Can you unsubscribe from subfolders? If so, does doing so stop the mad
crawl? Perhaps there is a folder, or more likely a message in a folder,
that the Outlook client doesn't like - and it is then restarting its
'sync' over and over.
Are Exchange extensions disabled? I've seen them cause various kinds of
Tools -> Options -> Other -> Advanced -> Options -> Add-In Manager ->
Uncheck Exchange Extensions property.
Tools / Options / Other / Advanced Options / COM Add-Ins/ remove
anything that isnt essential, (we remove everything)
Those may not correspond to your version of Outlook.
Although it may make matters much worse [temporarily] you might want to
turn on telemetry for that user to see if there is a protocol error
But clients just walking folders shouldn't generally drive massive
syslog traffic; perhaps you are logging mail at the DEBUG level? Don't
do that, it is better to use telemetry logs selectively.
