Migrating On-Prem Distribution Groups to Exchange Online in Hybrid Mode
Jerryn Bunnell I don't know how you have things set up but generally speaking cloud objects do synchronize back to on-premises AD.
I was reading an article when searching how to do this and it claimed if you went to office 365 exchange admin, went to groups and in the upper right clicked on upgrade distribution lists it would let you move them however when I click there it doesn't show any of my on prem DLs.
Boe Dillard Synced from AD are not eligible. They have to be copied to the cloud and deleted onprem.
djreit I am going to try your method and see if this works for me. I'm at the same spot as everyone else on this thread. Please don't let this die. This is more involved than it seems. Sorry, I'm a newbie when it comes to MS Exchange so I'm learning this on the fly.
We are in a hybrid set up. Trying to take existing DLs on our on-prem environment to O365. While we aren't doing away with our on-prem environment any time soon, DLs must be in the cloud soon so users can have the ability to manage them again as they did prior.
Anything learned since the last post is greatly appreciated.
Reading through the posts here is some short code as I understand the process of migrating an OnPrem DL to a Cloud DL:
OnPrem
1. Get the x500 LegacyExchangeDN from the DL
2. Get the members of the DL
3. Remove the DL
Cloud
1. Create the DL
2. Add Members to the DL
3. Add Alias x500 equal to the LegacyExchangeDN from above
TonyRedmond Thanks - that is the article I was looking at. I opened a case with MS but he got distracted by something else. He seemed to think since it was synced I shouldn't worry about it which might be valid but I'm trying to avoid the day that their exchange server stops working and it depends on anything that is on prem. I'll open another case.
I did get this command to find out if it is Mastered on Premise or hosted in office 365
get-recipient -identity dlname@yourdomain.com |FL
The ones I'm upgraded are groups I created in Exchange. I wonder if those eligible ones (ones I don't see any of) are ones people created in their outlook.
thanks, it may be something like that. There aren't any nested members but as you say there might be something about them. I created a new group about an hour ago, it just had 2 names in it but it wouldn't let me migrate it. I'll ask MS to see if they can figure it out.
Boe Dillard Your DLs might not meet the criteria for conversion. For example, if they have any nested members, you can't convert the DLs with EAC.
