Hi,

Can someone tell me if there is way to increase size of individual attachment uploaded via portal to Azure Blob? Currently individual attachment bigger then 125MB keep crashing and timing out the application.

Thank you in advance!

Hi @hugobernier ,

Thank you for your prompt response, however, the answered post does not help in my case as I'm looking for a way to increase individual attachments size in my portal to couple of GB. Is that possible at this time? For a user to upload couple of GB file to the portal?

I have implemented Azure Blob, but as mentioned the limit with it is set at 125MB, so I'm looking to see if there is a way to change that limit to a couple of GB? Thanks!

The DataVerse setting is the maximum you can upload. To work around it you would need to write your own code to do it e.g. upload via an API call (where you created the API in Azure etc) - if you attempt to store, or process such a large file via DataVerse or a .Net plugin it will timeout.

I haven't done it myself, was just suggesting a way that you could achieve it. For the Portal 'talking' to the Web Service you would probably make use of the Implicit Grant Flow https://docs.microsoft.com/en-us/power-apps/maker/portals/oauth-implicit-grant-flow (there is some sample code linked to in s Section at the bottom of that page).
