Need expertise from a Powershell guru

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can run it once every month. That's what you are looking I guess. I don't see anything scripted to run every week. It is the way you use it and collect the data.

Hi Amit,

I am not following you,

Are you saying that script above can be run per month, and will show the information requested?

If not,

Do you have a PowerShell script that can be used for this purpose? the information presented on the final spreadsheet must be based per month
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Correct, the script just reports the current standing. You can run it as often as you want. It will not report a delta, only absolute values.

Hi Qlemo,

Since the script above returns all users in Exchange, is there a way to modify this code, and return only a few mailboxes given a CSV input file?
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Sure. You'll have to replace the first code line, which gets the mailboxes to process. I'll assume no CSV file but a text file with only the (alias) name on each line, no title.
$listOfMbxs = Get-Content C:\Scripts\ListOfMbxs.txt
$mbxs = Get-Mailbox -ResultSize Unlimited -Filter {RecipientTypeDetails -ne "DiscoveryMailbox"} |
  Where {$_.Alias -notlike "extest_*"} |
  Where ($listOfMbxs -notcontains $_.Alias} |
  Select Identity, PrimarySmtpAddress, EmailAddresses, EmailAddressPolicyEnabled, OrganizationalUnit, UseDatabaseQuotaDefaults, ProhibitSendQuota, ProhibitSendReceiveQuota, IssueWarningQuota, Database

Hi Qlemo,

Regarding the stats reports, are the totals for the lifetime of the inboxes or is there a specific start date?
AmitIT ArchitectCommented:

Sorry, I was away, saw this today. Are you clear, what I am trying to say or you still have doubt.
Jerry SeinfieldAuthor Commented:
no, I need a complete explanation on how this script works, and the results obtained.

Are the total for the lifetime of the inboxes or is there a specific start date?
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
The stats are just as they are at that moment - for the lifetime of each acount until now. Such stats cannot be retrieved (directly) for only a week or month or day or whatever, Exchange is not keeping track of that, and so we cannot ask for it.
