The attempted operation failed. An Object could not be found Outlook

When selecting Rules and Alerts from the home page of Outlook, you will receive this error.

This can actually be caused by a number of issues, such as:

  • Corrupt rules
  • Broken search folders
  • Corrupt Outlook profile

To fix this issue, try the following (in order of less destructive)

  1. Run Outlook.exe /cleanrules from the command line. This will remove all rules from Outlook and Exchange.
  2. Delete all search folders and create a default search folder with Unread mail as the default
  3. Re-create the Outlook profile. This is a last resort, but in most cases will work. This indicates something wrong with the local configuration of the Outlook profile

 

Performance Tuning Forefront TMG 2010

Microsoft Forefront TMG 2010 has been a solid product. It has not had an update in some time, and that’s a shame.

I was reviewing my TMG server a few weeks ago in order get a bit more performance from it. The server is virtualized, and currently only gives me around 50-60mb/s throughput with all its rules. I wanted to increase this and make it more responsive in the process.

So let us proceed:

#1 Sort Rule Priority

Like most other firewalls, TMG processes rules from top to bottom. If you have a frequently accessed rule, like web browsing, for example, put this at the top. For me, this was a spam filter listening rule. TMG had connections coming in for the spam filter at the rate of 5-10 per second. I moved these to the top

tmg1

 

The next rule you want to sort out is traffic from TMG server. I would generally add this as my second/third rule.

tmg1.1

After this came my office outbound rulestmg2

 

After this came the rest of my rules which consisted of various servers/voip etc.

#2 Disabled Legacy Services

Since TMG is now discontinued, many of the services in TMG are no longer updated. It’s up to you, but you might as well disable them to recover some performance. These services are:

  • IPS
  • Spam Filtering
  • Virus and Content Filtering

Ensure each one is disabled. You might be a bit hesitant to disable these. If you check your definitions, you will find they have not been updated in some time.

#3 Remove Old Rules

Lastly, remove any old rules. We don’t tend to look at firewalls often. So this simple task often gets overlooked.

As well as removing the old rules, ensure that you make your listener rules only listen to what’s needed. This will cut down on processing time.

Conclusion

TMG is a great product, but now beyond its used by date. TMG will always hold a special place in my software archive as a product that could have become a great firewall appliance <3

I hope this helps.

Storage Spaces White Paper – Fujitsu

I’ve recently come across this great PDF from Fujitsu on Storage Spaces. I highly recommend all those who are trying achive maximum performance from their storage spaces take a look.

The white paper goes over each storage space type, different cache settings and drive layouts. All of this is graphed.

WinSXS/Installer Cleanup Windows 7,8 & Server 2012 with Patch Cleaner

I originally had a post on how to clean up WinSXS from 2014. However, I have come across a program that I have tested, and works very well.

The program is Patch Cleaner. This program scans your Installer folder to check if there are orphan files relating to programs or patches you may have removed from your computer. Any orphan files Patch Cleaner locates can be removed.

I have tested Patch Cleaner on Server 2012 and 2012 R2, including production terminal servers with 100 users. I have no had any issues thus far.

With Server 2012, running Patch Cleaner was removing on average 20GB+ on each server.

I would recommend checking this out if you are still stuck for space.

Disable Windows Update Services (WSUS) – Small Business Server and Doman Controllers

Windows Update Services, or WSUS can be a real pain at the best of times. On Small Business Servers, which are often neglected, some strange issues can arise.

The most common issue is that WSUS goes crazy and downloads everything. Yes, this does happen.

You may not know, but you shouldn’t uninstall WSUS on a domain controller, IE Small Business Server.

Here is how you can disable it and clean up the mess.

  1. Under Options, select Products and Classifications 
  2. Unselect everything, and then select Bing Bar. You need something selected.

  3. Under Classifications, select Critical Updates
    2015-11-13_12-21-47
  4. Remove Automatic Approvals
    2015-11-13_12-23-29
  5. Run the Server Cleanup Wizard with everything selected
  6. Once this is done, you can leave WSUS as is, or you can disable the service
    2015-11-13_12-25-46
  7. With the service stopped and disabled, you can also delete the content database. Only do this if you are never going to use WSUS again.

Hopefully this has helped someone.

Windows 10 “Out of Memory” when left idle

You may have come across this issue when you’ve upgraded your computer to Windows 10. Upon returning to your computer, the screen refreshes slowly and applications appear to have crashed due to memory issue.

There have been many suggest ways to fix this, but the simplest way is to do the following:

  1. Open Regedit by pressing Windows Key + R and typing regedit
  2. Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management
  3. Change the value of  ClearPageFileAtShutDown to 1
  4. Reboot your computer

This will wipe the page file on reboot.

This may increase the shutdown time of your computer, but it will fix this error. The root cause of this error is an incompatible driver on your system. I will follow up with an article on this process.

Installing Disk Cleanup (cleanmgr.exe) Server 2008 and Server 2012

It’s annoying that Disk Cleanup (Cleanmgr.exe) is no longer installed by default. You can install Disk Cleanup by installing the Windows Desktop Experience – but, there is another, less annoying way…

Now go to Run and type cleanmgr.exe

cleanmgr.exe

You will now see Disk Cleanup run.

Unfortunately on Windows 2012 R2 you must install the Windows Desktop Experience.

Error while preparing to send sharing message (Outlook 2007/2010/2013/2016)

I got the following error when I had migrated a customer from a Small Business Server to our local Hosted Exchange.

Outlook on a domain looks to Active Directory to get the auto discover information. If you run the Outlook connectivity tester on the affected computer, you will see that it returns the local SBS server autodiscover settings, even if you have configured Outlook to use an external provider.

The simplest way to fix this if the SBS server is still in used and Exchange is still installed, is to run the following commands:

Get-ClientAccessServer | Set-ClientAccessServer -AutoDiscoverServiceInternalUri https://mail.externaldomain.com/Autodiscover/Autodiscover.xml

And

get-autodiscovervirtualdirectory | Set-AutodiscoverVirtualDirectory -ExternalUrl https://mail.externaldomain.com/Autodiscover/Autodiscover.xml -InternalUrl https://mail.externaldomain.com/Autodiscover/Autodiscover.xml

This then points the Outlook client to the correct external Autodiscover service.

If you have any questions, please let me know.
