Certificate error 80048888 on Lumia 920 Windows 8 Phone

Mail from Exchange server does not sync.


I have configured a Lumia 920 to sync mail on a SBS2011/Exchange 2010. Worked fine for a while, but now I get a certificate error 80048888. I have installed a new certificate, but that makes no difference.


 I can log on to OWA and Remote Desktop from the phone.


Link to guide about installing and managing certificates on Windows 8 Phone appreciated, I have not found any - yet.


Advice needed?
