Office Document Conversion

< Back

On May 1st 2016, We added the file extensions for Microsoft Office 1997 thru 2003 to our Attachment Filter list. These files include, but may not be limited to. *.doc, *.xls, *.ppt. Our mail servers will no longer be able to send and receive these Office file types due to a rise in emails with malicious attachments. Below are three methods to convert your Office 97-2003 files (*.doc, *.xls) to the Office 2007 and newer format (*.docx, *.xlsx). You may also Print or Export your documents to a PDF file.

  1. With the Document open. Click on File. (Note that the Window title states [Compatibility Mode] next to the File Name.)
  2. Click on Convert
  3. Click on OK (Optionally you may check the “Do not ask me again about converting documents” check box)
  4. Finally Save your file. Office will replace the .doc version of the file with a .docx version
  5. Send the converted file in your email.
