enable ping replies from Windows Server 2008

I had a Windows 2008 R2 server that would not reply to pings.  This server was not the member of a domain (it was a standalone Hyper-V host).  I fixed this by running this from an elevated command prompt:

netsh firewall set icmpsetting 8

I got this from this page:

display shared Exchange calendars on an iphone/Droid

I'm documenting a solution for display shared calendars (for example your boss's calendar) on an iphone/Droid.  I tried this via two Office365 accounts (on two different domains), and it worked well.

Links to explain the process:

In essence, you share your boss's Exchange calendar as an iCal calendar (this does require a publishing process via right clicking on the calnendar and choose Share -> Publish this calendar).  In my tests, a web link to an .ICS files was created.  Send to the employee and the iphone (in my tests) will properly interpret the link as a shared calendar and add it as a calendar in calendars.

Additional mailboxes in Outlook still appearing even after removing them account settings

In my Exchange environments, it's pretty common for me to give one user access to another user's mailbox for any number of reasons.  Sometimes, the user has left the orgaization.  If Joe has left, I'll give Bob access to Joe's mailbox in Exchange Management Console (giving Bob full access to Joe's mailbox) and then Bob will follow these steps to add Joe's mailbox:

Sometimes, I use this feature for common mailboxes like a careers@domain.com mailbox or and info@domain.com mailbox.

Recently (the last year or so as of 5/12/14), I have found that even when you remove the mailbox using from account settings (from the same method you use to add the mailbox in Outlook), the mailbox does not disappear.  An Exchange attribute needs to be changes to remove the user's mailbox.

Let's take the example of Bob opening Joe's mailbox.

Open ADSI Edit.
Drill down until you find the entry representing Joe's account.
Right click on Joe and choose Properties.
Scroll down to MSExchDelegateListLink and double click on that field
Remove Bob's account from the list.

After the steps above are done, Joe's mailbox will disappear from Bob's Outlook.
