After decades of using Outlook only with a local PST file, I see the need use Outlook online. I need my different devices to be able to access old emails and for access to sync and be consistent across my PC, my tablet, laptop, etc. I have the proper license, but have no idea how to clean up my local PST, upload eveything to the cloud and then get it to work seamlessly between devices. Has anyone found a good resource I can use? I don't even mind spending a few dollars if it works. Thanks.
