It's not uncommon to have multiple outlook accounts (to keep work and personal accounts separate). Having the ability to sign into multiple accounts at the same time would be great. There are third party apps that offer this already (Cloud Indeed, File Hub, etc).
As a consultant, i work with different clients and need to keep different accounts separate and in sync.
The sync client is still limited to one personal account and one work account. I fail to see the logic behind that decision, there's no reason not to allow multiple accounts

Yes, my husband and I share the laptop, so it would be good if we could both use drag and drop, rather than sign in online.
