hi joe,

 

i may need more details below:

1. by “hybrid environment active directory , exchange in office 365”, mean there in-premises exchange server? have deployed exchange hybrid?
2. are using aad connect sync tool?
3. is distribution list created on-premises active directory , synced office 365?
4. is there error message when add shared mailbox distribution list?

 

actually, needn’t assign more permissions. if distribution list synced on-premises active directory office 365, cannot edit members in office 365. need add members on-premises active directory , sync them office365.

i suggest try following methods achieve goal:

method 1: can re-create on-premises user , match him/her shared mailbox referring article:

method2: delete shared mailbox> create new ad user> sync him/her office 365> assign license> convert shared mailbox.

 

if above cannot meet requirement, please provide detailed environment information , detailed steps on how create shared mailbox , distribution list.

 

best regards,

vanessa
