Usernames containing special characters hinder PIM processing
Posted by - NA - on 29 June 2009 11:09 AM
An email account created with a username containing special characters experiences successful mail processing cycles, however, PIM processing cycles fail and display errors.  On the User Statistics page, the check mail cycle is successful, but PIM stats show error 551 (the pim log will show error 401).

This issue involves usernames that contain one or more of the following the characters for Exchange:

  • ampersand (&)
  • plus sign (+)
  • percent sign (%)
  • number sign (#)
  • dollar sign ($)
  • exclamation point (!)
