Re: Advisory Memorandum - Internet Explorer v. 7.0

The Commonwealth Chief Technology Officer is issuing this Advisory Memorandum in response to questions raised about version level support for Internet Explorer (IE) in agency desktop configurations. Please be advised that ITD has not, as of yet, performed formal or rigorous testing of IE7 or IE8. However, based on current industry practices, Commonwealth agency feedback, and business owner feedback, it is advised that agencies that use Internet Explorer upgrade to IE7 or higher.

In evaluating which version will best fit your business needs, please take into consideration the following points.

Enterprise Systems:

  • MMARS is supported for IE7 and IE8
    • IE8 will be required with the next release of MMARS
    • Some users have reported some unexpected behavior
  • HRCMS supported for IE7 but not IE8 as of its upgrade in March 2010.
  • Mass.Gov is supported for IE7 and IE8
  • Teamsite/CMA supports IE7 but not IE8 as of yet
    • Some users have reported some unexpected behavior
  • DocDirect/ViewDirect supports IE7 but not IE8 as of yet
  • Clarity/Service Desk (E2E) has conducted successful preliminary tests results with IE7
  • Outlook Web Access (OWA) has no known issues with either IE7 or IE8

Upgrading and maintaining the latest IE security patches or MS recommended mitigations will offer better security as some anti-malware capabilities have been improved in the newer releases. In addition, support for lower versions of IE is being phased out. At this time, it is recommended that agencies upgrade to IE7 or higher, if you have not already done so. Please keep in mind that agency's will also need to test their internal applications in order to select the best version. It is also recommended that agencies begin requiring their applications operate correctly with at least two web browsers (e.g.: IE7 and FireFox3) in an effort to ensure standards-based applications and meet the preferences of employees, partners, and citizens.
