Updating maximum file size does not have any effect RRS feed

    Hi all,

    I need to update the maximum file size that a Note's attachment can be. I have done the usual step of going into Settings -> Administration -> System Settings -> Email tab and changing the value in the Maximum File Size box. This did not let me attach a file larger than 5MB.

    When uploading a larger file, I just get a "An error has occurred" message without any further information (the "Download log" button is greyed out). I've been onto the database server and checked the Organization.MaxUploadFileSize but this value concurs with the System Settings value.

    Does anyone know if there's a value anywhere else that I need to update?

    look in the registry.  I think it's HKLM\Software\Microsoft\MSCRM for maxuploadfilesize.  update that.  Also, check IIS and see if there are any timeout settings or file settings in your IIS configs.  CRM can't override IIS settings for stuff like that.

    Hi Wayne,

    Thanks for your reply. I tried all of these settings and they all seemed to work up to a point but then the specific error about file sizes just changes to "An error has occurred" - this would suggest that there's something on the server that's blocking these files and IIS would be the main suspect for this.

    Do you have a plugin on the create event of the Note entity (or a plugin that runs on the create event of every entity like an autonumber solution)?

    No, there's no plug in on the Notes entity. There's an autonumber solution on Cases and Opportunities that I've added and my customer would've tried adding the Note from within one of these records but I've tried adding a Note independently of these areas and still get the same error.

    probably the autonumber solution is registered on the create step of any entity, for a test try to disable the autonumber plugin and add a big attachment, check the result

    I've done that but the error message does not change.

    I had the similar issue (fail to attach files bigger than 5mb) with a CRM online instance before, the error trigger was when a plugin was attached to the create step.

    for your case try to contact Microsoft support.
