Storage used up even after deleting apple mail app

I’ve sorted mine.

My mail app was showing 13Gb. Tried all the suggested but in the end I downloaded all the stand alone apps for the third party email accounts. Gmail, OutLook ect. I did keep gmail signed in but for contacts and calendar only and now Mail is only using 1Gb!

The other apps have much better data usage settings to help minimise storage usage.

hope this helps 👍🏼

I posted this as I couldn’t find the original post

”This is not a question, but a reply. I had this problem, like a lot of other people, and deleting all messages had no effect.

Yesterday, I had to do a Reset All Settings because of a keyboard problem and found that this reduced Mail Documents and Data from 3.5 Gb to 17 Mb!”

Also works for other programs taking up lots of space, such as Firefox.

I had 7.5gb data after deleting all accounts & MailApp. Looked around & found no working solution in forums. So, decided to do following… go to iPhone Storage->reinstall Mail App->delete App. And repeat the same several times within the Storage Screen. With every deletion the App starts losing significant data. In about 10 cycles the Mail App was completely deleted. All the best!!!

I was having the same issue and was only able to resolve it by doing a backup, erasing all content and settings, then restoring from the backup I made. I have a 64gb iphone 12 and I was constantly running out of space regardless of what I was deleting. After I did this my space used dropped to around 40gb, so it freed up almost 24 gb of nonsense.

iOS 16 instructions

BACKUP FIRST

Settings > click your name at the top > iCloud > iCloud Backup > Backup Now

RESET

Settings > General > Transfer or Reset Phone > Erase All Content and Settings > Continue

RESTORE

Follow the instruction from the blank screen to sign into a wifi and your apple account first, then restore it from the backup you just made. It will take some time to download a lot of the apps again so plug it in and let it do its thing for a while. You'll have to set up FaceID and sign into a lot of apps again, but the space that was created from the process seems worth it to me.

Hope that helps!

Thank you ! This is worked !

1) Delete the mail accounts

2) Delete the mail app from the main screen

3) go to settings > general > iphone storage > mail > reinstall app

repeat steps 2 & 3 until you have cleared all the mail storage that was being used.

each cycle you see it decreasing

I did what you said and reinstalled the app and deleted it again. Took me three times however I now have my 9 GB back that mail was taking up. Thank you. I have deleted all mail accounts on my phone except for other apps that hold my mail. I am not longer using the apple app for mail.

I fixed it on my phone and iPad. Tried all the stuff mentioned here but with some additions.

first off I did this all my with iPhone and iPad plugged into the wall.

reinstalled Mail and went into settings and deleted the accounts. Then deleted the mail app. At this point it is still showing up in my storage. I then restarted and then I closed all my apps and started opening some random ones including my gmail app. After this I checked my storage and mail was gone. Then I resinstalled mail and it was a small file (all data gone) and I set my email back up in the app.

hope it works for you too.

Commenting to alert Apple. I have *50GB* of "documents and data" being used on my "Apple Mail" app.

Why and how is this happening?

Please reply with a solution.

Did anyone ever get an easy way to fix this issue? Mine is using up 25gb, apple are a joke

I also have the same problem. I was hoping it would be fixed with iOS 15.5, but sadly it isn't.

Same problem! Did anyone solve it??
