In Outlook, this is found under the File tab. Click Options, then Mail, and scroll down to the Send messages section. Uncheck the box next to Delete meeting requests and notifications from Inbox after responding

Ah, excellent. Does that option synchronise across the app and OWA version as well? thanks

dear agwalsh,

What version of the app and what version of Exchange for the OWA question?

I believe these options should be available in the app and on OWA,  but I rekon it doesn't synchronise but cannot be sure.  

Give me the required information and I will do my best to answer your question.

Kind Regards
