Hi StR
Thanks for your reply.
I checked it out, and there are two fields in question which would make sense to pick to display.
The first one being "Anzeigen als", which you do understand correctly, it means "display as".
The second one would be "Speichern unter", which translates to "Save as".
However, it seems like either Aqua Mail doesn't synchronize these two fields at all or they are not picked to display a contact, I did some testing, see screenshot "Outlook.png". I put the company's name in both fields (save as and display as), made sure it was synced first, but the company is still displayed with the email address from behind (meaning when the email address is info[at]campuslan.de it is displayed as "de, info@campuslan").
By the way, just for your interest, desktop Outlook (2013) works the following way with regard to displaying contacts, according to my tests: If something is written in the "name" field, it uses that. If there is nothing, like in my example, it does not use the "display as" field as would be expected, but the "save as" field.
