Hi EE,

I have a remote user who is using offline files and redirected file and folders. I noticed some sync errors in windows 7 sync manager and found that the machine is trying to sync archive.pst.tmp file from the server to the machine. Now, this file only exists on the server and not on the laptop. I cannot move or delete that tmp file.

Any ideas?

.pst files can't by sync'd and will generate errors like that.  You will probably need to turn offline files off on that directory before you will be able to move or delete that file.  Why it has a .tmp extension also I don't know.

This worked in XP, not sure about Windows 7.....

reg add "hkcu\Software\Microsoft\Windows\CurrentVersion\NetCache\ExclusionErrorSuppressionList" /v ".tmp" /t reg_dword /d 0x1 /f
reg add "hkcu\Software\Microsoft\Windows\CurrentVersion\NetCache\ExclusionErrorSuppressionList" /v ".pst" /t reg_dword /d 0x1 /f

Just prevented the error from mobsync from showing that it couldn't sync.....

Need to find out what has an open handle on the .pst.tmp file so it can be deleted...

Search for it in Process Explorer on the Server/Workstation.....

Then you know what to terminate to free it.....

I stopped the sync of the PSTs and TMP files and moved them to a different location. Also the TMP could not be deleted, however managed to move the folder to a different folder and delete that way. Before when tried deleting the files just reappeared again within seconds.
