I am using a Lumia 730 Windows Phone which I recently updated to Windows 10. The update is installed and the very next day it gives a message for more updates. When I try to install, my phone is out of phone storage. Now in order to free up some space I deleted my email accounts (all other than Microsoft). But I still can't see the space available and under Storage Mail & Messaging is still showing 800 MB. Any ideas how can I free up some more space from there?
I recommend some steps to reduce your storage consumed by Mail & Messaging app.
- Backup your SMS & MMS into SD card by using Transfer My Data app by Microsoft. Delete the SMS and MMS on your phone. You can restore it using the same Transfer My Data app after update.
- Unlink Skype from Messaging app. Use Skype app instead. It can be moved to SD card if needed.
- Change your mail settings so that the Mail app will download only the email from last 3 days.
- Restart your phone.
I also have Lumia 730. You probably upgraded your phone from Windows 8.1. Go to storage app & see what is consuming more storage. Delete or uninstall some unwanted apps. Try moving some low duty apps (which you do not use every time or simply like a dictionary app) to SD card. Try moving songs, videos and photos to SD card. If you have upgraded to Windows 10 using Windows Insider production ring method. Try resetting your phone or wait for Redstone 1 update. It will probably have solution for this.
