At present, Outlook App cannot open Dynamics 365 for phones with "ms-dynamicsxrm://".
When approving Dynamics 365 (Online) record from Dynamics 365 for phones, the record needs to be opened.
Every time that happens, the customer needs to open Dynamics 365 (Online) and search records.
It takes a lot of time.
It would be much better if record can be directly opened from Outlook App.
It is desirable for the customer to implement this function.
