Emails do not download. Last network operation failed.

Imap login is successful but emails do not download. Last network operation failed.

In my application log, it has hundreds of exception related to network operation failed.

2019-10-03 04:19:30,571 FolderName: Inbox, Message: Last network operation failed.

2019-10-03 02:54:47,133 FolderName: [Gmail]/All Mail, Message: Last network operation failed.

Please let me know why does it happen and how do I prevent this to happen and successfully download emails.

Thanks.

Those log entries are not from Mail.dll.

Most likely you were expectantly disconnected from the server.
Mail.dll throws an exception in such case. I assume you caught the exception, ignored it and tried to perform more operations. Thus you get "Last network operation failed." error.

When you get a network error you need to dispose Imap class, create new instance and reconnect.
