''caberryman [[#question-1044192|said]]'' <blockquote> I have always copied and pasted e-mail addresses from an excel file into the "to" field on the e-mail. This has always worked fine. Now for some reason, if there is a blank row on the excel field between e-mail addresses, when copying over it is now adding commas to the e-mail addresses meaning that the address fails. Something must have changed in my settings but I do not know where. Appreciate any help please </blockquote> Just to add some info, it works just as bad if you copy from your own address-book. If there is a missing line it will show up as an extra comma and the recipient after that comma will fail.
