Here’s another trick that is really very simple, but, for reasons I can’t figure out, difficult to find out about. Despite what the documentation seems to say (and despite what I have read MS employees categorically stating), you CAN add an Exchange mailbox to an account that already exists in AD.<\/span><\/span><\/p>\n

Bundled with MIIS are various programming extensions we make use of, including the <\/span>ExchangeUtils<\/span><\/a>. This collection of methods simplifies the creation of Exchange users, contacts and distribution lists – but like all these things it has its own quirks and apparent oversights.<\/span><\/span> <\/span><\/p>\n

You may well think, on first glance, that ExchangeUtils.CreateMailEnabledUser would create a User+Mailbox, and ExchangeUtils.CreateMailbox would just create a mailbox, however this is not the case. If you want to create a User+Mailbox then what you need is actually ExchangeUtils.CreateMailbox. Don’t ask me what ExchangeUtils.CreateMailEnabledUser is for – I never did find a use for it.<\/span><\/span> <\/span><\/p>\n

So, if you just need to create brand new users, complete with mailbox, then you’re set – use ExchangeUtils.CreateMailbox in your provisioning code, as per the examples in the Developers Reference.<\/span><\/span> <\/span><\/p>\n

BUT this isn’t always enough. There are plenty of cases where you may want to add a mailbox to an existing user account. You don’t want to create a new one, because then the poor ole user will lose her password and profile. Happily it is perfectly possible to do, you just use the export flow rules in your MAExtension to set the following values:<\/span><\/span><\/span><\/span><\/p>\n
