I now have a second SSD (1TB). Thanks to all who advised at the time.
I would like to move the Outlook pst file to the new drive (as it is much bigger).
There seems to be a lot of confusion with various suggestions ranging from moving the file outside Outlook then allowing Outlook to find it to changing the destination inside Outlook. I tried moving the pst file but Outlook recreated the existing one. I can't see how you could change settings without moving the file. I am concerned about creating duplicates as this could cause havoc.
Could any one point me in the right direction? Thanks
