Text-based conversations between users with searchable history in Microsoft Teams Free
Hello Araceli Cardenas,
I’m sorry this happened. You were right not to give them your bank information.
Since the conversation happened in Teams, please report a message in that chat using More options > Report a concern, then block the contact. Microsoft can review the report.
You mentioned sharing some information before they asked for bank details. What type of information was it? Please don’t post the actual documents, account numbers, or other personal details here. That will help us suggest the right protective steps.
