Hi there, I have used Exchange 2007 for quite some years, but I am trying to switch to Sogo, Openchange and so on. The most of my install works fine, except for one tiny culprit. I cant use Outlook 2007 or 2010 with "old" users.I have used Outlook 2013 to create and import all mails (5 mailboxes), they are syncing fine with iOS, Windows Phone, Android, SOGO Webmail, Windows 10 Mailapp and Outlook 2013. Therefore I wanted to Switch the testserver with Exchange 2007, but: If I am trying to connect Outlook 2007 to one of these accounts I get an Samba backtrace (and Outlook closes, doesnt sync anything). If I create a new user (samba-tool user add test && openchange_newuser --create test) I can use Outlook 2007. Therefore I think my install should be OK, but somehow populated Mailboxes with Outlook 2007 are not.Does anyone has an idea? I am out of ideas.
