I want to find messages with the exact subject "eFax Report", not subjects containing the word "eFax Report".  I've tried all of the following search querys and get the same results which include subjects such as "FW: eFax Report", "Aug eFax Report", ect. 

Any ideas?

Search-Mailbox -SearchQuery {Subject="eFax Report"}
Search-Mailbox -SearchQuery {Subject:"eFax Report"}
Search-Mailbox -SearchQuery 'Subject="eFax Report"'
Search-Mailbox -SearchQuery 'Subject:"eFax Report"'

You can try

Get-Mailbox Server Server Name | Search-Mailbox -SearchQuery 'Subject:"Your bank statement"' -TargetMailbox "DiscoveryMailbox" -TargetFolder "Search Items" -LogLevel Full 

And you can also use New-MailboxExportRequest

Have you tried the query's submitted.  I've tried and it does not return the exact subject but the word(s) contained in subjects searched.  I'm sure anyone can verify.  Can anyone confirm?

Hi,

Refer to this document and take a look at the detailed explanation of Example 2&3, this query will return the messages that contain the phrase in the subject.
