We are having issues where many of our Outlook Web App users are unable to reset their passwords within OWA. (Options -> General -> My Account -> Change your password). When they try they receive the windows where they are able to type in the new password, but when they choose “Save” they get the following error:
"There was a problem saving your changes. Please try again. If the problem continues, contact support".
It has nothing to do with password security or password history as those give the correct error: "The password you entered doesn’t meet the minimum security requirements”. And it is not affecting all users - for example I was able to change my password using that feature, but the majority of users cannot.
We are using on-prem Exchange Server 2016, Version 15.1, build 1913.5 on Windows 2016 servers, build 14393.3474. We have three servers.
I tried some experiments to see if anything would allow a password change:
- Users are able to change their password if passwords have expired and the user is prompted on the home page of OWA.
- I am able to change the password for a test account on one of the Exchange servers using https://localhost/owa and then Options -> General -> My Account -> Change your password.
- I am able to change the password for a test account in a browser using the public IP address for OWA in place of our URL, i.e. https://xxx.xxx.xxx.xxx/owa versus https://domainname/owa
These same test accounts threw the error when using the URL. I do not see anything in the event logs.
This is a huge concern for us as about two thirds of our users primarily use OWA and would prefer to change their passwords before they expire. I don’t know if this is an Exchange error or an IIS error or even a certificate error. The certificate is current and was renewed recently (November 2019).
I opened a support case 2 days ago with Microsoft and have not received a response (different issue). Does anyone have any ideas?
