Move email/calendar from Outlook 2010 to Microsoft 365
I am preparing (not without trepidation) to move a home email account in Outlook 2010 (Windows 7) onto a new laptop with Microsoft 365 (Windows 10). The old setup has a lot of folders and I need to move folders, inbox, sent items, contacts, and calendar. I would appreciate any recommended articles/links or advice. The one that has been helpful so far is: https://www.slipstick.com/outlook/config/move-outlook-to-a-new-windows-computer/ by Diane Poremsky. I am semi-comfortable dealing with PST files which appears to be the route to go. My areas of concern/weakness in a nutshell are:
1. I want all the older folders and emails to live on the laptop, not in the cloud–they are largely just for reference. Do I need to do anything specific to achieve this?
2. I want to continue to access this email account from my phone (Android), from a Gmail web page, and from Outlook on the new laptop. Do I need to do anything specific to achieve this?
3. I want to set up my calendar so I can access it from my phone as well as the new laptop and share it with other family members. This may be a separate topic but any pointers here would be great.
Thanks very much!
