Kerberos ASA - Change Encryption Types

Hello,

We have Exchange running for many years now with an ASA account. Now we found out that our ASA only supports RC4 encryption.

This is the reason: https://docs.microsoft.com/en-us/Exchange/architecture/client-access/kerberos-auth-for-load-balanced-client-Access

When we created the ASA User Account we didn´t changed the Supported Encryption Types.

The question is now: Can we change this during normal business hours without any impact, or will it need a IIS reset or something like this to get active?!? Unfortunately I am unable to test it somewhere and changing this later is nowhere documented - at least I was unable to find it...

Thanks a lot for Your help!
