Sending, receiving, and organizing email in Outlook on the web for business
Hi jtfox1976,
Greetings
Thank you for posting in Microsoft 365 Community forum.
I understand you want to send your availability in Outlook on the Web as you can send in Outlook mobile as shown in this article Send meeting availability in Outlook mobile (microsoft.com), please correct me if I am wrong.
I checked from side, and I could not do the same in Outlook on the Web or find any documentation on it. As a workaround if a user has permission they reschedule from their end.
Given the situation I would advise you submit your feedback and recommendations via the following portal Outlook · Community (microsoft.com) to let the related programming team know. And they should be the quickest route to get your comments to the related programming developers 'ears.
Microsoft will always focus on customers experience and they would add some good features to our products in future according to the number of votes your suggestion gets.
Your kind understanding is highly appreciated.
Kind regards,
Simbarashe
