Hi Rodney,
Good day and thank you for taking the time to share your feedback. This does not seem easy to deal with, and your message comes through clearly.
I understand your concern regarding the retirement of the Send Availability feature in Outlook for iOS and Android, and I agree that it was a very convenient capability.
However, please note that this forum is primarily intended for community discussion and peer-to-peer assistance. Moderators here, including myself, are regular users as well and do not have the ability to change product features or influence Microsoft's design decisions directly.
With that in mind, your feedback is valuable, and it is a situation that many other users may feel similarly about. To help ensure your comments reach the appropriate product team for consideration in future improvements, I would strongly encourage you to submit your feedback through the Outlook Feedback Portal. Customer feedback plays an important role in helping Microsoft understand how features are used in real-world scenarios, and your voice could help bring greater visibility to requests for the return of functionality that many users found beneficial.
Once you've submitted your feedback, feel free to share the link here in the comments. I’ll be happy to upvote it to help bring more visibility.

I hope the information helps guide you to the next steps. Please feel free to reach out if you need further assistance.
Thank you again for your time and for raising this important usability concern.
