'Invalid email address entered, please enter a valid email address.'

How to resolve this message, which appears when you enter multiple email addresses into a Sage 50 Accounts field.

You can't enter multiple email addresses into a single email field due to Go Cardless integration, which requires one email address per field.

As a workaround, use the Email 2 and 3 fields to enter additional email addresses, then amend your invoice layout to pick these up.

Workaround

1. Select the document you want to amend, then click Edit.
2. In Report Designer, on the menu bar click Report, then click Email Settings.
3. Click the To: box.
4. Under Expressions that define the people you want to send the report to, click Add.
5. Enter SALES_LEDGER.E_MAIL2 then click OK.
6. Repeat steps 4 and 5, adding SALES_LEDGER.E_MAIL3 then click OK. 
    NOTE: If you use v29, add up to SALES_LEDGER.E_MAIL6.  
7. On the menu bar click File, click Save As, enter a new file name then click Save.
