Microsoft Dynamics CRM-“电子邮件”选项卡中附件的注释（注）实体的文件大小属性与设置文件大小限制

Question

I have been recently working on creating Annotations(Notes/Attachments) in Microsoft Dynamics CRM 2016. I have noticed that there are different settings for attachment file size as below.

1. In the Settings Email tab which is ranging from 0 through 131,072 kilobytes

   Microsoft Dynamics CRM -> Settings -> System Settings -> Email -> Set file size limit for attachments -> Maximum file size (in kilobytes)

2. The Organization entity's " MaxUploadFileSize " field setting which is ranging from 0 through 2,147,483,647 Bytes
3. The Annotation(Note) entity's " FileSize " field setting which is ranging from 0 through 1,000,000,000 Bytes . The description says it's " File Size (Bytes) of Note ". Does this mean that it's only applies to attachments uploaded against Notes?

The Annotation Entity Documentation specifies as below:

The maximum size of files that can be uploaded is determined by the Organization.MaxUploadFileSize property. This property is set in the Email tab of the System Settings in the Dynamics 365 application. This setting limits the size of files that can be attached to email messages, notes, and web resources. The default setting is 5 MB.

I suppose " Organization.MaxUploadFileSize " is the global setting and any other specific settings as in Email or Notes take precedence over it for corresponding entities. But this behavior is different from the above documentation.

Could anyone please clarify whether all these settings are interrelated and if so then what's the order of preference among them.

Answer 1

There is only one setting in all this. To clarify:

1. As the MSDN documentation quote says, the Organization.MaxUploadFileSize defines the maximum size of a file that you can attach to an annotation or an email message. That's the one setting you can define or change.

2. The user interface to set Organization.MaxUploadFileSize is located at the bottom of the Email tab under System Settings (where you found it).

3. Valid values for Organization.MaxUploadFileSize are in the range of 0 to 131072 KB.

4. The FileSize field of the Annotation entity is not a setting, it's the actual size (in bytes) of a specific attachment in one specific annotation record. The field is populated once you upload (attach) a file.

   To see an example, create a note somewhere (for example under an account or a contact) and attach a file to it. Now open Advanced Find and search for annotations. If you add the FileSize column to the output you'll see the size of the file you attached.
