Hi @GaynWil
Thanks for visiting our forum.
Microsoft Teams tag is mainly focused on the general issue of Microsoft Teams application troubleshooting.
Do you enter this personal information in Teams?
If you only want to find chat history in the Teams client, you can press Ctrl+F to search after opening the chat interface. You can also edit or delete messages sent in Teams.
You can also query the history by admin center.
In After Office 365 admins perform a Content Search in the Compliance & Security Center, they can download chat history. Your personal chat history is actually saved in your mailbox, which means that administrators can export it as a different mailbox item.
If you're not an Office 365 admin, contact your admin to help you export it: Create a new search for your mailbox in Content Search> select Preview search results after the search is complete> your personal chat will appear as IM in Subject and Type > select Download original project to export it as an .eml file.
Your administrator can refer to this document.
Hope this helps! Moreover, if the above is not your scenario or I have misunderstood anything, please correct me and provide us with detailed information about the issue including the screenshot so that we can better understand to further assist you.
