Trash icon in my Inbox

To do Mass Delete you need to do the following:

• Go into Settings / Passwords & Accounts / Gmail account
• Tap on the account (e.g. myname@gmail.com)
• Tap on Advanced
• Under Move Discarded Messages Into, tap on Deleted Mailbox
• Tap on Account at the top left of screen
• Tap on Done
• Tap on Accounts
• Close Settings
• Close the Mail app if it was open
• Reopen the Mail app and go to any of your Mailboxes, click Edit and then Select All and you should see at the bottom - Mark, Move, Trash (or Delete)

It's important to close out of Settings and the Mail app for the changes to take affect.

Not sure I understand.

Are you saying when you open an email and want to delete it, the Trash icon in the bottom right corner is not there and only the Reply icon is there?

Is your email account Gmail?

For Gmail accounts the Trash icon is not a trash bin but a different looking icon left of the reply arrow. At least that's what I show for my Gmail account. Maybe you have to setup mass delete in my other post before you see the delete icon.

Sorry, the post with the screenshot is incorrect. That icon I show in the screenshot is for archiving and in Gmail mail goes to the All Mail folder.

Once you do the steps in my post above, that icon will change to a Trash can.

If you have Google mail set to archive the trash can will not appear. It does show on my iCloud account.
