Exchange 2007/2010/2013, List deleted items in each Mailbox

Exchange 2007/2010/2013. Before a migration there is a discussion of the "Deleted Items" in Outlook.exe and IF those/should get migrated. We found out that often people use the Deleted Folder as kind of Archive if there is no commercial Archive solution in place (5% with 1000+ boxes). Also users have really strange sorting method. One person said that she first deletes all email and then PICKS the important and moves them to a subfolder.

So before you choose the GPO option "Delete all Deletes on Exit" maybe check with some larger users in advance.

Moven Mailbox overnight, watching "Deletes Items" pass… For sure there are migrations scripts which migrate a few en block automatic if you are interested.

Here is how to list the Deleted Items from each mailbox you have and export into a file:

get-mailbox -resultsize unlimited |

get-mailboxfolderstatistics -folderscope deleteditems |

select identity,itemsinfolder |

export-csv d:\edv\DeletedItemCounts.csv -notype

get-mailbox -resultsize unlimited | get-mailboxfolderstatistics -folderscope deleteditems | select identity,itemsinfolder | export-csv d:\edv\DeletedItemCounts.csv –notype
