Where Teams Chat Data Is Stored and How to Retrieve It
You keep Teams chat messages and files in certain Microsoft 365 places.
Personal or group chat files are saved in the "Microsoft Teams Chat Files" folder in your OneDrive for Business.
Files shared in channels are put in your team’s SharePoint folder.
You share OneDrive files only with people in the chat. Teams chat history is stored in hidden mailbox folders, not like Skype for Business. You cannot see these folders in Outlook. You need special tools like eDiscovery to find old chats.
Key Takeaways
Teams chat messages are kept in hidden folders in Exchange Online mailboxes. You cannot see these messages in Outlook. This keeps your chats safe and private.
Files you share in personal chats go to your OneDrive for Business. Files in team channels save to SharePoint. Only people in the chat or team can get to these files.
You can search your Teams chats with the search bar. You can use filters and special commands to find messages quickly.
Admins have special tools like Microsoft Purview eDiscovery. They use these to search and export Teams chat data for legal or compliance reasons. Regular users cannot use these tools.
Backing up Teams chat data by hand is slow and does not save everything. Retention policies and third-party backup tools help keep your data safe. They also make it easier to get your data back.
Teams Chat Storage
Personal and Group Chats
Teams chat messages are kept in Exchange Online mailboxes. Each message you send or get goes into a hidden folder. You and the person you chat with both have a copy. These folders do not show up in Outlook. You cannot open them yourself.
Microsoft Teams uses your Preferred Data Location to pick where to keep chat data. If your PDL changes, Teams moves your chat data to the new spot.
Teams chat messages use an Azure chat service for main storage. Exchange Online keeps a copy to follow rules.
Different mailbox types hold different chat data:
UserMailbox is for private chats and cloud users.
MailUser is for users on local servers.
Retention policies can remove messages from Exchange mailboxes and Azure chat service.
Note: You cannot see Teams chat history in your Outlook Conversation History folder like you could with Skype for Business. Teams keeps your chat data safe and hidden to follow rules.
Channel Messages
Channel messages are stored in a different way. When you post in a team channel, Teams saves it in the Office 365 Group mailbox for that team. Each team has its own group mailbox. Teams uses the group’s PDL to pick where to keep channel messages. If an admin changes the group’s PDL, Teams moves the channel messages to the new spot.
You cannot open these hidden folders in Outlook. Only special admins can search them with eDiscovery tools. This setup keeps your Teams chat data safe and helps with legal needs.
Teams Chat Files
OneDrive for Business
When you share a file in a Teams chat, it goes to your OneDrive for Business. The files are in a folder called "Microsoft Teams Chat Files." Only people in your chat can see these files. You can let others view or edit the file by changing settings in OneDrive.
If you want to share with someone outside your company, you can send a safe link. Add their email and pick what they can do. Sometimes, your company may not let you share with people outside. If guest access is turned on, outside users can open files after you let them. You can also use links for "anyone," but your company might not allow this.
Tip: Use "Manage Access" in OneDrive to see who can open your files. You can change who can see or edit your files any time.
Here is how file access works in chats:
SharePoint Online
Files shared in Teams channels are saved in SharePoint Online. Each team has its own SharePoint site. Regular channels use folders in the main library. Private and shared channels have their own SharePoint sites with special rules.
You and your team can open channel files from the Files tab in Teams or in SharePoint. Who can see or edit files depends on your team role. Team members can usually edit files. If you want to add someone not in the team, you can use SharePoint settings to let them in.
Visitors can see files if you let them in SharePoint.
Outside users need you to give them permission in SharePoint.
SharePoint helps you manage files, see changes, and control who can use documents. This makes teamwork easier and keeps files neat.
Retrieve Teams Chat Data
User Search Methods
You can look for Teams chat messages using search tools. The search box is at the top of Teams. Type a word, phrase, or someone's name. Teams shows results while you type. To see only chat messages, pick 'Messages' after searching. Press Enter to see all results for your search.
Filters help you find things faster. You can choose chat type, sender, date, or attachments. If you want to go to a chat or channel, type /goto in the search box. Pick the name you want. In a chat or channel, press Ctrl+F (or Cmd+F on Mac) to search just that conversation.
For harder searches, use special words. Type From:Alex to find messages from Alex. Type In:ProjectTeam to look in a certain channel. You can also search by date or subject. These tools help you find messages quickly, even if you have lots of chats.
Tip: Use filters and search words to find messages faster.
Admin Tools
Admins can find Teams chat data for everyone in the company. They use tools like Microsoft Purview eDiscovery and Content Search. These tools let admins search all Teams chat messages, channels, and files. Admins can make cases, set up searches, look at results, and export data.
To use these tools, your company needs the right Microsoft 365 license, like E3 or E5. Admins need special permissions, such as being in the eDiscovery Manager or Administrator group. With these roles, admins can:
Make and manage eDiscovery cases.
Put holds on Teams chat data to keep it safe.
Search for messages, files, and meeting content.
Export results in formats like PST to open in Outlook.
Admins can search by words, sender, date, or message type. Private channel messages are saved in each member's mailbox. Shared channel messages are in system mailboxes. Files shared in chats and channels are saved in OneDrive or SharePoint. Admins may need to search those places too.
Note: Only admins with the right permissions can use eDiscovery and Content Search. Regular users cannot use these tools.
Export and Backup
Exporting and backing up Teams chat data is not easy. Teams does not have a button to export chats. You have a few choices, and each has good and bad sides.
Copying text or taking screenshots works for small chats. It takes a long time for big chats. These ways do not keep details like time, sender, or edits. Printing to PDF is fast but does not show deleted messages or details.
Admins can use Microsoft Purview to export Teams chat data. This needs special licenses and setup. The exported data comes in files you open with Outlook. This way is best for legal or compliance needs, not for daily backup.
Third-party tools help you back up and restore Teams chat data. These tools give you more control and make it easier to get back lost messages. Some tools let you back up all messages and files. You can restore them if needed. They are easy to use and work well for big companies.
Best Practice: Use both archiving and backup tools. Set up retention policies and use third-party tools for extra safety. This helps you follow rules and keeps your Teams chat data safe.
Many people have trouble backing up Teams chat data. Manual ways are slow and miss details. Admin tools need special permissions and licenses. Third-party tools have more features but may cost more. Always plan your backup to protect your data from being deleted, hacked, or lost.
Teams chat messages are saved in hidden Exchange Online mailboxes. Files from chats go into OneDrive or SharePoint. You can find and back up data with search tools. Microsoft retention policies help keep messages for a set time. Third-party backup tools can do automatic backups and use encryption. They also help you get your data back fast. Many companies trust third-party tools to protect Teams chat data. To follow rules, make clear policies and teach users what to do. Watch activity with built-in or outside tools.
Remember, using both retention policies and automatic backups keeps Teams chat data safe and easy to get.
