What command or script can I run to search a particular mailbox for an email based on a subject? 
 
Office 365 (Exchange Online) 
 
Ive been trying : 
 
1. Search-Mailbox -Identity &quot;JohnDoe&quot; -SearchQuery 'Subject:&quot;Saturday Event&quot;' 
 
2. Get-Mailbox 'JohnDoe' | Search-Mailbox -SearchQuery 'Subject:&quot;Saturday Event&quot;' 
 
3. Get-Mailbox | Search-Mailbox -SearchQuery 'Subject:&quot;Saturday Event&quot;' -TargetMailbox &quot;JohnDoe&quot; 
 
4. Search-Mailbox -Identity &quot;JohnDoe&quot; -SearchQuery Subject:&quot;Saturday Event&quot; 
 
 
Results: 
Search-Mailbox : The term 'Search-Mailbox' is not recognized as the name of a cmdlet, function, script 
file, or operable program. Check the spelling of the name, or if a path was included, verify that the path 
is correct and try again. 
 
Here's the weirdest part, in Outlook Web App, I can search, and find the email in the deleted items. When I look in Outlook, there's nothing in the inbox. 
 
So I'm trying to locate the precise location of the email and assist the user.
