When I am inviting a user to my account, I receive an error message "email already exists" and I am not able to proceed with the invitation. What can I do?
The reason for this odd behavior is an older registration. Before v1.6 the email alias has been interpreted as case sensitve. A user who has registered "My.Name@mycompany.com" would not be similiar to a user "firstname.lastname@example.org".
TrustSource will try to create the user, if it does not exist so far. Since v1.6 all addresses are always stored in small letters. But since the former accounts have been created differently, this leads to an irritation that the address already exists under the new conditions but the matching is not identical.
To overcome this situation, please use the correct spelling with capital letters where appropriate. Registrations since v1.6 will not run into this issue.
