Outlook.com IDLE problem

Question

I see a problem with IDLE:
When we implement imap.Idle() command for an outlook email provider, Mail.dll generates repeatedly a message:

Limilabs.Client.IMAP.ImapResponseException: Required space character missing.

This error happens only with Outlook.com. The rest of providers are fine.

Answer 1

This is the server generated error, and this is not a problem with Mail.dll.

Outlook.com doesn't support IDLE, and returns such error when IDLE command is issued by the client:

Mail.dll:  5 15:47:29 C: 79d343c7877147cb IDLE
Mail.dll:  5 15:47:29 S: 79d343c7877147cb BAD Required space character missing.

This error message, send by Outlook.com, is misleading and incorrect of course.

They should respond with "command not supported" error instead.
