Exch 2016 adding hybrid

[Jim Kennedy]

 

I am helping the school district add hybrid exchange to the existing on-prem 2016 system. Hit a snag, the default email policy is legacy, from 2003. So it errors if I try and upgrade it, because that has to be done from the same MMC it was created. No big deal, make a new one and make it the default is what I figured. I created a new one, but I can’t see or google a way to make it the default policy…so that I can delete the legacy policy which the hybrid configuration wizard insists I upgrade.

 

And for the record, the old x400 addresses from 2003 can be deleted/ignored right?

I should add, the current ‘default profile’ is showing as unapplied. The new profile has been applied.

Will it let you simply delete the legacy one or does that throw up an error also?

(sorry, it's been a long time since I've seen a 2003 policy)

No, delete is grayed out on it. That legacy version is still set as the default.

I was going to suggest just deleting the policy (which I’m pretty sure I’ve done more than once) and set the priority or order field on the new policy appropriately.

 

But the Perficient guy’s blog looks good.

For the record, the ADSI edit worked fine. Took out the old mailbox manager settings and we were good.
