Thanks for looking at this problem. I have one user on Microsoft Office 2013 Home & Business on Windows 7 Pro x64 that is having a problem with Excel crashing. The are in a spreadsheet and want to send it as an email attachment. They go to File --> Share --> Email --> Send as Attachment. I allows them to put in the recipient, subject, etc, but when they click Send it crashes Excel. They get the "Excel has stopped working" error. Here's what I have done so far:
Offline repair (Online repair tells me I have no internet connection)
Creating a new profile in Outlook and deleting the old one
I have noticed that it only seems to do this when Outlook is open. If I try it with Outlook closed I can get them to go through fine. It is hit and miss when it crashes, but probably 50% of the time.
