I already have a ticket open with support, but I wanted to know if anyone else has seen this error when archiving a PST file:

Archiving message failed.  Error code: -2046546390, MsgId: 42F534826D356B7570015B0894651EA65E4AEE0774E6166200, Folder: \Sent Items 2004\, Subject: RE: INVOICES Date: 2004-12-13T22:06:58. Error Decription: (0x86042E2A) [ExJBContainerArchive.exe, CExArchiveThread.cpp(245).CExArchiveThread::Run]

Tried it a couple of times and get the same error.
