Log File is Damaged – KB10392001

Leave a comment

KB10392001

Description:  Received an alert that a log file is damaged for exchange

Windows Event Log: Application
Windows Event Source: ESE
Windows Event ID: 440
Windows Event Severity: Error
Windows Event Message: eseutil (10056) JetDBUtilities – 11056: The log file C:Program FilesMicrosoftExchange ServerV14MailboxMailbox Database 1013801047E00.log is damaged, invalid, or inaccessible (error -501) and cannot be used. If this log file is required for recovery, a good copy of the log file will be needed for recovery to complete successfully.

Steps to resolve: There isn’t much to do about this alert. If it’s important and they need it, you will have to restore the file from a good backup copy.

If this happens a lot, use the troubleshooting and diagnostic tools on the exchange database to check the health of it.

Exchange Average Delivery Time – KB10391837

Leave a comment

KB10391837

Description:  Received an alert that the customer’s email is taking a long time to get to them

Common customer description: My mail is taking a long time to send or receive

Probing questions: Is this a common issue?

Is this a recent thing that has been happening?

Is there a lot of people using mail?

Steps to isolate: Send test email to yourself

Check inbound/outbound queues

Steps to resolve:

1. Check the alert, see how long it says the time that it’s taking to deliver

2. Log onto the Customer’s OWA with IE, Chrome, or Firefox on your computer or connect to the server and log onto the OWA from there

3. Send a test email to yourself (your email address)

4. See how long it takes before you receive that email

5. You can also run some diagnostics to see if everything is okay

Additional considerations: This could be an issue with the Exchange database or some setting with Exchange.

Barracuda Appliance Incremental Backups Issue: Circular Logging Enabled – KB10391557

Leave a comment

KB10391557

Description:  Warnings or Failures about Incremental backups being performed for exchange

Common customer description: My backups are failing, can you fix them?

I received an email that my backups have been failing

I got a call that my backups are failing

Probing questions: Was this recent?

How long have you been receiving these emails and/or phone calls?

Steps to isolate: Check the backup report for the errors and/or warnings

Steps to resolve:

1. Log into Barracuda web console

2.  Check the backup report. What is the error or warning that it generates?

Exchange error

3. Barracuda cannot backup the mailbox when circular logging is enabled

  • Why? When circular logging is enabled, transaction log files that have already been committed to the database are overwritten, preventing the accumulation of logs. The log files are overwritten whether or not a full or incremental backup has been run, and a history of previous logs since the last full or incremental backup is not maintained. This is why, when circular logging is enabled, differential and incremental backups of the Exchange databases cannot be performed (since these types of backups rely on complete history of logs). So basically, with circular logging enabled, only information included in the last full backup can be recovered.

4. To work around this, you will have to create a backup job specifically for the exchange server (if the server is a stand-alone server)

To do that go to the Backup Tab, then to Schedules

Schedules

5. On the right hand side, go to Add a Schedule

add

6. Name the backup job (make it obvious – if it’s the exchange call it by the exchange server name)

name

7. Select the server that you want to back up (in this case, it will be mail2)

select server

8. Select the days you want it to back up

days

9. Set the time you want it to back up (Barracuda runs in a 24 hour format – military time)

  • Repeat means if you want the backup to run 2 or more times in one day

Time

10. Choose the backup type – in this case we can’t do the incremental or “smart” backups, we will chose Full instead

Full

11. Double-check the configuration. When you think it’s correct, on the top right, look for a green button called Save

Save

Now you have to watch the backups for a bit, since we changed the backups to Full it might start taking up space. Monitor the job to make sure their disk space doesn’t get full.

Since we made a new backup just for exchange, we have to deselect the exchange server from the previous job(s)

1. Go back to step 5 but instead of adding a schedule, edit the existing schedule.

2. There might be a check box that says “backup all computers and data sources” – uncheck that box and unselect the exchange server. (Don’t forget to say save!)

Additional considerations: If there is only one server being backed up (example: server02 is the PDC, BK, MX, DNS, DHCP), switching the backup to Full might not be an option.

Leave a comment

KB10391343

To use the Exchange Management Console to set the log file location when you create a storage group

 Special notes: You might need to log in as “Administrator” to perform these tasks because they require all of the permissions.
  1. Start the Exchange Management Console on the server on which the storage group is located.
  2. In the console tree, expand Server Configuration, and then click Mailbox.
  3. In the result pane, click the Mailbox server on which you want to create the storage group.
  4. In the action pane, click New Storage Group. The New Storage Group wizard appears.
  5. On the New Storage Group page, the Log files path box displays the default location where your transaction log files will be stored. Click Browse to change the default location.
    noteNote:
    You cannot use the Exchange Management Console to change the log file location for remote Mailbox servers. To create storage groups on other Mailbox servers, use the New-StorageGroup cmdlet in the Exchange Management Shell.
  6. Enter any other information in the remaining boxes as needed, and then click New to create the new storage group. For more information about creating storage groups, see How to Create a New Storage Group.

To use the Exchange Management Console to change log file locations for an existing database

Emails with attachments are delayed – KB10391041

Leave a comment

KB10391041

Description:  Emails are being delayed by hours or even days.

Common customer description: We are receiving emails a lot later than we should.  Sometimes days later.

Probing questions:

When did this start?
Did you recently get a spam filtering service like Securence?
Is everyone affected?
Do the emails that are delayed have attachments?

Steps to isolate: If the client recently signed up and started using a spam filtering solution make sure emails without attachments arrive on time.  If regular emails arrive quickly but emails with attachments are delayed proceed to the next step.

Steps to resolve: Check Exchange and the clients firewall for spam filtering and virus scanning attachments.  Since Securence and other name brand spam filtering solutions scan the emails for infections along with spam, these tasks do not need to be performed in Exchange or on the firewall.

Additional considerations: It has been found that once the spam filter solution is finished scanning the email it opens a socket with the Exchange server.  Exchange is expecting the email to be transmitted within a certain amount of time.  If something like a firewall is also set to scan attachments prior to allowing the transmission Exchange will close the socket due to timeout.  Eventually the email will get sent through if enough attempts move fast enough to beat the timeout.  Better to just leave the filtering to the spam filtering service.
