Opening recent files from a SharePoint 2019 environment with Office apps is giving the following message:
Going into the Office trust center and adding the SharePoint 2019 site to the trusted host, the file can be opened. Is this the fix or is this just a temporary fix? Noticed that files in SharePoint Online, there is no issue opening the recent file from the Office app. What is different in authenticating the user to the on-prem SharePoint 2019 which causes this? Would this also cause issues authenticating opening and saving files from/to the SharePoint 2019 environment? Users are having occasional issues when files cannot be opened or saved with login windows flashing several times and access denied.
