XADM: Rehoming Public Folders Adds Number to the End of the SMTP Address (254349)

SUMMARY

When you rehome a public folder between two sites that share the same address space (for example, microsoft.com), the directory object that represents that folder exists in two places for a brief period of time.

When this duplication occurs, the Simple Mail Transfer Protocol (SMTP) address on the destination server has a number added to the end of the SMTP address prefix. For example, "PublicFolder@microsoft.com" becomes "PublicFolder2@microsoft.com."

MORE INFORMATION

A duplication of the directory object that represents the public folder on the source server occurs in the Recipients container (or the default public folder container designated on the General tab of the Site Information Store Configuration object) of the destination site. The original object and the new object coexist in the directory for the period of time that it takes to complete replication. The change in the SMTP address of the public folder occurs because the design of the Exchange Server directory prevents duplication of addresses within an organization.

After you rehome the public folder and inter-site replication removes the original SMTP address from the directory of the organization, you must manually change the SMTP address of the folder back to the correct address.

For example, if a folder named "faxes" exists in the Dallas site with an SMTP address of "faxes@microsoft.com," and you rehome it to the Atlanta site, the SMTP address of the folder becomes "faxes2@microsoft.com."

However, if the two sites had SMTP suffixes (which is the Exchange default) such as "atlanta.microsoft.com" and "dallas.microsoft.com," this would not be a consideration.
