Description: File generated by Microsoft Exchange email programs such as Outlook; appears as an email attachment for email clients that don't recognize Microsoft's proprietary TNEF format; may cause the text "application/ms-tnef" to appear in the email if the email client does not recognize Microsoft Exchange formatting.; A DOTM file is a Word Open XML Macro-Enabled Document Template used by Microsoft Word, part of the Microsoft Office suite. It is a template file that contains default layouts and settings for a document, including macros, which are small programs that automate repetitive tasks. Unlike standard Word templates (.dotx), which do not support macros, DOTM files enable users to include custom macros that can be executed within the document. This feature is particularly useful for creating standardized documents that require specific automated functions.
