Hello
I am a first time user, and after importing contact i saw a cloumn i did not need. The Contact ID column. Little did i know so I deleted it. Now when updating my list with more contacts I can’t update the existing list because of the missing column.
Please help. How do I readd the column.?
Kind regards Klaus
Hi @klauselmfelt,
When you say that you deleted a column, was that a column under Menu > Contacts > Contacts? If you removed a column by clicking Table actions > Edit columns, that was just a cosmetic change in the UI. You can re-add it the exact same way. This cosmetic change has nothing to do with the import process.
If you the import file from your screenshot is a new file, you can safely uncheck the “Update existig” tickbox. HubSpot will still check if there are contacts in your CRM already which have the same email address as the ones you’re about to upload. If yes, HubSpot will update these contacts.
However, if you want HubSpot to update your contacts not based on the email address (as unique identifier) but based on the Contact ID, you would check that box. Since your import file doesn’t have this Contact ID, you’re getting an error message – but that’s not a problem, because, again, HubSpot will just use the default: the email address.
To simplify things, if you’re just starting with HubSpot and you haven’t exported any contacts from HubSpot which you’re now importing again, uncheck the box and you’re all set.
Best regards!
Hi Karsten Köhler.
Thank you. 
Not checking update exsisting did the trick.
