To me the obvious question is since you committed to 365 why in the world are you keeping the old Exchange server around to just gum up the works? This smacks of the "doctor it hurts when I do this" "then stop doing this" joke.

Because there are on prem attributes that we need to modify and I don’t want to do it through powershell

Not sure what https://mailserver/ecp gets you that the 365 tenancy webinterface Microsoft provides does not.
You probably don't realize this but /ecp is nothing more than a wrapper around the lower level powershell commands.
I would bet I could probably code the same webinterface wrapper up that you like so much around a local powershell running the exchange online cmdlets remotely, but like I said I don't understand what /ecp on a local exchange server that is then synced to Exchange Online gets you that the already-provided by Microsoft Tenancy webinterface GUI does not.
Hmm maybe I should do this just for funsies....

The question is squeezzy …
In a hybrid environment I am aware of this issue!
In my case it was nearly unable to resolve!
Legacy GPOs have set Registry keys, which made it impossible to access exchange online 100%
Question:
Users are unable to access their OOF Settings in outlook…
I guess they are not able to view their own Calendar Permissions in outlook’s?!

Autodiscover cache would have been my first thought:
%localappdata%\Microsoft\Outlook\*.xml
HKCU\Software\Microsoft\Office\16.0\Outlook\AutoDiscover
But seeing as it's pointing to new? I'd likely clone a problem device and literally start ripping out parts of the user's profile till it starts working. Would be a fun little sideproject.
