I upgraded to the MS Outlook 2016 client on my PC. I use it with a gmail account.
When I added the account, it creates a new .ost file, and it imported all of my emails since 2006. This grew the .ost file to over 1gb.
Since I already have those old emails in a previous .pst file, I just deleted them all from the .ost. Once everything is deleted, and trash emptied, etc. I compacted the .ost file from within the Outlook file management area, however, it didn't really clear out much space at all.
What am I missing?
I don't want to delete and re-create the .ost file as many suggest on various support forums, etc... because I think it would cause outlook to re-import all of those emails again.
How can I re-claim this space?
