I have a user that used the Send Link by Email function within IE for years without issue. We recently upgraded the user from Office 2010 and IE 9 to Office 2013 and IE 10. This update caused IE to hang when she used the Send Link function. It wouldn't hang until she hit send in Outlook and Outlook wouldn't hang at all. The email would go through, but IE would hang and need to be restarted/killed through Task Manager. I am running Win8.1 while she is on 7, and the function works fine for me, but I don't think that is the issue.
There is nothing showing up in Event Viewer that would tip me off to a solution. I checked and unchecked Cached Exchange Mode and this changed nothing. She is up to date with her updates for Windows and Office. I updated her to IE 11 in case IE 10 was causing the issue, as I can use the Send Link by Email function fine with Office 2013/IE 11.
The thing that is odd is when Outlook is started in safe mode (outlook.exe /safe), everything works perfectly. I checked her add-ins against my add-ins and they are the same; again, I am able to use the Send Link as Email function with no issue.
Are there any other troubleshooting steps that I am missing?
