I have Exchange 2007 and I have incidents that mails just got stuck inside outboxes (in plural, because several users have come across this problem). I've seen other posts talking about the same thing but the mails are actually sent already. But for me, some mails are indeed sent but some are NOT sent. This also happens when users is sending through OWA. So that might exclude a problem in Outlook. I don't expect to have an immediate solution (but I won't refuse it if it exists :) ) but I hope Microsoft is aware of this serious bug because some users thought mails are sent but actually not. My Exchange Server 2007 is at feature pack 1 or SP1. I'm not really sure. It's version is 08.01.0375.002. Is this bug corrected in SP2 or SP3?

Check your services on the Exchange server to be sure the mailbox assistance service is running. Restart it if it is and see if that helps. Then check event logs for errors as to what may be causing the issue.

You may run Exchange Best practices Analyser and see if there is error reported

Hi Horinius, Is there any warning/error events in the Event Viewer? Please also run the EXBPA in the toolbox. If you send mails in OWA, do the mails stuck in Outbox or Draft? And also suggest you install latest Service Pack. Frank Wang

Hi Horinius, Any updates?Frank Wang

Is there any warning/error events in the Event Viewer? Oh yes! Certainly, there are a lot of warning and error in the event log everyday, but 1. I clear the log almost once a week so there's not much thing left. 2. I always take a look at the errors before cleaning, and I'm pretty sure they're not in relationship to Exchange 3. Even if they aren't cleaned, since I have no idea when that really happened, this doesn't really help. Please also run the EXBPA in the toolbox. And what am I to do exactly? If you send mails in OWA, do the mails stuck in Outbox or Draft? Outbox. And also suggest you install latest Service Pack. Sure. Is there any link to any "precautions" that we should read before applying the SP? Actually, backing up mailbox database is one of the precautions and I know that. Previously I had set up another DPM server to do the backup, but for some unknown reason, that stupid piece of ____ just stopped working! And I'm still struggling to pull it back on. My Exchange server has no tape drive or any other backup means except a real big hard drive and there is a lot of free space. Could someone give some advice to do a backup in this situation?

Hi Horinius, About EXBPA, please go to Toolbox->Open "Best Practices Analyzer", choose the "Health Check". About backup, hope your OS is Windows 2003. So you can backup Exchange using NTbackup.exe. Detail information, please see: Using Backup to Back Up and Restore Exchange Data http://technet.microsoft.com/en-us/library/aa998870(EXCHG.80).aspx But if OS is Windows 2008, you can only use Windows Server Backup if you install Exchange 2007 sp2 or later. Please also backup AD data.Frank Wang

Best practices analyzer, I have: (red cross) Database backup critical: this is "normal" because the stupid DPM server stopped working (yellow exclamation) Network interface driver is more than two years old: well, I can do nothing about it (yellow exclamation) Microsoft filter pack not installed: no idea how to do it and no instruction is given! (yellow exclamation) self-signed certificate: I don't think it's a problem some blue exclamations: "exchange resident on global catalog server", "firewall is enabled" and "outlook connection range" but they don't seem to be a problem Anything could explain why mails stuck in outboxes? Backup: No luck. My server is WS 2008 and Exchange is at SP1! According to the notes in that webpage, there's no left to me, is that true? It seems like I have to make that damned DPM work again first...

Yes, Ed is right. Horinius,you can install the Filter Pack on 64bit windows 2008. "The Filter Pack is available for x86 and x64 versions of Windows Vista, Windows Server 2008, Windows XP, and Windows Server 2003."

But performing an offline backup of Exchange involves an interruption of service to clients. Dismount the database, make sure all logs are written to database. Copy the database and logs to another location. Maybe your logs are very large if you rarely make a full backup. Frank Wang

side note (yes a little slow)....I wouldnt be clearing your event logs. They are vital to all sorts of things from troubleshooting to tracking trends (unless you are able to remember every event with the date and time before clearning). increase their sizes (specifically the application logs on an Exchange server) and run a script to save the logs and clear them if you want them gone.

Dismount the database, make sure all logs are written to database. Copy the database and logs to another location. Maybe your logs are very large if you rarely make a full backup. I'm interested in this method. I could plan an interval to stop mail service. Not a big deal. How could I make sure all logs are written to database? What command(s)? When you say "copy the database and logs to another location", I suppose you mean copying their files and folders, right? There are a lot of disk space. That's not really a problem. I'm just thinking what to do if the update to SP3 fails. How could I restore the config and the database...

I did what you thought previously. But it turned out to be impractical. First, it's hard to know when exactly the problem happened, so there're too many events to read through. Even though I had read them through, most of the time I couldn't find out where the problem is => a waste of time. Secondly, if the problem is reproducible, it would reproduce after a event log clear and a reboot. That's how I resolve some other problems. That's why I decide not to keep the logs. They are just useless. Anyway, this is off-topic.

Hi Horinius, First you can use Eseutil /MK filename.chk to see which logs has been written to database. You can do it while database is mounted. This is option. Next, please dismount the database, use Eseutil /MH filename.edb to check the "State" whether is "Clean Shutdown". If yes, you can saft to copy the edb file and logs to another space for offline backup.

I see the same issue: Outlook 2007 - cached mode; Exchange 2007 Version: 08.01.0393.001 (SP1?) and I'm new to this job. so I sent three messages with word attachments: In Outlook I see them in the Sent folder, Outbox is empty. In OWA is see them in the Sent Folder but there are the three messages in the Outbox. and I believe it just started happening with users on the Win 7 PC's and Office 2007. 2003 versions not affected.
