When a CIFS shared Directory Path is disabled or deleted from Data Domain, it takes some time to be reflected in StoragePoint. StoragePoint can continue externalizing, recalling or migrating content during this period of time. Testing indicated the average time to reflect a deny message to the endpoint is from 10 to 20 minutes. After this time, the correct access denied messages will be shown in the logs.
To prevent lost data, add a second endpoint to the profile, move content of the DataDomain share by bulk migration timer job, then remove the DataDomain endpoint from the profile.
