how to move calendar items that are more than a year old to archive?

Hi @gihyun Park ,

Thanks for posting in our Q&A forum.

It seems impossible from server side.

From client side, it is suggested that you can export your calendar items to a .pst file and then import them to your archive folder.

And a source explains how you can use the AutoArchive feature in Outlook to move items from your active folders to an archive folder. Please refer to: https://support.microsoft.com/en-us/office/autoarchive-settings-explained-444bd6aa-06d0-4d8f-9d84-903163439114

I'm not clear how to implement by EWS.

$service.Bind($mailboxId)


$items = $service.FindItems($calendarFolderId, "CreatedDate lt '2023-08-25'")


foreach ($item in $items) {
  $item.MoveToArchive($mailboxId)
}

$service.Close()

This will help to solve your problem.
