I am experiencing an issue with Sharepoint through Office 365 and a mapped drive to the content.  When the mapped drive is first added, the drive stays connected for about a week.  After then the connection is lost.  When clicking on the mapped drive I get an error message web client network access denied (attached picture).  I have added the site to the trusted sites before mapping it initially and I know the mapped drive does work.  The only way I was able to fix this without remapping the drive every week is to open sharepoint on the web, browse to folders, and open in explorer.  Once I open the local folder of sharepoint, the mapped drive connection is restored.  Any ideas?

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.

All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

Office Productivity refers both to the act of being productive and efficient in an office or professional environment, as well as the software applications used to "produce" information. This includes the development of professional skills, creating work processes, and almost any program used to create or modify a document, image, audio or video clip. However, business application suites such as Microsoft Office, which include word processing, spreadsheet and presentation programs, are typically called productivity software, as contrasted with a "utility program," such as a file manager, which is used to organize files and folders on the computer. Many office- and business-oriented groups of programs are organized into suites.
