Is it possible to require Multi-factor Authentication (MFA) be enabled for specific/all IAM accounts in Amazon Web Services?
There are options for password requirements and it's clear how one can choose to add it to one's account, but it's not clear if there is an option to force users to have MFA.
We're planning a roll-out of MS Lync without the telephony, for at least the time being. The presence indicators in Outlook and SharePoint include links to call telephone numbers (Call Home..., Call Work..., Call Mobile...) in addition to the voice chat (Call Name). Invoking the first set will fail since we are not integrated with the phone system.
Note: These links are only appearing in the presence indicator, not in the Lync client itself.
Is there any way to disable/remove the links for the telephone numbers, while keeping the links for the voice chat?
I am currently experiencing an issue sending email to one specific domain. We are running Exchange 2007 (recently migrated from 2003). We are able to successfully send email both internally and externally to any other domain. The emails are queued in a DnsConnectorDelivery type queue with no Last Error message.The server is able to resolve the MX record correctly. The SMTPSend Log reveals the following:
2009-10-21T06:37:47.265Z,SMTP to Internet,08CC201AD304F254,0,,x.x.x.x:25,*,,attempting to connect

...with x.x.x.x and y.y.y.y being the correct first and second MX records for the domain.
From my desktop (but a different external IP address), I am able to Telnet into x.x.x.x:25 and y.y.y.y:25 and send an email. When attempting to Telnet from the exchange server, it just waits after issuing the 'OPEN x.x.x.x 25' command. I am able to Telnet to other SMTP servers from our Exchange server successfully.
I'm working with and admin on the other domain to determine if our IP is somehow blacklisted, but is there anything else that would cause these symptoms?
