@Ajay,

1. Not all servers report such changes.
2. After IDLE returns you can perform any operation, including Flag.Unseen search. You can also download most important email information for 100 most recent emails: http://www.limilabs.com/blog/get-email-information-from-imap-fast
3. You can also examine Imap.CurrentFolder property. It contains properties such as Expunge, Recent, MessageCount

For getting new emails, I am just searching mails with UID greater than last sync everytime I get response from IMAP.IDLE. But How can I use IMAP IDLE to get the specific updates like message read/unread changes, deleted emails?

Regards,
Ajay

@Howard,

You can find more details on “Tried to read a line…” error here:
http://www.limilabs.com/blog/tried-to-read-a-line-only-received

Basically, it means that either server disconnected or you have had a small connection problem – which is understandable if you maintain a connection for several hours.

If you receive such error the only thing you can do is to simply reconnect.

@Saqib,

If you download the message (GetMessageByUID) usually server marks it as seen automatically.

You can also use MarkMessageSeenByUID method:

Take a look at all Mail.dll samples, most likely you’ll find the code you need there.

sir,when i access email through email.idle notification,i want also mark the email to read
can you tell me how can i do this

@Scott

You can use any folder name:

client.Select("All Mail")

In case of Gmail you may want to use CommonFolders class to get the All Mail folder name:

> Is there a way to find out which email goes with which folder in this case?
In case of Gmail you can get all labels for specified message:
