We have acquired a company and need to integrate our email. Our company is utilizing Office 365, while Company B is utilizing some other hosted email provider.
We understand how to migrate Company B from their hosted email provider to Office 365, but we don’t understand whether we need to add them to the Company A email domain or keep the Company B email domain in light of the following criteria:
- Give everyone in Company B a default Company A email address, so all internal communications (and some external communications) are done via Company A email addresses and allow sharing of calendars.
- Give everyone in Company B the ability to still send & receive email to their customer base as their Company B email address on an as needed basis. Can this be done via aliases somehow?
In time only use the Company A email domain after the integration of the two companies has been fully socialized and accepted in the industry.
Company B is also using hosted Sharepoint, while Company A is not. How can this be migrated to Office 365?
