new-mailboxexportrequest -contentfilter

Hello there,

I am planning to do a migration for exchange between two forests using export/import PST files.

I would lile to export the data up to a certain date then i will do another export for delta after the cutover.

i am trying to understand the content filter siwtch and i am getting a weird behavior that i would like to understand.

i am trying the below two export commands and this just for testing and i am expecting to get after running the first one all emails sent after 2 DEC 12 AM and i am expecting to get after running the second command all the emails recived after 2 DEC 12 AM however i am getting the same output for both commands including the emails sent and received after 2 DEC  which is very ODD, i am pasting the below commands and your help is appreciated:

New-MailboxExportRequest -Name exc01-2DEC-sent1.2 -Mailbox exc01 -ContentFilter "{(sent -gt '12/2/2023') }" -FilePath \\localhost\DD\EXC01-2DEC-sent1.2.PST

New-MailboxExportRequest -Name exc01-2DEC-received1.1 -Mailbox exc01 -ContentFilter "{(Received -gt '12/2/2023') }" -FilePath \\localhost\DD\EXC01-2DEC-received1.1.PST

for both commands i am getting a PST file of the same size and after the import i see emails in inbox and sent folder for the same date.

both exchange servers are 2019 with latest CU and latest SU..
