When you are first invited to a Collaborate site, you are invited with your email address and your email address becomes your username for logging in. Sometimes, the email address that was selected may not be your preferred email address. This happens in many situations, including:
- Where a company supports multiple email prefixes (for example, jsmith@acme.com and john.smith@acme.com), that are aliases for the same person
- Where a company supports many regional and one global email domains (for example, @us.acme.com and @europe.acme.com, and @acme.com), where the same person may have email accounts with different domains
- Where a company has multiple regular email domains (for example, @acme.com and @acme-corp.com) and the same user may have email accounts with different domains
Additionally, you may need to change your email address if your company changes the email prefix format (for example, from jsmith@ to john.smith@) or changes the company's email domain (for example, from @acme.com to @i-acme.com). It is also possible that you move to a different company but still require access to your existing Collaborate account. For example, a lawyer at one firm working on a transaction switches to another firm, but still represents the same party to that transaction.
Changing your email prefix (user)
You cannot change your own email prefix (from, say, "jsmith@" to "john.smith@"). Contact your Site or System Administrator to change your email prefix.
Changing your email suffix (domain)
You can change your own email suffix, but this is subject to certain limitations. As long as you are associated with a certain organisation in Collaborate, you may use email domains associated with that organisation. A drop-down menu in the Email address field of your profile shows available email domains:

You may select any one of the domains available for your organisation. If the domain that you want to use is not listed, you, or a System Administrator, must contact the host of the Collaborate instance and request an additional email domain.
Changing your organisation
You may need to change your entire email address because, for example, you are switching companies but still need access to Collaborate. This type of change must be approved by the firm that is hosting the Collaborate instance; contact them, or your System Administrator, to ask them to approve and make the change.
Making a change on behalf of a user
A System Administrator at the hosting firm can access your profile and make any of the above changes. If you are having problems changing your email address, contact the firm hosting the Collaborate instance to make the change on your behalf.
