delete old exchange scp record using asdi edit

i have already migrated to office 365. when i turn on the old exchange 2010 server the outlook 2016 clients connect to it instead of office 365. i think i need to do this? i am trying to turn it back on so i can do a graceful uninstall of exchange 2010.

You can delete the SCP record altogether using ASDI edit:

Select the “Configuration” naming context
Drill down to:
CN=Services\
CN=Microsoft Exchange\
CN=<Your Org name>\
CN=Administrative Groups\
CN=Exchange Administrative Groups\
CN=Servers\
CN=<Your Server Name>\
CN=Protcols\
CN=Autodiscover\
And delete the CN=<Your Server Name> of class serviceConnectionPoint in there

i guess i am trying to confirm that this will prevent the outlook clients from trying to get the mailbox from exchange 2010, and they will continue to connect to office 365 when i turn the exchange server back on. is that right?

for all CAS servers you can delete SCP by below cmdlet in one shot

Get-ClientAccessServer | Set-ClientAccessServer -AutodiscoverInternalURI $null

Open in new window


OR

Set-ClientAccessServer -Identity CAS01 -AutodiscoverInternalURI $null

Open in new window

If you wanted to do one by one

by the way, you need to set CAS SCP URL to Null instead of deleting SCP object from AD, as a correct method
