Outlook New Experience update - network save location bug

Anonymous
2022-07-21T05:58:48+00:00

My default save location when saving documents from Word/Excel/Outlook is on network folder via folder redirection for Documents and Desktop. When i switch to new experience interface and try to save email attachment from Outlook it's trying to open the shared folder via port 80 instead SMB file share which cause an pop up display Connecting: Trying to connect to: \fileserver\share...

Microsoft® Outlook® for Microsoft 365 MSO (Version 2206 Build 16.0.15330.20260) 64-bit

If I manually change the default save location to point on some local folder and then navigate to the file share via "save as" dialog it browse the shared folders normally and open the network shares normally. Also if i disable the new experience switch and return to the old interface of outlook it works ok. This problem is observed only in the New experience interface for all Office products (word/excel/outlook) when the default save location is pointing to the network share.

For Word and Excel there's option for default save location

    Workaround Solution #1 worked for standard SMB file shares but did not seem to fix for DFS Shares.

    Thanks for the Workaround

    Does anyone have a workaround for DFS ?

    Thanks

    Thanks for the tip on WebClient!

    After looking into the WebClient service (i.e. WebDAV), here are the two workarounds that worked for us (see below). We wanted to avoid disabling the service outright.

    Workaround #1

    Block WebDAV/WebClient Traffic to your local SMB/file server from each client PC.

    Assumes you don't have HTTP/s services running on your local SMB/file server.

    #PowerShell

    $SMBServerIPs = @('192.168.111.111','1111:1111:1111:0000:0000:0567:5673:1111')

    New-NetFirewallRule -DisplayName "Block Outbound WebDAV (WebClient) Traffic to SMB File Server" `

    -Group "!!Troubleshooting (IT Dept)" `

    -Direction Outbound `

    -Protocol TCP `

    -RemotePort 80,443 `

    -Action Block `

    -RemoteAddress $SMBServerIPs

    Workaround #2

    Disable WebDAV/WebClient Traffic for Websites (that might be) running Sharepoint or Office Web Server.

    Potential issues with MS365 services(???).

    Set HKLM\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\AcceptOfficeAndTahoeServers to 0 (Default is 1) (https://docs.microsoft.com/en-us/iis/publish/using-webdav/using-the-webdav-redirector)

    Hope this helps someone else.
