Why am I getting REGEX errors when creating/updating contact e-mails via API Operations?

Environment:

B2C API 

B2C Email 

Issue:

Getting REGEX e-mail errors when creating/updating contacts via API operations.

Resolution:

Email address validation is handled by regular expressions configured within the Oracle B2C Service product. Email addresses much match a regex pattern to be allowed. 

The regex the product uses is: ^((([-_!#$%&'*+/=?^~`{|}\w]+(\.[.]?[-_!#$%&'*+/=?^~`{|}\w]+)*)|("[^"]+"))@[0-9A-Za-z]+([\-]+[0-9A-Za-z]+)*(\.[0-9A-Za-z]+([\-]+[0-9A-Za-z]+)*)+[; ]*)$

If you have any problems with a valid email d address that does not match that string, please contact the Oracle Support team by submitted a service request.
