1MB attachment limit for Microsoft 365 Copilot

Good morning, Copilot community!

 

Referencing the Microsoft Answers post https://answers.microsoft.com/en-us/msoffice/forum/all/why-is-copilot-pro-not-allowing-files-larger-than/7ac70c22-d54f-4c21-a9e8-ce5261897b97, is there an update about if or when the 1MB file attachment limitation will be lifted for organizational Microsoft365 licensed users of Copilot? 

Thank you

    Yesterday, in a webinar about Copilot Chat held by Microsoft representatives they mentioned that this limit of 1 MB will be removed for everyone by the end of Q1/2025 :-) Without the license you have now the same file size limit which is 512 MB. This is all according to the comments in the webinar by Microsoft representatives, in the web I have not found confirmation. People in our company tested it and it worked.
