Hello and Welcome. My name is Michael.
To retrieve deleted emails you have a few options.
- Depending on which device you deleted them from it could give you different alternatives of retrieval. For example if you deleted them from your phone, your phone Mail App might have different policy of mail elimination than if you deleted them from your computer's mail based browser.
Is very important to check the Trash Bin FROM THE ORIGINAL DEVICE YOU DELETED FROM.....they might still be there.
Please let me know if you require additional help on this matter.
