Migrate mailbox to another domain same Tenant
Hi, In our company, we bought a new domain and we want to move all of our existing mailboxes to the new one. I already have both domains registered in the same tenant. I mean support@contoso.com to support@contosola.com etc. May you please give me any advice on the best way to perform this?
Same alias, multiple domains, different mailboxes
I'm looking for how to set up shared mailboxes such that I have email address removed for privacy reasons, email address removed for privacy reasons, and email address removed for privacy reasons on different shared mailboxes. 365 Admin Center won't let me. Exchange Admin Center lets me, but then it doesn't actually work.email forwarding failed in DMARC
My primary office Corp is using Exchange online and we acquired another company with exchange online as well. In the new company tenant, the mailboxes were converted to shared mailboxes with email forwarding to CORP. Some of the emails fail to be delivered because of DMARC.The error is 550 5.7.509 DMARC verification fails. In CORP we have v=DMARC1; p=quarantine; pct=100; Does anyone have any suggestion?
