When we send a reply on a plain text mail and insert with Outlook a smiley (like :-), which is converted to an image) then the whole mail is scrambled.
When I look at the header of the mail (in Sent Items) it is set to:
Content-Type: text/plain; charset="utf-8"
This is only happening when using the Kerio Outlook Offline connector. The version of Outlook is 1708 (Build 8431.2153), part of Office 365 Business. We tried to reproduce this problem with Kerio version 9.2.1 and with 9.2.5 patch 3 (3336) and succeed.

-On the Left, Choose "Mail"
-In the right, choose the "Spelling and Autocorrect" button
-Choose the "Autocorrect Options" button on the right in the new pop-up
- In the "Autocorrect tab" scroll down until you see the smileys.... Click on each of these and click delete, it looks like 13 smileys are there.
