how do I mark all as read?
Thank you for using Outlook Mobile and sharing your ideas with us. We really appreciate your support.
It is currently already possible to select all emails in a folder at once. To do so, long press on an email until a checkmark appears at the left of it. A “Select All” option will then appear in the top right corner. This will let you perform actions on all emails in any folder at once, like deleting or moving to another folder.
Having trouble finding the feature? Let us know through the Help section of the app. You may reach them by going to the app’s Setting > Help and Feedback > Contact Support
Thank you again for your support, we look forward to hearing more of your ideas very soon.
All the best
The Outlook Mobile Team
