If you are using Live Mesh, you may want to dig deeper into what it is really doing. To do so, I just found some interesting log files.
Mesh has a trace/activity log placed in C:\users\*\appdata\local\microsoft\live mesh\gacbase\Moe-*-*-*-YYYY-MM-DD-*.log. It seems to log quite a bit of information, so expect huge log files.
The file is a kind of CSV-file, but without headers. Luckily, Import-Csv in PowerShell V2 has a –header arguments, so you can decode the file using -
dir *.log | import-csv -header Date,Severity,Component,Number1,Number2,Number3,Message
As you can see, I have no clue as to what numbers 1 to 3 are for, but please comment, if you know.
