The VPOP3 Status Monitor is the program which shows the little (usually red) postbox icon in the Windows task tray. This usually launches automatically from the Windows startup group. This program is VPOP3Status.EXE on the disk, or can be run manually from Start → Programs → VPOP3 → VPOP3 Monitor in Windows.
The status monitor talks to VPOP3 using TCP/IP, usually using port 5109, and it has to log into VPOP3 as a user, so different users can be configured to access different features through the status monitor. Therefore, you should be able to the status monitor from any computer on your network.
If you have multiple status monitor icons in the task tray, this does not mean that VPOP3 is running several times, just that the VPOP3 Status Monitor has been started several times. Sometimes this can happen if it has been added to the 'All Users' Startup group as well as your personal Startup group in Windows.
How you remove the duplicate icon depends on the version of Windows you are using.
In Windows 7, press the Start button, go to All Programs, then find the Startup group. Right-click it and choose 'Explore All Users'. This will show the list of startup items in the 'All Users' group, rather than your personal group. Remove the VPOP3 Monitor shortcut from there.
If the status monitor is not showing all the data you'd expect, then it is probable that the status monitor is logging in as a user without permissions to see that data. To correct this, choose Disconnect from VPOP3 Server then Configure Status Monitor and check which user it is logging in as. Then edit that user in the VPOP3 settings, go that user's Permissions tab and check that the Remote Status Server Permissions section contains the desired options.
If the VPOP3 status monitor is unable to connect to VPOP3:
You may find that the VPOP3 status monitor is double-correcting for the time zone difference. For instance, if your local time zone is UTC+2, then you may find that the status monitor is displaying times as UTC+4. Alternatively, you may find that the status monitor is not correcting for the time zone difference at all, and is only showing times in UTC.
This happens because you have the incorrect version of the VPOP3 status monitor on your PC. You should use the status monitor software from the VPOP3 installation (usually stored in the main VPOP3 installation directory as VPOP3STATUS.EXE).
The VPOP3 installer will update the status monitor version on the VPOP3 PC itself, but it will not automatically update it if it has been copied to any other PCs.
In older versions of VPOP3, VPOP3 itself would correct for the time zone to send times to the status monitor in VPOP3's local time, which the status monitor would simply display as-is - this caused issues for multinational installations where the status monitor was not in the same time zone as VPOP3 itself. Therefore, in the current versions of VPOP3, VPOP3 sends the times in UTC, and the status monitor corrects the time into its local time.
So, if you have a current VPOP3, and an old status monitor, then VPOP3 will send the time in UTC, and the status monitor will not correct it. Alternatively, if you have an old VPOP3, and a current status monitor, then VPOP3 will correct to the local time zone, and the status monitor will also “correct” to the local time zone, meaning that a double correction occurs.
