Description:

From time to time outlook client throws an exception while tracking email with attachments that attachment is too large. This is strange error due to fact that eg. email has two attachments (10Mb each) and CRM setting section is set to 32768 or 30720 (this two different values is another error).

Below I describe steps which provides overwriting build-in limitations – my goal is to set 64MB

Solution:

First of all – this is unsupported method, any changes can be overwritten during RollupUpdate instalation.

1. IIS setting modifications
   Open ISS manager -> Select CRM site -> open Request Filtering settings -> edit Feature Settings -> set Maximum allowed content length to 67108864

   
   

2. web.config modifications
   Edit configuration file from location C:\Program Files\Microsoft Dynamics CRM\CRMWeb -> search for first occurence maxRequestLength and set it’s value to 65536

3. SQL modifications
   

   UPDATE Organization
   SET MaxUploadFileSize = 67108864
   
   SELECT MaxUploadFileSize FROM Organization
