Get-MailboxFolderStatistics for mailbox with items larger than 25MB

Question

Hi all,
try to get mailboxfolderstatistic for all mailboxes that contains items larger than 25 MB With the following command:
Get-mailbox -Resultsize Unlimited | get-mailboxfolderstatistics -includeanalysis -FolderScope All
 {Size -gt '25MB'}| Select-Object name,itemsinfolder,TopSubject,TopSubjectSize,topsubjectCount,topsubjectPath | export-csv c:\25mb.csv
But i get Error :
The input Object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its Properties do not match any of rhte parameters that take pipline input.
Any ideas?Im not so good at pws.
thanks!

Answer 1

Hi all,
have tried all above command but when i did a check it didnt work that well.What i ended up with is following script:
$MBX = Get-Mailbox –resultsize unlimited
$MBX | foreach {New-MailboxExportRequest -Mailbox $_.Identity -ContentFilter {Size -gt '25MB'} -FilePath ('\\server01\pst\ ‘ + $_.Alias + '(' + $_.DisplayName + ').PST')}
Downside with this script is that it export all mailboxes to a pst file.Inside its structure of users folder.
Upside is that it only export mail items that are larger than 25 MB,but you will need to create a search folder to find  items larger than 25mb.
Most of pst files that are exported are less than 2mb in size.So we sorted them by size and delete everything that is less than 25MB.
We then ended up with all mailboxes that have items larger than 25MB.
So if you have over 5000 mailboxes then this wont be recomended.We had over 1200 and the export went fine over night.
Amits recomendation also probably works,but havent tested that one.
THanks all for your help!
