Currently I'm developing RPA with UiPath to automate tasks in my internal website that requires only IE for compatibility.
And we can use only Microsoft Edge browser with set IE mode at this time, since my company doesn't allow to install IE browser from now.
Is it possible to set Never expire for IE mode on Microsoft Edge?
If you configure the enterprise mode site list using the group policy then it will never expire and could help you overcome the 30 days limit when you add the site to IE mode manually.
You could ask the IT department in your company to help you set up the group policies for the Edge browser to configure the IE mode and sitelist.
Below are the detailed steps.
I assume that you already have the latest MS Edge policy template installed. If not, you could refer to the steps from Configure Microsoft Edge policy settings on Windows.
Let us know if you have further questions or you face any difficulty configuring the IE mode. I will try to provide further suggestions.
