This usually means exactly what it says, “Not enough storage is available to process this command”, Outlook does not have enough storage space, and since EIOBoard logs to the disk, EIOBoard throws this error. Please check with your network administrator to see if you have limited disk quota or double check your local disk size. You could also turn off logging from EIOBoard’s settings or the registry but you will probably have other issues outside of EIOBoard so it is better to solve the root of the problem.
