I have a VM with Exchange 2010 on it. 30 GB of RAM and HDD space is fine. Right now, it is sitting at 28.6GB of RAM being used. We have a big environment and soon going to Office365.
Regardless, I have about two to three users where their inbox won't update unless they tell it to do so automatically. This is a new issue. One user's inbox would not update unless we said "Update Folder." Not sure if I need to delete the OST on their desktop and setup their profile again? Exchange issue? We are running in Cached mode, too.
