Copilot Prompt Limit Difference Between Licenses

[jacksproul_tds]

Hello,

Based on a user's M365/O365 license, are prompt character limits changed for Copilot for M365 prompts? For example, a user assigned a Business Basic license has a 2,000-character limit for prompts, and a user assigned an Office 365 E3 license has a 4,000 character-limit for prompts. Why is this the case? Does licensing change anything with prompt limits?

Thank you

Can you share a screenshot of the character limit, because at our end the prompt limit is 2,000 characters for all licenses type such O365 E3, M365 E3, O365 E5 or M365 E5?

Im already concerned about this same question, because using my Microsoft 365 student account i have a 8k character limit but i have restrictions to other things like sending images to Copilot.
