Incoming mail in Outlook 2013 shows senders from automated mailing with additional information since a month or so.
See this article: https://docs.microsoft.com/en-us/answers/questions/ask.html
I do not see any option to display the names / addresses without these additional fields.
What could be the cause of this? And the solution?
Via the webmail I see the sender address without the extra fields.
Two examples:
FROM: return-to@<domainname> on behalf of <name newsletter> [newsletter@<domaniname>
FROM: bounce.x.y@mailing.<domainname> on behalf of <name newsletter> [newsletter@<domaniname>
