Pop3 Mail not being downloaded
Hi there,
My event log is littered with the following error.
An error occurred while delivering mail to 'myuser@mydomain.com' on the SMTP server 'localhost'. The error code was 0x800ccc6c. Verify that the mailbox exists and that the Exchange receive connectors are configured properly.
Mail is not being downloaded at all. I have read different reasons for this. On the basis of articles I have found, I have expanded the potential mail store file size to 60 GBs. I have also checked that the firewall isn't the cause. My connectors are all working the same as they have always done. The pop3 connector has always worked perfectly well. There have been no updates done to the server.
The pop3 log is not even possible to open as it has grown to such a huge size (GB). I have tried renaming the extension to .zip and still no joy.
Any advice would be greatly appreciated!
Dave.

The problem might be due to low disk space on the system partition.
Hi
Maybe there is an invalid message stuck in the mailbox you are retrieving from.
if you can access the pop3 box via webmail, do so and check if the offending message is there.
have you turned on diags in the pop connector?
to remove the log, stop the exchange services and then rename the log file.
ALSO, you might be running out of space on the system drive of the server.
if on sbs, wsus logs could be eating your hdd space, you can disable wsus logging.
give it a go and let us know.

There should be approximately more then 2 GB free space on the drive

Hi guys, apologies for the delay in response. I was away over the weekend.
There are no mails stopping them downloading. It happens across all users, it started working randomly over the weekend again. Very strange. I am sure it will stop again as it has happened before!
I have to install SP3, as it is not installed yet. I am hoping it may resolve the issue.
As for space, it is sitting on a drive partition with approx 400GB free. So space is not an issue.

Thanks for that Redeinterna, but no joy. Still have this issue.
Just to come back to your comment about drive partition with approx 400GB free is this also the system partition or another? because the free space should be on the system partition.
About the log file have you tried the rename the log file after stopping the windows SBS pop3 connector service?

Ronny,
The System partition has 7GB free and is 136 in total.
Yes, I did. I even made a copy of it and tried accessing it.

Still think this is the problem because everything you will find on this specific error is about disk space problems. Normaly it is a percentage of your partition size, but I cannot find anything what the percentage is. Can you clear up som space on this partition, to see if it starts working afterwards?
Does it create a new one when you start the service again maybe that one is opening a bit easier

Ronny, thanks for all your responses! Greatly appreciate your time!
I have cleared out to 18.6GB of free space on the system drive.
The log is much smaller now and I have access to it. Something I am reading, when it is falling to bring mail down from the POP3 accounts it seems like it is looking to an SMTP server?

No problem!
Can you post the log file?

To be sure this is a SBS 2008 server right?
Can you also check if there are any event errors on the system or application log?

Thank Ronny, gonna try these over the weekend!

This entire thread led to the resolution of my issues, but this post was the main part.
Ronnypot's solution worked for me: the system partition (200gb) was almost full, only 4gb free space, and SBS POP3 download stopped.
Even though the Exchange database is on a different partition with lots of free space.
Anyway, after cleaning up C: everything is OK now.
It is an SBS2011.
