A client of mine is receiving this error when emailing using Outlook 2003:
#32050 was generated by by MAPISession. Logon failure: valid session ID already exists.
He closes Outlook and reopens it again and continues along his merry way. Then, BAM! 20 minutes later he gets the same error. I checked to see if Outlook was his default email program, and it is. Any PC gurus know what the heck this error means and how to fix it? Buy you a case of beer.
BTW, his OS is Windows XP SP3
