These are from the EWS but could you check them for the OWA and ECP directories?
And do they match with IIS?
Also, could you recycle the IIS sites?

On which server is the mailbox of the admin account homed?
If it's placed on the Exchange 2010 server then it could be possible that Autodiscover or the back end virtual directory is not functioning properly.- Navishkar SadheoJun 08, 2020Steel Contributor
"It's also strange that onboarding didn't work properly, I would advice you to use the Office 365 ECP (outlook.office365.com/ecp) to create migration batches as the ECP within Exchange doesn't work properly sometimes (experienced this myself as well)." --- About this.....so what happened was that Exchange online wasn't able to connect to the migration endpoint. The only time it was able to connect was when I change the authentication options on those virtual directories.

Aaah I have been dealing with this a lot lately, this is because for some reason the EWS directory isn't accessible through basic auth.
You can resolve this with the following PowerShell commands:
get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -MRSproxyenabled $false
get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -basicauthentication $true
get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -MRSproxyenabled $true
EWS is used by Office 365 to process mailbox onboarding.
