MM 4.0 Outlook Client - Service Provider Error

[definityandcmuk]

Hi all

When I try to add a new email account I enter the hostname, mailbox number and password and then get

Access Denied. Use a telephone or the web client to access mailbox. The mail system's privacy settings prevent you from accessing your mailbox using MS-Outlook Client Add-in.

I've tested all the mail settings on the MSS, if I telnet to the mss on port 143 I get OK IMAP4 server ready.

Is this error coming from the MSS or could there be something on the exchange server that blocks the access?

Thanks in advance

I found it, for anyone else who may run into this, in the COS there is a "restrict client access" field which was set to n.
