User Code Host Service keeps stopping

I recently came across a this error a few times on different SharePoint 2010 environments. Initially, I came across the error “User Code Host Service is too busy…” , then I stopped and started the User Code Host service from Central Administration. This then caused the error message telling me that the there was “No available Sandbox code execution server  could be found”.

I then looked into the error logs and found some errors about the User Code Host service and Performance logging. I opened the SharePoint log file, and scrolled down to the bottom of the file. Then I did a CTRL+F for “Perf”. I then found the error relating to starting the code host service and how the service has stopped.





I came across these this fix that resolved the issue of the User Code Host Service keeps stopping:

Operation is not valid due to the current state of the object.

I came across this error today while attempting to update my WSP via Sharepoint Powershell console.

I have been working on creating calculated fields in xml and the requirement was to include the <= (less than or equal to) symbol in the schema. Because this didn’t work, I changed this symbol to &leq. When I atttempted to update the solution, this is the error I got in the powershell window

Operation is not valid due to the current state of the object.

I removed &leq; from the fields xml and list xml schemas and this fix the problem, but not the requirement.


But if you are ever working with fields, content types, or lists schemas and you come across this problem, the likely issue would be invalid symbols or syntax in the xml.

Outlook 2007: cannot open your default e-mail folders. The information store could not be opened

I came across this error in my development environment when I need to do some work with Outlook 2007. After installing it, I started up Outlook and ran through the configuration wizard. Because there was no exchange server in the development environment, I just put in dummy data into the values.

Here is were I went wrong. Outlook stored the dummy data I put into the  configuration wizard and every time I try to open up outlook, I would get a error message telling me that the Exchange server I provided does not exist or is not online.

I tried uninstalling and re-installing Office 2007 but still no-go.

Then I found out the Outlook settings had been saved to my machine!

The solution: Deleting  the Outlook profile stored on the machine brings back the initial Outlook configuration wizard the next time you open Outlook!

1. Go to Control Panel -> Mail (Do a search for mail in the top right search box)

 2. Select Profiles

3.  Select the Outlook profile that was created by the configuration wizard for you

4. Hit Remove!

5. Start Outlook from the Start menu
