Only pdf files are valid enclosure file formats for Communications. The valid enclosure file types need to include Outlook messages (msg). Also other valid enclosures should include Word (DOC, DOCX),Excel (XLS, XLSX) as well as images (PNG).
I am voting for this as we have a communications process we are currently working through, and they need a payroll format (in Excel) loaded with the communication that goes out. Currently, only PDF is available to add as an enclosure (unless a user adds it manually every time). Would like to have this considered for Excel (.xls and .xlsx) and other formats.
