Assigning full access permission to backup service account failing..

Thanks Alan,

I was checking same thing for my script too which pulls all the users in the organization. For assigning full permission your suggested solutions worked.

Below is the script, i'm using to pull all the mailbox users and export into PST.

get-mailbox -resultsize unlimited -erroraction silentlycontinue | Get-MailboxStatistics | select-object *,@{name="TotalItemSizeinMB";expression={[math]::Round($_.totalitemsize.value.ToBytes() / 1MB,2)}},@{name="TotalDeletedItemSizeinMB";expression={[math]::Round($_.totaldeleteditemsize.value.ToBytes() / 1MB,2)}},@{name="CombinedTotalSizeinMB";expression={[math]::Round($_.totalitemsize.value.ToBytes() / 1MB,2) + [math]::Round($_.totaldeleteditemsize.value.ToBytes() / 1MB,2)}},@{name=“SourceDatabase”;expression={$_.Database}} | sort-object combinedtotalsizeinMB -Descending | select displayname, *GUID*, *MB,ItemCount, DeletedItemCount, LastLogonTime,SourceDatabase | export-csv -force -notype C:\Temp\test.csv

Bit hard to read, but is that all one line / command?  If so, well played Sir!

Without pulling it apart and trying it myself, if you want to just export all the mailboxes, there are easier (shorter!) ways, but if it works, it works :-)

Alan.
