Create shared mailbox on Hybrid environment - directly on O365 or onpremises then migrate it to O365
Hi, What is the recommended way to create shared mailboxes for a hybrid environment? There are some issues if you create them directly to O365 - https://support.microsoft.com/en-us/help/3129334/u...
Hi Carlos,
If you have an Hybrid, your autodiscover is pointing to your on-premises Exchange. If you create your Mailbox only in Cloud, your AD and Exchange does not have any propreties of that mailbox, that is the issue.
I currently:
- Create an AD account in a OU that syncs with 365.
- On my on-prem exchange, run a powershell command:
enable-remotemailbox <name> -remoteroutingaddress <mailbox>@<company>.onmicrosoft.com - Once 365 has synced, change the mailbox to shared.
- Back in Active Directory I change the attribute msExchRecipientTypeDetails to 34359738368 and msExchRemoteRecipientType to 100
- Going to try this now. Looks like this is what I do for new users. step 3 and 4 is what I was needing to know for new shared mailboxes.
- Hi Fermin
Did you try this method? Did it work? We're looking to find the same answer. Thanks!
Thanks for these instructions.
Used them when I already had the shared mailbox created on the cloud and synced to on-premises AD.
Just ran the powershell command in the exchange console, changed the attributes and ran a delta sync cycle.
