Local domain mailbox migration error
I ran into an issue while migrating from on-premise to O365. On-premise AD domain is “domain.local” so users have their mailboxes smtp address as follows: primary smtp mailto:email address removed ...
It's only added by default becasue you have the .local address in your email address policy. Update the email address policy to remove the .local address, then you'll need to run a script to remove the .local address as an alias from all existing accounts (removing the .local address from the address policy will not remove it from existing objects, it just means any new objects will not have the .local address).
that's correct, I know that it's the default policy managing the domain.local address and that I can remove it to solve the issue.
My point is that in all other situations where I had the same configuration, I did not have such issue while migrating mailboxes to O365 in hybrid environment and cannot understand it
