You are working with 2 conflicting requirements. Using erooms and share resource pools – don’t work. The links between the MS Project files are exact disk locations. You are right – erooms is using virtual and web locations which doesn’t work for resource pools.
You might have to let management know that you have a software restriction that will not allow you to do both – they have to pick one or the other.
Have a nice holiday – I am about to leave on 2 months on the road for work – I think you will have more fun. Best of luck to you.
