I just received a message to Link my Google Drive and Dropbox to OneDrive

Is OneDrive sending out messages to link your Google Drive and Dropbox to your OneDrive Account? I did follow this to link both of these to OneDrive and I checked my permissions and it said in Google Drive that it was linked account but the name was mover.io (I have never heard of them) is this legit ? I got a whole lot of emails from Google and Dropbox about linking to my OneDrive but not one from MS OneDrive. So I am suspicious this was a legit request. Mover.io is the name in One Drive but I cannot see anything in my OneDrive that says "Google or Dropbox import. All I saw was imported folder but when I open it up it has my Dropbox email address ending in gmail.com - Dropbox. So I am assuming this is all above board and I wasn't a victim of some scammer.

How do I go about linking this myself so I know it 100% kosher? I have at present unlinked both cloud services with my OneDrive which has a larger capacity of 1.25gb storage than my Google drive and Dropbox.

Mover.io is a specialized cloud-to-cloud management app aimed at helping users migrate their cloud files to Office 365. It is part of Sharepoint and is legit.. Is that what you wanted to do...move everything from dropbox and google drive to onedrive? Did you purchase the Microsoft 365 SharePoint Plan 3 which starts at $23/month per user. If I understand it correctly that plan is is mostly used by businesses. One of the big ondedrive users here can probably explain it better.
