Outlook 2013 crashes when doing a reply all

[utickite98]

Using Outlook 2013 when I get an email that the sender has sent to several email addresses, I write my reply and click reply all. When I do this a message appears that Outlook has stopped responding and is looking for a solution. I usually click cancel and Outlook has closed. I open it again and check the email that I was replying to and it shows that I replied to the message. Does anyone have any ideas as to why this is happening?
