There are 3000 or so mailboxes with aliases that are all over the place. Some have spaces, some have invalid characters which won't work in 2010, some are firstname lastname, some are samaccountname, etc.
I am planning to clean these up so that:
- They are 2010 compatible (moving from 2003) so spaces and invalid characters need to be removed (I have a script to do this so that they can actually move to 2010 in the first place!)
- As a second task, try to get some unity between the aliases when we move them across so going forward all accounts are the same format
What are the possible gotchas for changing the mail alias attribute? The recipient policies are based off firstname.lastname and do not reference the alias, so that is the main point covered, but I want to check if people have come across anything else?
I am looking at moving to having the alias match the SAMAccountName attribute so that there are no issues with POP3 or IMAP mailboxes, so what will the end user see? Clients are 2003 and 2010. Currently Exchange 2003 going to 2010.
