There is an update regarding MFA Multi Factor Authentication. If you are guest with a different Tenant, the MFA Settings are now reflecting the settings of all tenants in a different way. Each MFA setting is reflected and you can setup your MFA device as per tenant and the admin settings allow. Login to your Profile in Office 365/ Azure AD: https://account.activedirectory.windowsazure.com/r/#/profile or https://myapps.microsoft.com Go to your PROFILE: Sign in to https://myapps.microsoft.com Select your account name in the top right, then select profile.

Cannot join external Lync Meeting: Lync Edge Server Single IP Address (Lync Edge Server Single IP Web Conferenceing Problem)
Lync Edge Server FQDN and IP PORTS (Version 1.2, Update 26.11.2014) As we all know, we can configure Lync Edge Server in several way. 1) Single Edge Server with a SINGLE IP ADDRESS 2) Single Edge Server with MULTIPLE IP ADDRESSES (3x IPs) 3) Multiple Edge Server in a Pool, with MULTIPLE IP ADDRESSES (Zx 3 IPs) Regardless what we are going to configure, there are common / well-known TCP Port necessary making Lync work, which are: Access: Port: 443 and 5061 Conferencing: Port: 443 and (444) AV: Port: 443 (I have not listed other ports, e.g. STUN or the dynamic port range. This is not required for the topic discussed here) External FQDN with single IP address: What can we see here? If we are going to choose a single IP address, we would have TCP Port overlapping.

Very often you find in Lync/ Exchange deployments an issue, where the Lync configuration show up with empty: EWS Internal URL EWS External URL and EWS Information = EWS not deployed Therefor Exchange Web Service are not connected deployed and several Lync Integration Features are not working, e.g. Presence Information based on your Outlook Calendar.
