Preparing to migrate from SBS 2003 to WSS 2012 R2. This site is already on Office 365 so we will be integrating that. From http://technet.microsoft.com/en-us/library/jj713507.aspx#BKMK_Access3
"Passwords cannot contain the user name or email address.
If you integrate with Office 365, the integration enforces the Strong password policy, and updates the policy to include the following requirements:
◦ Passwords must contain 8–16 characters.
◦ Passwords cannot contain a space or the Office 365 email name."
The existing users login accounts and Office 365 accounts do not conform to the strong policy, just the minimum 8 characters and do not contain the email name. So, will the users be required to change their password when they log into the new server, after the migration? I would assume then that their Office 365 password will also have to change. It's unclear whether I can change that policy. I just need to know if users should change their passwords on the server and Office 365 before the migration.
