(Solved) WVD [Spring Release] Outlook Web App Redirection

Recently I created an app pool in order to web app the Outlook client. I used a gallery image (using Win10 1909 Multi w O365) I created and deployed 5 hosts with this v1 image and published the app without issue. When using Outlook and creating a new email you could attach a document from the local machine's C: drive.

I made an update to the gallery image and redeployed new hosts in their place with the updated image. When I redeployed my updated hosts with the v2 image, I lost the redirection when using the Outlook web app.

I have also created a separate desktop pool with a different image and am experiencing similar issues all of a sudden, no drive redirection. This is using the same gallery image that I simply installed a few apps on and published to SIG.

I reviewed the custom RDP properties doc and confirmed settings via PS as well as via the host pool > properties > RDP settings UI - https://docs.microsoft.com/en-us/azure/virtual-desktop/customize-rdp-properties

PS results: 

PS C:\Program Files\PowerShell\7> Get-AzWvdHostPool -ResourceGroupName <RESOURCEGROUP1> -Name <HOST1> | format-list Name, CustomRdpProperty

Name : <HOST1>
CustomRdpProperty : audiocapturemode:i:0;audiomode:i:0;drivestoredirect:s:*;redirectclipboard:i:1;redirectcomports:i:0;redirectprinters:i:1;redirectsmartcards:i:1;screen mode id:i:2;

Am I missing something here to enable redirection to access the local machine's drive? I have made minimal registry or GPO changes in the image, nothing that would impact redirection to my knowledge. I am using the Spring release of WVD as well.

Thank you for any assistance!
