change exchange 2010 multi tenant to exchange online
Posted on 2016-08-24
We have our own exchange 2010 sp1 multi tenant environment where we want to move a client from our exchange to exchange online.
Everything goes well outside the domain, but within the domain, were the current exchange server still resided and their (old) mailbox, i have to manually add the mailbox settings, because autodiscover does not work, i think because there is a autodiscover setting in the dns.
Problem: every time when i add a new profile and add the new exchange server manually, with all the setttings, after a logoff and logon the settings are overwritten and the mailbox has become the old mailbox (exchange 2010 sp1) in stead of the new Exchange online one,
