get-mailboxdatabase -resultsize? - 24.Jan.2012 6:33:25 AM

When working with an exchange environment with a large number of mailboxes, you can set -resultsize unlimited with the get-mailbox cmdlet. The same option is not available with get-mailboxdatabase, so the query is limited to the first 1000:

"WARNING: By default only the first 1000 items are returned. To change the number of items returned, specify the parameter "-ResultSize". To return all items specify "-ResultSize Unlimited" (Note: Returning all items may take a very long time and consume a large amount of memory depending on the actual number of items). It is not recommended to store the results in a variable; instead pipe the results to another task or script to perform batch changes."

But "-ResultSize Unlimited" does not work with this cmdlet. Is there another method used with get-mailboxdatabase?

Many Thanks

Steve

how about:
get-mailboxdatabase | get-mailboxstatistics | Sort-Object TotalItemSize -Descending | ft DisplayName, {$_.TotalItemSize.Value.ToMB()}

I get 2830 results without error. Perhaps i have set the "modify the maximum number of recipients to display" to 10000 in the Exchange Management Console. Maybe does this help?

Do you have over 1000 databases? That's the only reason I would see to have to set a -resultsize on that particular powershell command.

However, it would make more sense if you were trying to return all mailboxes on a particular database, such as, get-mailboxdatabase -identity dbname | get-mailbox -resultsize Unlimited
