Remove duplicate emails in Outlook for Mac

[mikeroberts]

I'm running Outlook for Mac (v 16.16.14) on a Macbook Pro with OSX 10.13.6.
Because of reasons related to lost emails, I have had to combine multiple Outlook identities into one. As a result, I have duplicated many of the emails and would like to remove them.
This version of MS Outlook doesn't have a clean-up tool. There are some third party apps available, but I can't find any reviews or objective assessments. Can anyone recommend a method to remove duplicates?

Hello and welcome.

Unfortunately, I am not very familiar with the Outlook app on the Mac, nor any duplicate finding software for Outlook emails. So, I cannot recommend any solutions. I would be happy to look at what you find, if you want a second-opinion.

Sorry,
