Hallo,
please help with the following problem in the eM Client program.
In the attached image, you can see a red triangle with an exclamation point next to the email account.
It happens when I move the email to the folder I created. If I move the email to the system folder (such as Trash, Junk) the triangle does not appear.
Thank you,
Best regards, Mareš Michal.
Move an email that causes this issue, then go to Menu > Operations > Log tab and see if there is an error near the end of the text which gives more information.
