Citrix roaming profiles cannot be deleted due to roaming Windows Error Reporting folders locked by Symantec Endpoint Protection (SEP) 14 MP2.
SEP was improperly leaving Windows Error Reporting handles open. This locked the folder which prevented the profile deletion.
This issue is fixed in Symantec Endpoint Protection manager 14.0.1.0 (RU1) For information on how to obtain the latest build of Symantec Endpoint Protection, see Download the latest version of Symantec Endpoint Protection
