Errors Office 365 Troubleshooting UnitySync
UnitySync v2.3 and greater supports syncs to and from Office 365 (O365).
There are two possible causes of an Access Denied message.
UnitySync configured via IIS
If you are using Internet Information Services (IIS) to access the UnitySync User Interface (UI), and you have an Office 365 connection, you may receive an access denied error message when testing or running the connection.
If this occurs, go to IIS > Authentication > Edit Anonymous Authentication . Select ‘Application Pool Identity’ and click OK.
In UnitySync versions 3.0 and older, and regardless of how you access the UnitySync UI, you may still receive an Access Denied error because those versions utilize powershell to connect via basic auth. If your O365 tenant has disabled basic auth, you will not be able to connect. Please contact firstname.lastname@example.org to upgrade to the latest version or re-enable basic auth.
