Encountered a sharing violation error message

[Anonymous]

Our office has been getting error messages stating "Encountered a sharing  violation" followed by "File not Saved" when trying to synchronize. It is happening on multiple computers and multiple projects.  After a few attempts to synchronize it usually saves, but we have not had this problem in the past.  I have read some blogs that suggest that it is a firewall problem, but our IT company said they have not changed anything.  Any ideas on how to solve this problem?

Same has happened at my firm. Haven't been able to figure out the cause yet.  If you find anything out, please post any thoughts you may have.

The message shows the temp folder is accessed by other applications, maybe anti-virus software, which blocking Revit to access it. It makes the sync failed.

We have been having the same issue as well.  Started about a month ago.  Numerous users, different projects, different platforms, every day.  We disabled the anti-virus and firewall restrictions and still have the same issues.  We have contacted Autodesk and have not received any direction yet.

This does not fix the issue.

I have been talking with the Autodesk Support and our IT company trying to get to the bottom of this. They believe the problem is coming from a silent update from the antivirus software we use (Trend Micro). They said that they have been having an increase in complaints about sharing violation errors. Autodesk suggested that we add an exception list to our antivirus:

While it did not completely fix the problem, it does seem to have helped with the frequency of the error messages.  I am still working on finding a better solution and will keep you updated.

I came across an article that had another potential fix to the sharing violation errors this morning. I had our IT company modify the Behaviour Monitoring settings in our Trend Micro this afternoon. So far so good with no sharing violations - I am really hoping this is the final piece: Exceptions list + Behaviour Monitoring modifications.
