I've googled on this to no avail so am hoping that someone else here may have seen this.  

In checking my network traffic connections just now I came across a situation where a workstation at one of our remote sites is connecting to the server across port 38870 via the application MAPI-PREOP.  I'm not finding much information online about this port and am concerned that I may have a possible security issue.  The workstation is XP pro SP2 with the latest updates and McAfee virus catalog.   The server is SBS 2003, also with the latest updates.  

Please advise.   I could just block this port to see what breaks but would prefer to know in advance what it might impact.

Ok, in looking into it further one of our WAN Accellelleration devices creates this as a Mapi caching item so that users can load their email faster.   I'll request to have the question closed.
