Yes, please consider PST for local copy while cache mode for mobility

    I have a very similar need to this thread but cannot figure out how to make it work. 

    I used to primarily use Outlook for Mac 2018. I have a very large outlook file, of over 100GB, stored on the local machine. I have just upgraded to Office365 and I would like to be able to export the Outlook data file up to the 'Microsoft Cloud' where it would be stored permanently. The main reason for wanting to do this, besides saving space on the machine, is that I want to view, use and edit all past emails etc on any machine. I want to be able to write an email on the Mac and then log on on a phone/iPad or PC and see that email in the sent folder. Moreover though I want to export the huge file archive from Outlook so that I can access this from different machines, and everything is always kept up to date across the machines. 

    I have exported the file archive before upgrading to 365, but I can't figure out how to 'upload it' and have this saved in the cloud so that it is the 'master copy' and always accessible across different devices. 

    I would appreciate some help, 

    Thanks,

      I don't know if this helps you in any way... as this is what I did with Outlook 365 on Windows 10 and not on the MAC as I don't have any experience with MAC yet.

       

      I realized that having such a large Outlook pst file could severely impact the performance, so I created 2 pst files.

       

      The first PST file has all emails (Inbox, Sent, Deleted and over 200 other folders) from the previous 18 months.

       

      And a second archive pst file, that contains all older emails.

       

      The first PST file is the one that is synch'ed to the Cloud... and can be seen on my Windows desktop, Windows laptop and iPhone.  It is also stored locally on my machines... as an .OST file.

       

      The 2nd Archive PST file is just a local file.  I have a copy of this on my desktop and laptop.  And can choose to search this archive pst file when needed.

       

      But I understand that the real question is whether Outlook for MAC can provide local copies of PST files (or OST files) that can be accessed when not connected to the internet.

       

      Hopefully, someone with more in-depth experience of Outlook on MAC might be able to provide a solution for this.
