I need an Outlook expert to assist in combining numerous .PST files.

Job ID: 35385566

Budget: $30 – $250 USD

Good afternoon.
I have Microsoft 365 on my laptop.
I need an Outlook expert to assist in combining numerous .PST files (about 6) that I have 'accumulated' over some time.
I also need to ensure that when combined that all the duplicates are removed.
These are also duplicated in my OneDrive.
I have tried to do this myself, however I seem to just make the situation worse and end up with numerous duplicates.
The ideal would be to end up with 1 Outlook Account file in my name, 1 Outlook Archive file and 1 Gmail file linked to my Outlook Account.
Obviously an Outlook backup will be required to ensure no details/information is lost.
How would this project be executed.
I look forward to hearing if you can assist me with this Project.
Kind regards - Alex
