How to solve email format problems

Use commas to solve email format frustration

QUESTION When I try to send an email I get the error: ‘Message not sent. Please check all email addresses. Looks like one of them may not be formatted correctly'.

I can send an answer by pressing reply, but not otherwise. I have already checked that all the addresses in my contacts list are correct. J Knox

HELPROOM ANSWER It's hard to diagnose the exact cause without knowing which email client you're using. However, it's possible that some email addresses have had their fields filled in incorrectly.

Some programs are stricter about formatting than others - Outlook prefers semi-colons between addresses, for instance, while Thunderbird insists on commas.

Some users have reported similar problems in Windows Mail, resulting from a corrupt contacts store. If you're using this free program, try switching to its successor, Windows Live Mail.
