It seems that you can never have too many ways of reading the number of Unread messages in a Inbox so here is another method. The following script uses two AQS queries to work out first the number of messages in the Inbox from a prescribed period eg the last 30 days and then the number of these that are then unread. It then works out the percentage of unread using of the two values and then creates a graph to display in the Console using Alt-ASCII characters which produces a pretty nifty output eg
![]()
It also produces a CSV output eg
![]()
AQS queries will work in Exchange 2010 and 2013 so this script should work okay in those environments as well as ExchangeOnline.
I've created two versions of this script, the first version just reports on one user so you run it with the email of the users you want to report on and the number of days to query back. eg
.\AQSUsr.ps1 gscales1@msgdevelop.onmicrosoft.com 30
the second version reports on all of the users in a CSV file and uses EWS Impersonation to access the Mailboxes. To use the script you need to have configured EWS Impersonation and feed the script a CSV file of the users you want to report on eg the CSV file should look like
smtpaddress
user1@domain.com
user2@domain.com
and you run it like
.\AQSAllUsr.ps1 ./users.csv 30
I've put a download of both scripts here the code look like
