and work with your Email server and stores your messages directly to your device.
If you have a larger number of accounts synced with the app, and/or your sync settings are set to a very large time frame (such as "All"),
then you may use up a large amount of storage space on your device.
To fix this, please remove any unnecessary accounts from the app and change your sync settings to a shorter time frame.
Additionally, you can go to your device's settings-> storage and in the MailWise application, clear the data/cache.
