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
