Emails not syncing across Mac, iphone, ipad

[#1]

I have set up an imap account and I'm having an issue trying to get the email threads to appear across all.
If I reply to an email from my iphone, it doesn't appear on my Mac etc. etc.
I want the threads to an email to appear on all.
I'm using Outlook on the Mac.
Any suggestions?

Try looking at your folder list - Have you got more than on Sent folder (Possibly Sent, Sent Mail, Sent Items or Sent Messages)?

[#3]

On each device have you "mapped" the client's SENT, TRASH and DRAFT folders to those on the IMAP server?
If you have not. anything SENT, DELETED or Drafted will remain solely on that device.

I do just have the one Sent folder thanks.
I think it might be an Outlook on Mac issue.

First for email items sent from your phone to be visible elsewhere, then your phone must place its sent items in the IMAP server's Sent Items folder, not the phone's local sent folder.
Likewise Outlook on the Mac needs to be configured as IMAP and have its sent items also configured to be on the IMAP server.  Configured like this, emails sent from any device are available on all devices.
