I have a few basic rules on an InfoPath2010 form. I'm setting a flag value, sending data using main connection and close the form. It works fine for me and for generally all people in my company. Hovewer, sometimes is doesn't work. Such as a few minutes ago someone added an e-mail as attachment but form did not close and workflow did not trigger. Another one did the same thing and it worked for her fine. What can I do? What is the problem? I don't know how to solve it. Does attachment format affect the rules? I guess .msg document formats affects rules badly. Does anybody know anything about this?
Edit: I solved my problem. It was because of extra "." on attachment name. Now I know that MyMail..msg doesnt work but MyMail.msg works. The problem is ".." but why? Does SharePoint check attachment name and extension? How can I stop this?
