Project Web Access 2010 Manage Timesheets and IE 11 Compatibility


Version: 1.0


I came across a scenario where a user needed to recall and delete some of his Project Web Access (PWA) 2010 timesheets. Its not straightforward, keep reading :). The user was using Internet Explorer (IE) 11 on Windows 7 running under VMware VDI.

Normally a user would click on ‘Manage Timesheets‘ from PWA to delete / recall timesheets. With IE 11 the user was getting error:

This Project Server 2010 feature requires at least Microsoft Internet Explorer 7.0.

Looking at the official Project Web Access 2010 Support page, I noticed that IE 11 is not supported browser for by Microsoft Project Web Access (PWA).

The way to go with IE 11 with Project Web Access 2010

Solution 1:

Add your PWA URL * in the local intranet zone of Internet Explorer.

Besides that review the Compatibility View Settings under Tools menu. The default compatibility view settings display the local intranet sites in Compatibility View.

The above method has few benefits:
a. user will not be prompted with the login to PWA site on local intranet
b. Compatibility view default settings will make the PWA URL to work in compatibility mode

Solution 2:
If adding sites to IE Local Intranet zone is locked down by IT, then review the Compatibility View settings and make sure Local Intranet sites option is checked (above screenshot). If it is not than check it or just add the url into the field above and click Add

Solution 3:
If IE Local Intranet zone and Compatibility View settings are locked down by IT, then your next option is to use IE Developer Tool using F12 key and changing Document Mode and User Agent settings.

Solution 4:
There are few other tricks but I’ll not cover those details here for the sake of time. Those are around manipulating the user agent & x-ua Compatible settings.

Solution 5:
Roll out Local Intranet Sites and Compatibility view settings via Active Directory Group Policy (GPO) settings.

Alternatively for a Virtual Desktop Infrastructure (VDI), Remote Desktop / Terminal Server or Citrix type environments, make the configuration as part of the global / admin change that all users in that virtual environment will automatically get.
