What’s happening?
Customers are facing limitations regarding file size for attachments in Dataverse, specifically the inability to upload files larger than 128 MB.
Reason:
By design.
Resolution:
The Organization.MaxUploadFileSize column specifies the maximum allowed size of a file in bytes for an attachment and note, and other kinds of data, such as web resource files used for model-driven apps. The maximum upload file size limit applies to the size of the file in Base64 encoding. A Base64 encoding produces a string that is larger than the original byte[] file data.
The default size is 5 MB (5,242,880 bytes) and the maximum value is 128 MB (131072000 bytes) and can be set in the email settings for the environment. More information: Manage email settings
