Great idea!
Main account (receiver) had about 400 GB or so?
Secondary accounts (sharer) had about 600 GB and maybe 200 GB? I don't remember the exact figures but I would say my total was below 2 TB total, around 1.5 ~ 1.8 TB total.
I am logged on my computer about 16 hours everyday, 7 days a week, almost always with OneDrive on line.
I don't think there's a single day when I don't at least make changes to files stored there or add new ones.
I also use other devices like a printer and my phone / camera.
I only use MS office on one computer, actively. Only Excel and MS Access probably between once a month or even once per quarter.
I rarely use anything else. Had those 60 skype minutes but it was always so cumbersome and there's so many restrictions on where we could use them that I ended up wasting 99.9999% of them.
Dislike Teams, used Outlook to fetch all my irrelevant mail boxes. Was surprised they removed that service when I noticed those messages weren't coming when I used the "isread:no" filter to check what was new across my entire storage.
Stopped using my shares once they broke, obviously, but not only because they broke but I was forced to change my workflow. My "cold case files" still need to be resynchronized properly, my main account now holds most of the files.
I might be too lazy to move to another solution soon enough and there's a chance I pay them 109 CAD this year just so I have more time to adjust. Renovation bill in a month.
Only main account stuck on V1. Others migrated.
Does it help?
