Recently, I discovered an issue when accessing SharePoint site with SharePoint Designer.
The SharePoint site is published through UAG.
I’m able to open and browse the site with SharePoint Designer but I’m unable to save some work, such as publish workflow (even standard one or not modified) or upload some files.
I always have the following error:
The server could not complete your request. For more specific information, click the Details button.
And the Details button doesn’t provide any additional details.
I’m investigating.
