Use PowerShell to Export a List of My Sites

How many My Sites (MySites) are currently enabled in my Farm?

if(-not(Get-PSSnapin | where { $_.Name -eq "Microsoft.SharePoint.PowerShell"}))
      Add-PSSnapin Microsoft.SharePoint.PowerShell;

$site = Get-SPsite ""
$spWebApp = $site.WebApplication

$log = "c:\test.txt"

foreach($site in $spWebApp.Sites)
    $site.url |	Out-File $log -Append

load the powershell snapin.
get the Web App hosting your My Sites.
set a variable to where you want the script to output the results to.
loop through all the sites in the Web App, and output them to your text file.

My Site Emails Not Sending

In SharePoint 2010 I noticed I wasn’t receiving updates when people posted stuff on my MySite.

Turns out, my Active Directory Sync is not working, and my email account was not being populated in my User Profile.

Fix it!

Central Administration –> Manage User Profiles
Find the person having the issue.
Update the email address.
Cruise over to the mysite, post a note, look in your inbox for an email.
