Error opening Microsoft Excel or Word "The document was saved successfully, but Excel cannot re-open it because of a sharing violation."

Products

• Carbon Black Cloud Endpoint Standard (formerly Cb Defense)

Issue/Introduction

The user can successfully save a MS Excel or Word file to a mapped drive. However when they next try to open a co-authored saved file this error occurs:

The document was saved successfully, but Excel cannot re-open it because of a sharing violation. Please close the document and try to open it again

Environment

• Carbon Black Cloud Windows Sensor: 3.9.x - 4.0.1.1428 (4.0 MR1)
• Carbon Black Cloud Server: All versions
• Microsoft Office Excel: All versions
• Microsoft Office Word: All versions
• Google Drive: All versions

Resolution

Workaround:

1) Use UNC path to access file, instead of mapping network to drive-letter
2) Open Excel first and then access the file, rather than double clicking the file itself.

This is currently being tracked under EA-23784/DSEN-27167 and is scheduled to be fixed with the 4.0 MR2 release.
