This email is in use - choose another email

[Anonymous]

Hi I keep getting the error "This email is in use - choose another email" - for two new users I want to add - both of whom defintiely are not in the system. I tested it with another fake email address and worked fine - any ideas?!

Thanks

Hi James, chances are the emails are being used in another Marketo instance, perhaps they were in an instance with another company?

I've had the same issue a few times in both Marketo and Salesforce and that seems to always be the answer.

Thanks Lucas - I doubt it though as the email address used is for our company. No other possible reason?!

Please log a support case.  We'll investigate

Ok way to do it if future people see this:

They had a salesforce insight email plug in license, and you can't have that then add them as a user for some reason. 

So I've had to revoke the outlook license, wait a few minutes, then add as a user, then add another outlook license
