Users claim unlimited GPT-5.5 access through Microsoft 365 Copilot
A Reddit thread in r/microsoft_365_copilot reports that some company accounts show no usage caps when accessing GPT-5.5 and Think Deeper mode. The claims remain unconfirmed by Microsoft. No official documentation lists model names or rate limits for the service. The discussion centres on whether this access explains the per-user licence cost.
Before this thread, most users treated Copilot rate limits as an implicit control that kept sensitive work out of the tool. The reports remove that brake. Now the constraint shifts from technical limits to human judgement. Teams without clear data rules will see more unchecked prompts and higher downstream review work.
Analysis
Treat the rumoured unlimited access as a governance exposure, not a productivity windfall. Require every team to publish a one-page data-classification rule that states which document types stay out of Copilot before the next licence conversation.
