There is a huge delay in Send/Receive on IMAP; Updating of IMAP Folders

I keep on refreshing but even after 10mins, the mail doesn’t download;

Even if I have read my mail on eMClient, it is is still unread on server
Even if I have changed IMAP Folders for particular mail on eMClient, it is still on the old folder at server…

Happening since last 10-15 days

I am having the same problem – seems to be gmail, especially.  It’s always perpetually sync and churning on gmail folders, even though only 1 or 2 out of a few hundred have changed.

You did not say which email provider Vinay. Who is it and which version of eM Client?

Any errors? You will find those in Menu > Tools > Operations, then in the Log tab.
