Hi,

When I came back from my vacation, the mail on my company didn't work.
We have the domain and mailserver on one.com, then we use the pop3 connector to recieve it from one.com to our sbs2008 server.

It worked perfectly for a year, but now all of a sudden it does'nt.
I've tryed to restart all the services, even the server it self, but it didn't help.
It still sync our calender and the internal mail to our phones. And I can send mail, BUT it won't recieve mail from outside.

I don't even know where to begin to look.

Some help would really be appreciated.

Check the server for disk space and make sure there is enough.  If the logs fill up the drive it will stop mail flow.

It looks like you have discovered the 'Backpressure' "feature" of Exchange.  Please have a read of my article and check your event logs, and if any event ID's in my article are mentioned, apply the quick fix, then clean up your server:

I will read your article

You can actually be right. c:/ on the server have only 8 GB free diskspace out of 230GB

If it is a space issue then following Alan's article will allow you to mount the stores.

Once you have done this you can quickly flush the logs by enabling circular logging as per: http://technet.microsoft.com/en-us/library/bb331968(EXCHG.80).aspx

This will flush all the logs and get you back up and running pretty quickly.

Just remember to disable circular logging when finished and take a full backup of the Exchange store.

But I can't find what on the C:/ disk that take that much space. I checked the properties on each folder, and none of them are that large..

It worked! Thanks alot!

BUT, I enabled cirk logging, but it didn't delete any files. I still only have 7 GB free disk space. Where can I find the files, and can I delete them manual?

Thanks
I can't find the files that take all this space

Circular logging isn't a good idea to enable unless you immediately backup the Exchange Server.  If you enable Circular Logging and then have a crash, you will lose data.

To make it work, you have to enable it and then restart the Microsoft Information Store Service.

Are you not running backups of the server?  If you were - then Exchange logs would be purged if the backup software is Exchange Aware, which the SBS Backup program is.

I'm running the SBS backup tool that is intergrated in the OS. Last backup was running yesterday, but it didn't purge the log files. Can I locate and delete them manually?

No - don't delete them manually.  Is the backup completing properly?

Did you use the SBS Backup Wizard to configure the backup?

Author

Commented:
Yes, in the SBS console/Backup, it says completed succesful.

Yes, I used SBS backup wizard

Are the logs recent ones?

Under what directory can I fins the logs, so I can check if it is the most recent ones?

As you can see I'm a little new to exchange..

Can't recall the default location (I always change it by default).  Look for e00*.log files.

Some useful reading for you:

Interesting reading. But it didn't solve the problem. I also tried to search for e00*.log files, but couldn't find any of these.

The disk space still decrease. I really need to purge the log files somehow..

Thanks

I've checked every folder on the server, but can't find what files that are so large..

Author

Commented:
Free disk space: 4GB now.. It decreases..

I don't know what do to, but I guess i'll have to configure a new backup, and see if that helps. If it will purge the log files, I can't find..

Try the following software to show up what is in your server:

Great program.

It showed me where all the large log files are.

They are here, in this folder: C:\inetpub\logs\LogFiles\W3SVC1931480611

Is it safe to just remove them?

Yes - unless you plan on reading them because of a problem.

I did mention this in my earlier comment days ago:

You need to work out which logs those are by looking in IIS - my guess is the WSUS logs, which you can disable logging for as you don't want 60gb of log files filling your disk up!!
