We have the following environment:
Company A Forest companya.com Exchange 2010 SP3 (SMTP domain companya.com)
Company B Forest companyx.com Exchange 2010 SP3 (SMTP domain companyb.com)
I am thinking of using multi-forest hybrid migration to 1x O365 tenant.
However, I saw somewhere on the Internet that Exchange 2010 does not seem to be supported in this scenario.
Can someone please confirm this for me?
Thanks in advance.
