  • 0x800cc801 error on imap4svc after store re-mount

    Hi,

    An Exchange 2003 server reached the 75GB cap and dismounted. After remounting the store I'm getting the following error when adding a new Outlook profile:

    "An encrypted connection to your mail servers is not available"

    on the server I get:

    "Unexpected error condition: call to function CEncryptCtx::CheckServerCert() resulted in error code 0x800cc801." (IMAP4SVC)

    I checked the cert on IIS & I can connect via https. Any ideas before attempting to reboot the server?

    thanks!

    Why are you using IMAP with Outlook?
    IMAP should be one of the last protocols of choice (just above POP3) and only used if MAPI and RPC over HTTPS is not available.

    Dismounting the store should have no effect on the operation of IMAP anyway, as they are unrelated other than both being part of Exchange.

    Simon.

      Could it be because the account I'm trying to add belongs to another user that it couldn't detect to use Exchange as first option and hence the errors trying to use IMAP?

      If I choose "Manually configure server settings..." and then "Microsoft Exchange" it does the trick.

      thanks for your reply

        If you are using IMAP then the account that you are logged in to doesn't matter because it authenticates separately. MAPI does matter and requires that the account you are logging in with does have permissions to the mailbox as MAPI uses the domain for security, not individual username and password combinations.
