactly what kind of data admins can access, based on the company’s Slack plan.

*Workspace owners and organization owners need to submit a request to enable these types of exports.

So if you’re still wondering, “Can Slack admins see private channels?”—the short answer is “technically, yes.” However, their access depends on which Slack plan the company is on, and whether Slack approves their request to check your private messages.

Is it similar with tools like Microsoft Teams?

Yes, very much so. Just like with Slack, your employer can get access to your messages on Microsoft Teams—provided they’re on the right subscription plan. The only difference (though it might feel like a big one) is that with MS Teams, admins do NOT need Microsoft’s approval to view private messages within the organization.

So, if your company is on the E3 or E5 Office 365 Enterprise plan, your admins can use features such as eDiscovery to search for and export data like:

• One-on-one, group, and meeting chats

• Private channel messages

• Meeting chat logs

• Recorded meetings and transcripts

• Files that were shared as attachments

That said, it’s probably not like someone is sitting there reading your messages all day. These data monitoring tools are mainly in place for security, compliance, and legal reasons—for example, if there’s a data breach. In day-to-day operations, your messages are most likely just stored safely in the background.

But if you’re specifically asking: “Can Microsoft Teams be monitored by my boss?”, the answer is: “Yes, it sure can be.”

How to act responsibly on Slack

Since Slack is meant for work-related communication, it’s probably not the best place to overshare or drop sensitive info without a second thought. Here are a few handy tips to help you stay clear, professional, and safe while chatting with your team—without putting yourself (or anyone else) in a tough spot.

Be respectful—no matter who you’re chatting with

Everyone in your organization deserves to be treated with kindness and respect. As part of the team, you must always communicate in a professional manner—whether you are chatting in person or online. If someone’s giving you trouble, it’s best to talk to your supervisor about the situation, without letting your emotions take over and writing something on Slack that could negatively affect how others perceive you.

Be mindful about sharing personal stories

It’s perfectly normal for people to form friendships at the office—after all, many—if not most—of us spend more time with our coworkers than with our friends outside of work. That said, it doesn’t mean you should treat Slack like your personal messaging app and use it to have casual, buddy-buddy conversations with your teammates. Keep in mind you’re still at work, and some things are better saved for when you’re hanging out with the team outside of work hours.

Avoid sharing confidential business information

What’s really important is that you use Slack for things like collaborating with your team on your daily tasks, scheduling meetings, and sharing updates on marketing campaigns. This is to say that you should never put sensitive data—like client information, company secrets (such as proprietary designs), passwords to business accounts, or credit card details—in a post or message on Slack. If you need to share something sensitive, like corporate credentials or credit card information, it’s better to use a tool like NordPass, which keeps everything encrypted. And if you’re unsure about what’s safe to share on Slack, it’s a good idea to check with your IT department for guidance.

Stay informed about Slack’s privacy settings

Remember that your employer could potentially access your private messages and channels at any time. Right now, your messages are usually only reviewed by admins if there’s a serious investigation, like checking if you’ve crossed any lines or if your actions contributed to a legal issue or data breach. But these rules could change, so it’s a good idea to stay on top of any updates to your organization’s Slack privacy policy in the future.

Bottom line

If your company uses Slack, your employer might be able to see your messages in private chats and channels—but it depends on your company’s Slack plan and whether Slack agrees that your boss has a good reason to see your DMs.

That said, it’s always a good idea to keep things professional in your Slack messages and avoid sharing sensitive information like customer data or corporate passwords. If you do need to share business credentials with your teammate, make sure to do it using a secure password manager like NordPass to keep everything safe and sound.
