Outlook failing to update profile after cross-forest migration

I am doing cross forest (Exchange 2013 to 2016) migration.

I have 2 forest abc.lan (Ex 2013) and 123.lan (Ex 2016).

For exchange 2013, Some of the users currently use outlook within domain (their computers are domain joined to abc.lan).

For  outside domain migrated users, all is good, they get standard message to restart outlook, and their profile get updated after restart automatically using Autodiscover record pointed to Exchange 2016 server.

But, I am getting problems with outlook machines joined to source server AD domain.

After migrating, I am getting the standard message that 'Microsoft Exchange administrator has made a change that requires you quit and restart Outlook', and when I restart outlook, After few minutes, outlook throws following error:



Can anyone suggest a solution for this problem.

Thanks in Advance.
