How long does it take for email messages to be permanently deleted from a web based email provider such as Outlook or Yahoo?
When you delete an e-mail there is a period of time that the e-mail will still remain accessible from the trash or deleted folder. That period varies provider to provider and client to client, so how do you know how long you have to recover a message?
The best way to find out is to refer to the e-mail provider’s website. Below is a list of links to various e-mail providers’ retention information on deleted/trash e-mails. Some providers list a specific day count, while others just advise how to un-delete messages and do not list a specific time they’ll guarantee that option is still possible.
- Yahoo E-Mail Policy 
- Gmail E-Mail Policy 
- Outlook.com E-Mail Policy 
- iCloud E-mail Policy 
- Outlook Deleted E-mail Settings
