Hi Norah,
Here is the output of Powershell when we have a bad object. This lists the valid characters for an object.
WARNING: Object nce12.org/DragonsRest/dragon49 has been corrupted and it is in an inconsistent state. The following
validation errors have been encountered:
WARNING: "dragon 49" is not valid for Alias. Valid values are: Strings formed with characters from a to z (uppercase or
lowercase), digits from 0 to 9, !, #, $, %, &, ', *, +, -, /, =, ?, ^, _, `, {, |, } or ~. One or more periods may be
embedded in an alias, but each one of them should be preceded and followed by at least one of the other characters.
Unicode characters from U+00A1 to U+00FF are also valid in an alias, but they will be mapped to a best-fit US-ASCII
string in the email address which is generated from such an alias.
