check space?

check SMTP service? telnet IP address 25

Inbound or Outbound?

check event logs?

received this from wormly

Resolving hostname...
Connecting...
SMTP -> ERROR: Failed to connect to server: Connection refused (111)
Message sending failed.


applied the hotfix from the MS article. a bunch of messages went through but now the event viewer is filling up again with the 9791 errors. messages awaiting directory look up increasing.

thanks

Can you create a new SMTP Virtual Server please as this seems to have resolved other similar issues:

Alternatively, check for big emails that might be choking Exchange in your inbound queue.

Not seen this one before, so not using my grey-matter for a solution (sorry).

thanks alanhardisty. I will check it out. seems like it has chilled out and email is flowing again. I looked and there are no large emails. however, we have some users with 15 GB email accounts and we are on exchange 2003 still. anyway... thanks

15Gb - you are asking for headaches!

Hopefully the patch has helped it.

HA! indeed. the managing partner noticed the issue now it is priority for everyone to clean up. hope all that activity doesn't crash the server! anyway, I'll have to revisit moving accounts to a new store per this

http://www.experts-exchange.com/articles/Software/Server_Software/Email_Servers/Exchange/Exchange-Offline-Defrag.html

and this

http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_25856577.html

as I have only about 18 GB left on the drives but now likely over 60 GB free based on what I already had showing in 1221s on the server and what users deleted today, and over the next few days.

thanks again fellas

That's a lot of free space you can reclaim :) - Time to schedule some down-time.

just watch the crafty users do not just move to PST files on unsupported network drives, and fill your network drives up!

quick question - I am down to about 11 GB of space on my database drives. I have a ton of log files going back to 1 am this morning. Can I safely delete the E0092xxxx.log files to make some room?

thx

You should never manually delete Exchange Log Files.

An Exchange Aware Backup should take care of the log files automatically after a full backup has been performed.

Worst case scenario - enable circular logging but make sure you backup the store asap afterwards otherwise you may not be able to recover Exchange if something breaks and you need to recover.

that is what I thought, but also thought I remembered that I could delete old ones that would've already been committed. When Veeam runs tonight, it should remove those I guess (it runs an incremental though). I guess I'll just add some space to the drives on the SAN then configure the server in vCenter, then run expart to increase just in case. I don't want there to be an issue during backup of running out of space.

thx for the quick response.

No probs - getting late for me, so if it was a little later - it would have been a much slower response :)

any Exchange aware backup product will flush the logs, leaving only a few.

You could run Windows Backup, to a network share, and it would flush the logs, but your database will grow.

Best thing would be to grow the LUN,+20GB.

Funny. Ok. I tried to ask a new one but was denied due to abandoned questions. However, I took care of those earlier. Can either or both of you hook a brother up in this instance? Not sure why it is even listing this question as abandoned.

Thanks!
