I  have been happily using the send immediately option when emailing payslips for the last 6 months approx.  However when doing it yesterday only about 5 sent immediately and the rest I got an error message stating recipient address unknown and they went into my drafts and I had to individually click on each one to send.  I tried Sage Support but they weren't very helpful (first time ever I have to say). 

Has anyone else had this problem?  We had to run some Window updates on Friday so maybe it was because of that?

Any help would be greatly appreciated.
