Convert resource mailbox to cloud only
LeonPavesic will this recreate the old mailbox with all current bookings or will there be a completely new empty mailbox?
Thanks

Hi PSonander,
thanks for the update.
no, recreating the mailbox as a cloud-only mailbox will create a completely new and empty mailbox. This means that any existing data, such as previous bookings and emails, will not be automatically transferred to the new mailbox. You will need to manually migrate or re-enter the existing data and bookings into the new cloud-only mailbox.

Hi,
"no, recreating the mailbox as a cloud-only mailbox will create a completely new and empty mailbox. "
=> this is then not a conversion. This is a recreation.
- PSonanderNov 01, 2023Copper ContributorI see, my question was how to convert a resource mailbox to be cloud only, not how to create a new resource mailbox. I need a solution to convert it without loosing all data in the mailbox

PSonanderDid you find a solution to this? We want to move all of our resource and shared mailboxes to M365 only (that is, no longer dependent on an on-prem AD account existing). Finding accurate information on how to do that is proving challenging.

shawnsarnia no I have not found any supported way of doing it.
What I have done in some cases is to remove the onprem AD account from the scope of the EntraID Connect, effectively deleting the account in EntraID. Then doing a restore from EntraID side. This has worked but is as far as I know not supported by Microsoft
