CRM Registry Settings


Today we have a relatively serious topic: Registry Settings. Unfortunately this can be an extremely boring topic – so I have opted for a more casual and sarcastic style.


Microsoft Dynamics CRM 3.0 has a boatload of additional settings which many of you might be unaware of. These additional settings are stored in the registry of web server machines. If you don’t know how to edit the registry – then you probably shouldn’t be (as patrician as that sounds – trust me – it’s for your own good). Wikipedia has a nice overview of the Windows Registry or there is the rather dry MSDN version.


Let’s start with supported vs unsupported. If you modify a registry setting which is not documented in our SDK (the downloadable one or the one on MSDN) then it is an unsupported modification. The undocumented ones are used for the internal operation of the system: changing them only makes you look smart – it doesn’t actually make you smart. Those technical readers out there will be aware of the type of person I’m referring to: the one who unnecessarily modifies their registry to impress others (a kind of Fast and Furious of the computer configuration world).


Here is the list of items from the SDK which you can modify:

One of the most common settings to be modified is the maxfileuploadsize setting. It’s been blogged a couple times by some others (Menno and Anne) but recently I’ve been getting a few questions about this. CRM restricts the size of files for import (for email attachments, regular attachments, sales literature documents and customization import files) via this registry key. The CRM client also has the same setting which it uses for uploading files. You can find the client key here: HKEY_CURRENT_USER\Software\Microsoft\MSCRMClient.


Another favorite is the MaxRowsPerPage. This is typically used when you have integration code requesting large sets of data using the FetchXML query language inside our web services API. Note that the max value is still 5000 records.


If you are using the CRM integration products you can also adjust the database which the product uses. See this post from by our Connectors Team.


Those seeking to tweak the performance of their Terminal Service or Citrix implementations should also check out this blog post by John Song.


Remember that any time you modify the registry of your CRM implementation you will need to make these changes on all the web services in the load balanced cluster.

    Hello,

    Does anyone knows whether these settings are still present in CRM 4? Were they perhaps expanded?

    Thanks!

  3. Is there a registry key which would automatically set the checkbox for including the Local Data Group in the 15 min sync cycle?  This is found in the Set Personal Options | Local Data tab.  I’d like to avoid users having to navigate to this option and would rather push a reg key to them.

    We are running 4.0 with RU6 on Outlook 2003.

    Thank you!
