Microsoft Office 2011 Mac 64 bit upgrade

I have followed this tread but am still unsure how/if the emails in Outlook 2011 for Mac will transfer automatically when I install Office  2019 ?

I purchased Microsoft Office 2011 along with the purchase of my MacBook.  I did an upgrade yesterday only to find that Office 2011 will only run on 32 bit.  The upgrade now requires Microsoft Office to run on 64bit.  I read in many places that Microsoft has no intentions of supporting this upgrade so therefore, I can no longer safely use this software, that I purchased, on my mac.  Microsoft is forcing me to purchase something I have already purchased earlier.  I do not care if there are newer versions of Microsoft Office.  I purchased Office 2011 and Microsoft should still honor that purchase by providing the 64bit upgrade.  I contacted support thru their chat box and was only directed to this site where I can look up or post my own questions.  Really great customer support Microsoft! Thank-you! NOT.  I wish to have a refund or a product key to another Microsoft Office that will run on Mac at 64bit. I'll be holding my breath awaiting even more outstanding customer service.

The open source alternative is OpenOffice with its more robust fork called LibreOffice. There's also a Mac-only fork called NeoOffice. If your needs are not very demanding feature-wise, these can do the job for you. These programs share most of the same industry standard file types used by Microsoft Office. At the very least you get good file compatibility and can still share with Microsoft Office users who will see these files open in "compatibility mode" to protect them from using unsupported features.

I don't think it's reasonalbe to ask Mac users not to update their OS. Taking that route means you'll end up with no support from either Apple or MS. I will be contacting MS (if such contact is even possible these days) to express my disappointement but I guarantee that they will not care. I'll be looking at open-source alternatives.
