Hi @rohit-2018 @poseidonphp ,
please take a look at these issues: #153 #100 #78.

So far it could be caused by to many things. Please try to provide some more information (code samples, call stacks, etc) in order to figure things out :)

Best regards

how can i fix: imap_open(): Couldn't open stream {outlook.office365.com:993/imap/ssl}

So far, IF you have a shared mailbox, the parameters for the user name should be something like [email protected]\sharedmailboxname like [email protected]\info.
But imap_open failed to authenticate.
The only solution I've found was to patch the getAddress() function in Client.php

        $slash = strpos($this->username,'\\');  
        if ($slash > 0) {  
            $address .= '/authuser=' . substr($this->username,0,$slash);  
            $address .= '/user=' . substr($this->username,$slash+1);  
        }  
        $address .= '}';  

==> address becomes {outlook.office.com:993/imap/ssl/[email protected]/user=info}
Of course, try first your connection parameters using either thunderbird (configure thunderbird for office and/or test your connection using openssl (manually testing imap) to be sure you don't have a problem with the mailbox or your credentials.
