Error ID 13007 from MS pop3 interface

[remain]

I've been getting a "Error ID 13007 from MS POP3 interface"
with a category: "Configuration" very often recently. At first I was only getting it for one or two people who had unique setups on their outlooks, now I'm getting it about 5 times a second every couple hours for a group of about 20 users.

The error text is: "A server error (0x8004010f) occurred when processing Outlook Web Access Url for mailbox <long name of mailbox>" the other common server error is: 0x80070005.

The users are not using OWA when this error occurs.

The original two had both MS Exchange Server set up (so that they could use the calendar features only) and POP3 to download mail. We have pop3 set up for all of the other users.
This error doesn't seem to effect anything system side or client side, but I would like to know what this error is, since it is occurring so regularly...plus if it is causing some sort of minor damage I'd like to have that repaired. Thanks in advace,

I've searched everything from Microsoft and they don't even seem to want to acknowledge that this error is possible, let alone provide a way of getting rid of it. I haven't found anything else via google or any other kind of search like that either. if someone could please provide some advice it would be much appreciated,

Thanks

Does anyone know ANYWHERE else I can look for information on crappy uninformative errors that microsoft dishes out but doesn't document?

Thanks
