If you have a lot of calendar items and/or a large sync date range, I'm not surprised at all - it's having to drag all your calendar items across over the network from the Exchange server every time it syncs. Cached mode is the only sensible option really...
My reading of your logs is that you have a lot of recurring meetings that go back several years, starting in 2019 for example. These often have lots of "exceptions" where an occurrence has been changed and due to the way the Outlook model works, these all have to be retrieved to work out if they should be synced and/or have changed.
As you are not in cached mode, these have to be downloaded each time and it's taking ages. Can you not just turn on cached Exchange mode?
