Cant delete old e-mails from iphone/Exchange

[LadyAstor]

Does anyone know about iphone exchange accounts and storage?

My phone's memory is currently showing 9.3GB across five accounts. Three are barely used but two ate used heavily- Outlook Exchange & BT.

Ive spent the last few days deleting hundreds of old emails and when i do this, the memory on my phone goes down to 9.0GB but then a few seconds later, its back up to 9.3GB.

Does anyone know whats going on?

I do make sure I delete everything from the deleted items folder/trash can and have even gone into the mail on a desktop and purged it from outlook but my phone memory never changes.

It's bizarre.

Are emails the main user of your iPhone storage?

I'm not sure how much phone storage you have but the operating system can take up quite a proportion?

Have you checked that your overall phone storage General>iPhone Storage and seen what is taking up most of your capacity?

When you delete an email it is held in your trash for 30days, so you wont get the storage back immediately, as per: email
Hope this helps

Thanks everyone.

The majority of my memory is taken up by photos - 71GB of 128. Mail takes up 9.50GB. The rest is things like WhatsApp, Audible, Prime, Netflix etc..

Thanks @widowerbutok i had no idea that mail sat in the bin for 30 days before deletion. I'll see how it is next month.

I spent this evening deleting loads of documents & pictures from iCloud but it dtill shows 4GB as it did before I started.

That's a lot of photos on your iPhone!

Do you need them on your phone or could you just leave them in the iCloud?

I could I suppose but I'm more concerned with the ever expanding and un-deletable e-mails. It's just odd. Ive deleted 5 years worth of Outlook emails in the last 10 days but the size hasnt changed.
