Clash of MAM on Same Tenant with multiple domains
Hi,
I have a single O365 tenant with a number of domains on.
Lets call domain 1 mailto:martin@Dominion.com and domain 2 martinmailto:martin@dominion.business
Both domains are registered with O365 and each has its own mailbox for separation/purpose,
I have MAM and MDM setup, using Apple devices with Azure MDM connectors/tokens / VPP/App Store etc federation to Apple Business Manager of the necessary domains all in place etc) working.
I can add the first domain to the iOS Outlook client no problem, but, when I try to add mailto:accounts@dominion.business I get the error message
"Your admin wants the apps on this device to managed with the account 'martin@dominion.com'. The app account you are using 'martin@dominion.business' will be removed. To access your organisation's data with the account 'martin@dominion.business', you must unenroll your device from the company portal."
But its the same portal, O365 tenant. MDM/MAM and AD??
Am I missing something obvious here!!??

It's not possible to add to MAM-protected mailboxes on the same device, even if they are from the same tenant. Microsoft is aware of this issue.
The current workaround you could do is give mailbox A full access to mailbox B.
Then log into Outlook with mailbox A and add mailbox B as a shared mailbox.

Unfortunately, this did not work... Still get the error message about management...
- A management profile might still be stored somewhere. Try deleting Outlook and the company portal and try again
