Outlook IMAP Error   

I'm getting the following intermittent error when Outlook tries to 
receive mail from an IMAP server:

Task 'Checking for new mail in subscribed folders on <email address>.' 
reported error (0x8004DF0B) : 'Outlook is unable to download folder 
(null) from the IMAP e-mail server for account <email address>. Error: 
The connection to the server is unavailable.  Outlook must be online or 
connected to complete this action. If you continue to receive this 
message, contact your server administrator or Internet service provider 
(ISP).'



We are on a wired LAN, and outlook is connected when this issue occurs.

Thanks,

RE: Outlook IMAP Error   

Hello Customer,

Thank you for posting here.

According to your description, I understand that you connect the Outlook to 
a IMAP server, but intermittent get error about the IMAP connection. If I 
have misunderstood the problem, please don't hesitate to let me know.

First, please let me know that: Does the IMAP server is your internal 
Exchange server?

If the IMAP server is the external server in your ISP, this will be not a 
Exchange related issue. Please repost your issue in Outlook newsgroup for 
help. Or contact the ISP for assistance.

Outlook newsgroup: microsoft.public.outlook

If the IMAP server is your internal Exchange server, based on my research, 
I suggest we try the following steps to see if we can resolve this issue:

1. This problem occurs because the Microsoft Exchange IMAP4 service are 
turned off by default in Exchange. Please open services console on Exchange 
server and ensure the Microsoft Exchange IMAP4 service is started.

2. The unstable network connection will also cause this issue. Please try 
to ping the Exchange IP address with switch t (ping xxx.xxx.xxx.xxx -t) 
(Ctrl+C to stop) when the issue happen, to test the response time and to 
see whether there is lost package.

3. What's version of your Outlook?

4. What's version of your Exchange server?

I hope these steps will give you some help. 

Thanks and have a nice day!

Sincerely,

Terence Liu,
