Since the roll out of Internet Explorer 10, our users were having trouble whenever they attempted to give someone access to their SharePoint 2010 area via the Grant Permissions dialog. Whenever they clicked the Browse icon, they’d receive a “An unexpected error has occurred” message.
One solution that seemed to solve this issue was to add the domain of the SharePoint site into the browser’s Compatibility View Settings – but that would effect all sites using the domain (including non-SharePoint sites).
While researching the issue I found a suggestion that it could be corrected by appending a META tag to one of the MasterPages.
Normally I wouldn’t dare edit one of the SharePoint core files, but as this was effecting so many users and we’ll be migrating to SharePoint 2013 in the near future, the benefits outweighed the risks.
- Browse to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS and locate the pickerdialog.master file.
- Immediately after the opening HEAD tag, insert the following line: <meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE8″ />
The changes appear to have resolved the issue completely.
