What triggers mail flow issues?

The first thing to do is find out the reasons for such an issue. You can check what has changed in the current server setup. The best idea is to always keep a log of who had and what was changed. This way, if there would be a configuration issue, it’s easy to trace back and roll back any changes to identify the issue. Mail flow issue can be triggered after migration to a newer Exchange Server or due to a problem during an update of Exchange Server after installing a Cumulative Update (CU).

IdFix – Directory synchronization error remediation tool

IdFix is used to perform discovery and remediation of identity objects and their attributes in an on-premises Active Directory environment in preparation for migration to Azure Active Directory. IdFix is intended for the Active Directory administrators responsible for directory synchronization with Azure Active Directory.

The Microsoft Office 365 IdFix tool allows you to identify and remediate object errors in the Active Directory in preparation for deployment to Azure Active Directory or Office 365. You can then successfully synchronize users, contacts, and groups from the on-premises Active Directory into Azure Active Directory.
