XADM: Update DLs When Their Expansion Server is Moved

SUMMARY

If you have distribution lists (DLs) defined for a site, and the expansion server for those distribution lists is moved out of the site, you need to specify a new expansion server for those distribution lists. The distribution lists continue to work, but the lists cannot be modified until the expansion server value is updated.

To update the expansion server value:

1. In the Exchange Server Administrator program, click Site, then Recipients, and select the distribution list.
2. From the File menu, choose Properties.
3. On the General tab, select a new value in the Expansion Server list, and then click Apply.
