Quest On Demand - Cannot set delegate Failed to add one or more delegates


T2T Migration + AD (Source) -->AD (Target) Migration Using QMM

Source = Hybrid O365 / Exchange

Target = AD with Exchange Management Only (No Hybrid)


After successful Migration of Mail data, Setting the the Delegates fail with erro Cannot set delegate  Failed to add one or more delegates. All objects Matched ok


This is caused if the source domain is in "Hybrid" in which the "publicdelegates" attributes get written back to the On-Prem AD, In turn this is migrated to the Target AD, That is NOT in hybrid mode.

This then stops the public delegates getting written in O365 as its populated with data from on-prem AD.


Clear the "Publicdelegates" attribute and exclude from QMM DirSync. and re-run
