E-mail addresses are created incorrectly if an e-mail address policy in Exchange Server 2007 contains certain symbols, a slash or a backslash, and then another of these symbols

Consider the following scenario in Microsoft Exchange Server 2007. In Exchange Management Console, you define an e-mail address policy under E-mail Address Policies in Hub Transport under Organization Configuration. The e-mail address policy contains one of the following variables:

• %g
• %i
• %s
• %m
• %xs
• %xg

Immediately after one of these variables, the policy contains a slash (/) or a backlash (\). If an e-mail address policy contains another one of these variables immediately after the slash or the backslash, the e-mail address policy creates e-mail addresses that are incorrect.

Note Other variables may also cause the e-mail addresses to be created incorrectly.

For example, you may experience this issue when you use the following e-mail address policy for IBM Lotus Notes: When you use this policy, you expect the following result:

NOTES:Joe Bloggs/JBloggs/Contoso@Exchange

However, you receive the following result:

NOTES:Joe Bloggs/%m/Contoso@Exchange

Microsoft Exchange Server 2007 does not replace symbols after the first slash, backslash or "at" sign characters in e-mail address policies. The resulting e-mail address still contains the symbols, %g, %g, %i, %s, %d, %m, %xs, and %g.

To resolve this problem, install the following update rollup:
After you apply this update rollup, everything before the domain separator is processed by the proxy address generator.

Note The domain separator is the final instance of the at sign (@) in the group e-mail address policy.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Exchange Server 2007 does not interpret these variables as case-sensitive. To support legacy configurations, these variables may have the percent (%) prefix or the ampersand (&) prefix.

Note In modern configurations, the percent prefix together with lowercase text is preferred.
