Exchange email 'drop-out' on MS SBS Server 2003 with SP2

Hi all,

A client has an old MS SBS Server 2003 with SP2. They'll be upgrading soon (Server 2013) but have just had an issue with their exchange emails... as in, their emails aren't coming through.

This happened 30mins ago and also happened last Friday when it was down for roughly 3 hours before it seems to kick back to life of its own accord.

As I personally have very little experience with Exchange directly, at least from a setup/ maintenance point-of-view (most of our clients use Zimbra), I'm hoping you might be able to assist with the following queries:

1/ In MS SBS Server 2003, how can I find out what is causing this issue whereby they aren't receiving email. I can post more info on the problem if you can direct me to any logs which may be helpful.

2/ After Friday, they haven't received any emails which came in over that 3 hour period. Would these emails be stored in Exchange and, if so, where and how can I cause them to flow through to the end user.

In both instances, on Friday and now, the internet connection is very stable (I can easily RDP into the server to check the situation, in fact I'm in there right now).

Happy to offer up any further info if what I've offered above is patchy - just let me know what you need.

Does this only affect incoming email or both incoming and outgoing?
Did you check the transport logs?

Run the mail test through "" to check your mail flow working or not and find out what is reason mail flow not working.

ve3ofa, it affects both incoming and outgoing.

sushil84, not sure what I should be entering and where...


The exchange server is up and running now. The issue was that the drive housing the MS Exchange data was low on space - there was < 5MB left. I didn't pick this up originally because:

a) I didn't exactly know what I was looking for; &
b) I subsequently didn't realise that another drive on the server was housing this info.

One question, though, which has my baffled...:

The previous drive housing the exchange data (with low space) is a 500GB drive but would not allow us to expand that partition past its existing 320GB. We cloned proportionally onto a 2TB drive, so why does Windows SBS Server Disk Manager show that the new drive is EXACTLY the same with the 320GB/ 167GB split? This is still the case after a system reboot and is NOT the case when the drive is viewed on any other machine (not talking domain machines (didn't check those, to be honest). only on our testing machines) and also through Acronis.

To clarify my above post, the organisation is only small (20 seats) and, as such, only has a single server hosting exchange and everything else. Sorry for mentioning this only now.

when you clone a drive it is an exact replica
you could go into diskmgmt.msc and expand the drive to then use the available space.

OOPS, you need a 3rd party partitioning tool since MS SBS Server 2003 is out of date and doesn't have the expand / shrink options.

Sorry guys, in a bit of a mental fog today.

So, the proportional drive clone was completely successful - I believed I was cloning their D: but actually cloned their C: (which is fine - it could do with more space). I can use Acronis to expand the remaining partition to include the previously excluded 167.67GB of unallocated space, so I reckon we're all good now.

Thanks for your help!

Solution was nothing more than increasing the space on the drive as it hadn't been immediately obvious this was the resolution to the issue.

Once space freed and server rebooted, emails started to flow.
