Hello, I install Skype for Business 2019 without realizing it did not offer the persistent chat feature like 2015. I started off by uninstalling the skype for business 2019 by using https://learn.microsoft.com/en-us/skypeforbusiness/hybrid/decommission-remove-on-prem. But when I went to install the skype for business 2015. I get the following error
"00000057: LDAP: DSID-0C0910DA comment: error in attribute conversation operation, data 0, v4563
Any help would be great.

Do you have any operations before this issue occurred?
Did you create the AD User before install SFB Server 2015?
According to your error message, this issue is happened in your Active Directory attribute. If one of the attributes being copied has a null value, it will also pop out this error message, so it recommends you try to check each attribute to confirm which one is empty.

2022-05-10T17:15:34.14+00:00 Hi Jimmy, and yes with the Skype for Business 2019 I it was installed successfully and working. It wasn't until I uninstalled 2019 and tried to go to 2015. Which object on do I check the attributes.?
When i go to reinstall 2015. The Schema is completed. When I try to prepare the Active Directory Forest it gives me this error.

Is it permissions or an attribute?

2022-05-13T09:31:16.983+00:00 Hi @Brian Moody
The Prepare Current Forest (steps 3 and 4) requires Enterprise Admins privileges, and in this step the Skype for Business Server groups will be created in Active Directory (they all start with CS or RTC on their names).

Sorry for the delay response!
Do I need to create the accounts manually.
No, you don't need. You just make sure the account you login in Skype for Business deployment wizard have the enterprise admin rights.
Where can i find exactly what the prepare schema, prepare AdForest, and preAdDomain.
All of the each steps you could see it in this page.

2022-05-24T16:58:41.747+00:00 Ok I went through all the schema attributes one by one and noticed that all msRTCSIP-Applicaton attributes was in a defunct state. I set the defunct attributes to false to turn them back on.
But now i am getting another error.

2022-06-14T01:37:40.067+00:00 Sorry for the delay. I have been out in the field.
Yes I had to go through all the ADSI (schema) attributes one by one. And realized that all the application attributes was turned off. Once i turned them back on. It installed perfectly. I got persistent chat working as well.
One minor problem now. Once you get logged into skype. A little warning box pops up stating exchange needs my credentials again.
How do I get that off of my skype?
