Moved from hosted exchange to O365, now getting a Trojan blocked notification every 10 minutes for Outlook

Hi

I just moved from hosted exchange to O365 for my email. I have set up a new account in outlook and imported my old .pst file and all my emails / contacts etc are now in one place which is great.  Office online and the iPad mail has no problems with my email however the local Outlook 2021 application has been getting the same notification from KTS web anti-virus since this move, here is an example: (I've removed the specific MailboxId details, MD5 hash and computer username and replaced with "***")

I've also noticed that Outlook is now not connected to the exchange server. I have updated my computer and office and rebooted and still the same issue occurs.

Can anyone advise what this is and what to do with it please?

Thanks very much
