Delay in read emails & GTalk

I really love this program because of how well it integrates Google Apps with my desktop. I have a question. Is there a reason why when going through my emails why it will lag on some of the emails to clear as read? It gets aggravating sometimes.

Also, with GTalk closing down this month, how will eM Client integrate with Hangouts?

Hi Robert, eM Client by default only downloads the headers of emails to avoid synchronizing additional content and speed up the synchronization process. The read status can automatically be synchronized once the message is downloaded by eM Client or you can force to update the read status, by marking the message as read manually.

In case you haven’t adjusted this, you can also adjust the time in which the message will be marked as read in the application settings under Tools > Settings > Mail > Read.

Hope this helps,
