Hi there,
since we upgraded to Dynamics 365 v9.0 on-premise we are experiencing problems when sending email campaigns to contacts that only have private addresses (email2). I found only one person who had the same problem (https://www.crmug.com/crmug/communities/community-home/digestviewer/viewthread?GroupId=1285&MessageKey=c8d49b4b-27ea-4ee1-bf7c-18d45722b06e&CommunityKey=dc83c23b-ede0-4070-ae7a-dd90859148a6&tab=digestviewer) so I wonder whether this is rather a problem of configuration than a systematic bug.
Any ideas?
Kind regards
Lucas
