powershell scripts to identify the number of users using outlook in online and cached mode

Hello Experts.

Is there a PowerShell script or utility that can be used to identify and export all mailboxes using outlook in cached mode and online mode?

In addition to request above, is there a PowerShell script that can be used to force all users in a spreadsheet to use outlook in cached mode, and or switch from online to cached mode?

I did follow steps from link below but the list of users returned appears not to be accurate


I did check the spreadsheet returned for a few users that were on classic or online mode, and check user's outlook configuration and it was on cached mode. The same users have IPhones, devices using active sync, I wonder if users with active sync devices will show as they are connected to MBX and CAS servers using online mode?
This should be a question related to AD. I would not go into looking for the exchange logs. It should be a setting at the client level.
By default outlook goes into cached mode. Create a AD group policy such that users cannot change the mode from cached to online.
For users who need to be in online mode, Create a security group called OutlookOnlineMode. Create a Group policy which puts users in online mode. Apply this group policy to this group. add the users to this group.

If you have a separate AD admin, they should be able to handle this case easily. And it will be a full time solution.
