When replying to or forwarding an email with attachments this is the response I get:

You can only have 5 attachments. Please remove some files and try again.

This happens when just replying and also forwarding an email with attachments, never had this problem before. 

I've read a few post on here saying the same and they have had their accounts changed to allow the sending of more than five attachments. Could mine be changed please?
