To help narrow down the cause, could you please provide a few additional details:
- Are you using a business email (e.g., @companyname.com)? Or is it a personal email type (@hotmail, @gmail, @outlook.com).
- When you click the + button in Teams, do you see the option to attach a file?
- Are you attaching file in a chat with an external user?
This will help us better understand the context and provide more targeted support. Any additional information will help us better understand and support you.
Thank you for your patience and cooperation. Your satisfaction is very important to us, and we’ll make sure this is handled as quickly as possible.
I'm looking forward to your reply.

Thank you for your prompt response.Based on your information, to clear Teams cache on your Mac, I would recommend taking the following steps:
- If Teams is still running, right-click the Teams icon in the dock, and then select Quit or press Command-Q.
- In the Finder, open the /Applications/Utilities folder, and then double-click Terminal.
- Enter the following commands, and press Return after each command:
- rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams
- rm -rf ~/Library/Containers/com.microsoft.teams2
If the issue still persists, I recommend contacting your IT administrator. They can investigate the issue more thoroughly or submit a support request through the Microsoft 365 Admin Center for further assistance.
