Hi Akshay V1
Thank you for posting in the Microsoft Community forum. I hope you're doing well.
I understand that you have question about when will be the offline feature on Microsoft Loop be available. I would be happy to answer your question.
Since Microsoft Loop is still on preview version, there are features that are still being worked on and are coming soon. I highly encourage you to provide feedback directly to our developer team to suggest this feature. During this preview we want to hear from you to help improve your experience. Send us your feedback in the app to help us shape the journey.
To provide feedback, in the bottom right corner on your Microsoft Loop, select Help> Give feedback.
I look forward to your reply.
Sincerely
