Hello Community,

Please I need your help on this.

On-prem Skype for Business (SFB) asking for exchange credentials continuously post enabling MFA in O365

After we set up the MFA then the issue started with SFB On-Premises.

I have tried using the APP password, but it didn’t work. Our Exchange Server is hosted online
