Hi,

I am leaving for jobs from my university and have a lot of .ost file around 47.8 GB and want to open it into my Outlook 2019 on my laptop and Outlook 2016 at my desktop.

Is there any solution for open my ost file in Outlook??

So, please reply me soon for best solution before I will be joining another office.

Do you still have the account that created it? If so, the easiest way is to export it to a pst. First double check and make sure you are syncing everything in File, Account Settings - open account settings and double click on the account to check the sync slider. Then Export.

If you have the ost and recently deleted the account, you may be able to use system restore to go back before it was deleted, then export the ost.

If you only have the ost, you need a 3rd party application. See Convert an Exchange or IMAP .OST to a .PST for the different ways to convert and ost to pst and for 3rd party recommendations.
