dear All, 
i am facing this Problem now and looking for some help Really i need it , 
Please if you know a solution or if you know recommendation , Please Help me . 
i am working on it Now. otherwise no need to see or her some comments which is 
not good at all . Please Help me in this . 
i have big Problem in My exchange server .
i have one server which installed on it SBS2000 with Exchange 2000 and ISA2000.
and as you are a ware this SBS2000 comes with Bulit in Toll for download Emails 
from POP 3 Server , and this Toll called POP3 Connector. 
but i found that i have a Problem with it .
 i found this Error message in Front of me :-
Microsoft Connector for POP3 Mailboxes has encountered an internal error that 
it could not recover from. 
After you close the error message dialog box, the following files are created: 
?C:\Program Files\Microsoft BackOffice\Connectivity\POP3 
Connector\Vmimb.txt?C:\Program Files\Microsoft BackOffice\Connectivity\POP3 

i searched on the internet and i found a sloution for it . 

but this solution tell me  the following :-
========================================CAUSEThis problem may occur if the 
following conditions exist: ?The Microsoft Connector for POP3 is in the process 
of downloading a lot of messages.?
The next-scheduled connector download time occurs.

The time that it takes to download the larger volume of messages is exceeding 
the scheduled download interval. This interval is set in the Microsoft POP3 
Connector properties. This situation causes a conflict with the current 
download of inbound messages and the scheduled start of the connector. 
WORKAROUNDTo work around this problem, increase the Microsoft Connector for 
POP3 Mailboxes Scheduler time. This provides a longer interval of time before 
the next start of the connector. The next-scheduled start of the Connector 
occurs later, and does not overlap the current download. 
Start the Small Business Server (SBS) Administrator Console, and expand the 
Exchange node for your organization. 

Expand the Administrative Group, the first administrative group, and then 
expand the Connectors node. Right-click the Microsoft Connector for POP3 
Mailboxes, then click Properties.

2.On the Connect and Download tab, click the Schedule button.3.Change the 
scheduled settings to increase the existing interval between each scheduled 
download. Zero hours and fifteen minutes are the minimum intervals for the 

NOTE: The exact location of the Microsoft Connector for POP3 Mailboxes may 
vary, depending on the options you selected in the Exchange node properties, 
Administrative Views.


as you can see i understand the following :-

The Time that POP3 Connector takes to download the large Volumes of Messages is 
exceeding the sceduled download interval .

it means that , the pop 3 was busy in download Large messages and took more 
than 15 Minutes, then while it was downloading , it found that the 15 minutes 
finished and it should start again or should connect again , then this 
situation or this conflict has been done , is that correct ? 

so, the solution which was recommende from Microsoft was to increase the time 
of Microsoft Connector for POP3 Mailboxes Scheduler time.

its by default 15 Minutes, But if i make if for Example 30 Minutes, it means 
that, i am telling Microsoft Connector for POP3 Mailboxes to connect to the 
POP3 server every 30 minutes and download the E-mails.

but what will happen if was there a lof of E-mails and the connector take more 
than 30 minutes and the Next Schedlue start. i think i will face the same 
Problem agian , and also all of my users will be un able to recevies E-mails in 
matter of 3 minutes, but they will face a problem that if they send messages 
and some one replyon it , they will never see the Reply except after 30 minutes 

is there any solution for that Problem ? 

Please Reply as soon as Possible .
