Office 365 Read Another Mailbox

Question

Hi,

I have an office365 account, which is the main account, but I can add sub accounts under that account. e.g my main account is ben.riches@dogoffice.co.uk I then have a sub account (hello@dogoffice.co.uk) that uses the above email address as the username and the same password, as it's just a sub account. How do I only read emails from the sub account?

Regards,

Ben

As this is rather Office365 question I'm not sure if we are able to help.

Have you tried logging as it was a completely separate account:

imap.UseBestLogin("sub-main@example.com", "password");

Are you sure this is not an email alias? I wasn't able to find any documentation on sub accounts in Office 365.

If that is a case, you can log in using your standard credentials and then perform search on To and Cc headers:

imap.UseBestLogin("main@example.com", "password");
List<long> uids = imap.Search()
    .Where(Expression.Or(
        Expression.To("sub-main@example.com"),
        Expression.Cc("sub-main@example.com")));

[Edit]

It seems you can do this using shared mailbox syntax:

imap.Login(
    "Username@DomainName\\SharedMailboxAlias", 
    "password");

Within outlook or office365 online I can login as me but then open another mailbox.

I done it this way:
imap.Login(@"Username@DomainName\SharedMailboxAlias", "password");
