  • you can try 

    ased on my research, you could refer to the folllowing ways.

    1.Open Windows Explorer and navigate to the location of the XLSForm file.

    2.Right-click the name of the file > Properties.

    3.From the General tab, view the bottom of the popup where the Security information is listed.

    Here, the following message is displayed:

    Security: This file came from another computer and might be blocked to help protect this computer.

    If the file source is a trusted, safe location, click Unblock.

    Click Apply and click OK.

    repeat the process of creating the form from Teams.

  • Hi RDSH,

    Does everyone have this problem?

    Is this problem just on a certain document?

    There are five methods to edit/open/download this document. You could try them one by one.

    Agree with Lakshmanan Sethu, you could Unblock the Security of the document in Properties have a try.

  • Hi all,

    Thank you very much. All users have the same problem and this will be very annoying if I need to unblock every file. Is there a way to turn off this check? 

    Lakshmanan Sethu what do you mean by repeat the process of creating the form from Teams. Do you mean that I can create some form to auto unblock the files?
