We have a issue with some emails, and its very strange. We receive an email from someone outside our organization and it changes to draft. The mails in question are sendt to a mailbox where several users have access.
First we upgraded our exchange server to 2013. Then we upgraded some of the outlook clients from 2010 to the 2013 version. Still there are no change. I have searched the web and some people say its is a problem regarding antivirus, but we uninstalled the antivirus on a client but the problem still exist.
Now, is there any other ways to go about this problem?
