I'm running the following query; Get-Mailbox -ResultSize Unlimited | where { $_.Identity -eq 'contoso/BOB'} | Export-Mailbox -AllContentKeywords "keywords"-TargetFolder bobquery -TargetMailbox 'Herman Ballmer' -BadItemLimit 10000 -confirm:$false The issue I'm running into is when the allcontentkeywords has several entries(over 30) the results come back empty(nothing in the folders no emails). If I run the query with say 6-8 entries the results come back with emails in the folders. Is there a limit to how many keywords can be searched? Thanks, D

Did you used the switch -ContentKeywords ? The buffer for the AllContentKeywords parameter is 32 kilobytes. That may be the issue.Regards from www.windowsadmin.info

Hi, Will -ContentKeywords also have a buffer limit? Thanks, D

Hi d42d01, First,ManU's advice is good. The buffer for the AllContentKeywords parameter is 32 kilobytes. When the allcontentkeywords has over 30 entries,may be the buffer for the AllContentKeywords parameter is over 32 kilobytes. Thanks, Jeff TechNet
