Need To Backup Office 365 Personal Or Outlook 2016
I'm using Acronis TI 2018. I recently successfully cloned my laptop's 500GB primary drive to a new, empty and unformatted 1TB drive. The new 1TB drive is now installed and working just fine. I now want to do a reset of the Windows 10 Pro x64 OS that I cloned. I don't mind reinstalling most applications but I do not want to reinstall my Office 365 Personal as the included Outlook 2016 contains 27 email accounts, 25 of them being Microsoft email accounts and the other two being sbcglobal.net POP3 accounts. It's a real pain to configure 27 email accounts and Microsoft limits the number of Exhange email accounts per user to 10 unless I make a registry change that will allow me to put all 25 of the Microsoft email accounts on their Exchange servers. That's the only reason I'm able to have all the email accounts in my 2016 Outlook configured on the same Exchange server system.
I"m going to reset my Windows OS so I'll make the necessary registry change as soon as the reset is completed. I need to know the best way to back up all these email accounts before I do the OS reset and then put them back in Outlook 2016 once the reset is complete and the registry change has been made.
Can I do an Acronis 2018 full backup of the OS on the newly installed drive and then just use only the Office 365 part of the backup to put on my new drive? Is that possible? Can I use Acronis 2018 to back up only Office 365? If I am able to do either of these procedures will the backup of Office 365 also contain all my email accounts' existing messages and folders in Outlook 2016? Would I have to back up and then transfer other files or folders, such as in the App Data folders, before a backup of Office 365 would allow all my email accounts to function properly, or will I have to settle for backing up Outlook 2016 to a location on my secondary internal drive using .ost/.pst files?
Please excuse my ignorance. I've spent a great amount of time researching this issue and I still haven't arrived at a definitive conclusion. I never ask others for assistance unless and until I've put substantial research into the issue in question and come up empty handed because I don't think it's fair to ask others to do my work for me and because they willingly give up valuable time with their families to assist others in need. A Windows reset and a new installation of Office 365 is probably the way to go but I DO NOT want to again configure 27 email accounts.
Thank you in advance for your time and any assistance provided.
