XADM: Spaces not Allowed in Some X400 Entry Fields

• Microsoft Exchange Server, version 4.0

SUMMARY

When creating a custom X.400 recipient, the following fields on the advanced property page of the X.400 addressing page allow only for numerals 0 - 9. No alphanumeric characters or spaces are allowed. The fields that are thus limited are as follows:

   User Agent numeric ID (n-id)
   X.121 (x.121)
   Terminal Type (t-ty)

MORE INFORMATION

The X.400 specification allows for spaces in the above types, however the Microsoft Exchange addressing scheme (address.dll) does not support spaces in those three fields.

This can become a problem when creating custom recipients to X.400 system recipients who follow this addressing scheme; it could result in a non- delivery report (NDR) to such a user.

WORKAOUND

Currently with Exchange 4.0 the only workaround is to remove the space from the desired user on the above fields so that they match the Exchange format.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
