Hello Maurice,
There is no such feature in Outlook for Android. From your description, I suggest you try clearing Outlook cache. To do this, since I don’t know the model of your Android device, I will take my Android phone for example. Please open Settings and find App manager > Outlook. Then press Storage > Clear Cache. After completing it, the Outlook cache will be cleared.
If this cannot meet your requirement, we recommend you kindly give your feedback and share your experience via our UserVoice Service. Every customer’s voice is important to us. The related engineers will design or upgrade features referring to customers’ feedback and your ideas will help us to make our product and features better for you.
