I need to migrate < 35 email accounts from a hosted Microsoft exchange service. Specificaly that offered by iiNet. When I read the variouse migration options it never seems to refer to such a senario only on premises and hybrid models.
With the hosted exchange service I seem to have a limited access to the actual exchange server presumably because it is a multi-tenent service.
I have my users already in Office 365 with there primary address now firstname.lastname@mydomain.com (rather than firstname@mydomain.com) and whilst I need a form of cutover migration because I need to redirect the mx record I can see with limited user numbers all I need is a way to migrate existing emails, contacts into the new accounts.
I seem to have run down a lot of rabit holes trying to find the best or even a way to do this.
Has anyone done something similar and can you share the basic outline of how you proceeded?
