Trend Micro has received some reports of a potential sharing violation issue on OfficeScan (OSCE) XG SP1 Critical Patch 5338, Apex One (on premise) as well as Apex One as a Service when a user tries to save Microsoft Office files (e.g. xlsx, docx) on a network shared (i.e. SMB) path.
This issue has been reported to be triggered when the following criteria are met:
- One of the specific products/versions above are installed and Predictive Machine Learning (PML) is enabled on the endpoint which has network shared folder; and,
- When other users try to save MS Office files to the shared folder, it will sometimes return a sharing violation error.
For Apex One On-Premise, get the latest critical patch from the Trend Micro Download Center. As for Apex One as a Service, this issue has been addressed in the June maintenance.
