Important emails should be saved to an employee folder. 2. Electronic documents like PDFs can be kept for a maximum of 8 years but may be destroyed when no longer needed. Word, Excel and PowerPoint files may be deleted yearly. 3. Webpages must be retained for 5 years as required by regulations, and then archived for an additional 3 years by the IT department.
