I have 2 Gmail accounts that I am receiving in Outlook 2016 (Office365) as IMAP.
they are huge accounts that have over 35.000 Emails.
I am about to change my Laptop and would like to transfer those accounts to the other laptop without having to re download them again ( it would take weeks to get it done! )
my problem is that IMAP are creates as .ost and I have looked around and it seems there is no way to do so.
Did I look deep enough ? Is there out there a solution to my issue ?
