Hello @LeonK36 we're sorry to see you're having some difficulties downloading your contacts from Outlook into a CSV file. Here are the steps to download your contacts into a spreadsheet from Outlook Express:
Once your file is full of contacts, run through it to make sure that it's formatted correctly to prevent any import errors, and that your contact headings match the standard headings used in Constant Contact, before you upload it. If you have column headings that you want to keep but don't match the standard headings, you can create a custom field to capture them during the import process.
I would also like to add that If you have contacts stored in Outlook Express, export them into a CSV file so you can import them into Constant Contact; however, contacts must be stored in the Top Level Address Book folder. Outlook Express will not export contacts in sub-groups due to a known Outlook Express issue.
Please let us know if you are still experiencing any difficulties exporting your contacts into a CSV file!
