Hi, what version of eM Client are you currently using and what mail service are you using?
Can you download and install this update and check if it solves the issue?

Thank you,
Paul.
I already got the latest version. But I can upload a screen shot of the window I’m talking about:

Hi what version of eM Client are you currently using then, can you tell me the exact version number from Help > About?
Also what mail service are you using?
Thank you,
Paul.
Ok I only tried to check for updates in the client itself… After this answer of you I checked the Help>About and it wasnt the same as you wrote above… installed the client from your link and no more problems! Thanks for your nice and fast support!! I’ll recommend your e-mail client to my friends and family
Great, glad that i helped, let us know if you come across any other issues, or questions, we’ll be happy to help.
Thank you,
Paul.
