The ESA panel will be inaccessible during the maintenance, but email delivery will not be affected in any way.
The update is being carried out to update the panel to the latest release.
Our Services engineers will remain onsite till the panel is back up and fully operational before closing off the maintenance.
If you experience any issues accessing or using the ESA panel following this work, please call our Helpdesk on 0345 1435 1234 and we will be happy to investigate.
