Is the ampersand character a valid character for an Exchange email address?

Question

I am trying to find out if the ampersand character "&" is a valid character for a Microsoft Exchange email address. I know this is true according to the RFC, but I think the exchange has a subset of valid characters.

Example:

Tom & [e-mail]

Answer 1

Yes, Exchange will handle them.

However, they pay special attention when creating links on pages and other things that require email encoding so that Outlook and other clients understand what you intend. It is probably best to avoid using them if possible.
