Prospective MS 365 Business Basic buyer has some questions.

<p><strong><em><u>Will there be any issue buying the above plan with a pre-existing MS account registered with an email address of the current domain I want to move over?</u></em></strong></p><p class="ql-indent-1"><br></p><p class="ql-indent-1">So here's the confusing part to understand, but we'll go through with with examples.</p><p class="ql-indent-1"><br></p><p class="ql-indent-1">When you login to anything Microsoft related, you will be asked two options, <strong>Personal </strong>or <strong>Work</strong>. </p><p class="ql-indent-1"><br></p><p class="ql-indent-1"><strong>Personal </strong>will take you to the MS account services, which after the transition will mainly be for Xbox and perhaps Teams for Friends and Family (when ever that sorts itself out)</p><p class="ql-indent-1"><br></p><p class="ql-indent-1"><strong>Work </strong>will take you to your M365 Business services, this is the option you would always select. The URL is usually <strong>*.office.com, </strong>so services like outlook will be <strong>outlook.office.com</strong>, I personally always go to <strong>portal.office.com</strong> to avoid any confusion from Personal and Work versions of M365.</p><p class="ql-indent-1"><br></p><p class="ql-indent-1">Secondly, you will need to update your <strong>MX</strong> records, this will tell your domain host to send all new emails to the M365 Business <span style="color: rgb(0, 0, 0);"> </span><strong style="color: rgb(0, 0, 0);">outlook.office.com </strong>inbox instead of the MS account <strong style="color: rgb(0, 0, 0);">outlook.com </strong><span style="color: rgb(0, 0, 0);">inbox.</span></p><p><br></p><p><strong><em><u>Can I add additional custom domains later, without buying additional Exchange mailboxes?</u></em></strong></p><p><br></p><p class="ql-indent-1">Yes, you can. You can set aliases as well for the same account, for example I have a <strong>.works</strong> domain for my main business account, some third party service don't like <strong>.works</strong> as a valid domain.</p><p class="ql-indent-1"><br></p><p class="ql-indent-1">So I have added a <strong>.com</strong> domain as well to the same account and created an alias for myself, so people can email with both, the <strong>.works</strong> and<strong> .com</strong> email addresses. </p><p class="ql-indent-1"><br></p><p class="ql-indent-1">Also remember that you need to update the MX record for these domains. All of this is in guided steps from the M365 Admin center.</p><p class="ql-indent-1"><br></p><p class="ql-indent-1">You can set up shared mailboxes, so these are just email boxes, they don't have other M365 features but they are just email inboxes that you can access that are separate from your account, that also doesn't need any additional licenses. </p><p class="ql-indent-1"><br></p><p class="ql-indent-1">I've done the same, I've created <strong>purchases@, twitter@, ebay@ etc,</strong> shared mailboxes, and so all those emails go to those inboxes instead of mine.</p><p class="ql-indent-1"><br></p><p class="ql-indent-1">These have no additional cost, and also you can send from those email addresses as well.</p><p><br></p><p><strong style="color: rgb(0, 0, 0);"><em><u>Do I get any useful import tools to easily move my email, calendar, reminders, tasks, and contacts over from Google Workspace?</u></em></strong></p><p><br></p><p class="ql-indent-1">In the admin center you can use the built in migration process to migrate from GSuite, Gmail, other M365 / Exchange, outlook.com and other services as well.</p>
