IMAP: A connection to the server cannot be established



I have Outlook 2007 Installed on Two Separate PCs. One has Vista installed,
and the other, Windows 7.

McAfee Security Center is the Anti-Virus software unstalled on both PCs.

I have setup 2 IMAP Accounts on each PC and can only get the ones on the
Vista Box to work correctly.

This is the error I keep getting on the Windows 7 Box:

Task 'Synchronizing subscribed folders for [my-email-account].' reported
error (0x800CCC0E) : 'Outlook cannot synchronize subscribed folders for
[my-email-account]. Error: Cannot connect to the server. If you continue to
receive this message, contact your server administrator or Internet service
provider (ISP).'

Please note I have received this error on the Vista Box, but only once, and
it has been running for over 2 days, synchronizing every 10 minutes.

Whereas, the Windows 7 Box has probably only performed a send/receive once
or twice without failing to synchronize.

Also, when Outlook tells me that it has failed to synchronize, a bubble pops
up from my taskbar with this message:

A connection to the server cannot be established.
[my-email-server] is now in offline mode.

Yet if I check the "File" > "Work Offline" setting in the menu bar, it is
not set.

Can Anyone help?

Turn off email integration in mcafee - its not necessary and can cause
connection problems.

Triple check your account settings and port numbers. Can you receive but not
send or are you not getting any message in or out?

Do you sync your mailbox with a smartphone or pda?

You did not mention which version of the McAfee Security Center is installed. Some
versions does not turn off the email scanning when you deselect it. The best way and
the surest way to make sure that the email scanning gets turned off is to uninstall
the McAfee Security Center and then re-install it without selecting the email
integration (scanning) option.
