Multi Tabbed FreeBusy/OOF Board

In the past I've posted scripts for a Free-Busy Board and an OOF Board which uses the EWS Managed API and PowerShell. The following is a combination of the two that displays the OOFStatus of the user combined with their FreeBusy and Calendar Appointments in a Tabbed based output eg

To build the list of Mailboxes to create the Tabs the script uses a Distribution list and the ExpandDL operation which will retrieve a collection of SMTP address's for the members of the group. It then uses the GetUserAvailblity operation and MailTips operation to build the output.

To run the script you need to use the SMTPAddress of mailbox you want the script to run as and the SMTPAddress of the Distribution list to expand. eg

fbooftabs.ps1 user@domain.com dl@domain.com

I've put a download of this script here the code itself looks like

How to test SMTP using Opportunistic TLS with Powershell and grab the public certificate a SMTP server is using

Most email services these day employ Opportunistic TLS when trying to send Messages which means that wherever possible the Messages will be encrypted rather then the plain text legacy of SMTP. This method was defined in RFC 3207 "SMTP Service Extension for Secure SMTP over Transport Layer Security" and there's a quite a good explanation of Opportunistic TLS on Wikipedia https://en.wikipedia.org/wiki/Opportunistic_TLS . This is used for both Server to Server (eg MTA to MTA) and Client to server (Eg a Message client like Outlook which acts as a MSA) the later being generally Authenticated. Basically it allows you to have a normal plain text SMTP conversation that is then upgraded to TLS using the STARTTLS verb. Not all servers will support this verb so if its not supported then a message is just sent as Plain text. TLS relies on PKI certificates and the administrative issue s that come around certificate management like expired certificates which is why ...
