Contacts: add a new contact > click button "Edit Email Addresses" > add more than 4 emails (e. g. 6) > OK > Synchronize
Evolution > Select the contact > edit some information (e. g. "Mailing Address") > OK > Synchronize
Actual: After synchronizing only 4 emails are available in Contacts.
Target: All 6 emails must be available, information must not get lost.
If there are more than 4 email addresses stored in the kolab contact, only 4 will be mapped to vCard and the rest will be precerved in hidden fields.
It works in v0.0.7. I close the bug.
