Job failed: PST migration of \\MyServer\MyPsts\Sent items.pst: Error 0x80040401
The location and collection tasks work ok but the migration task fails for all migrations with the 0x80040401 error. I've tried googling this but nothing of any substance comes back really.
like you have said most likely a faulty or slow MAPI connection.
one hint regarding pst migrations:
if you connect your pst to your outlook it says what kind of error you are facing with the pst file.
Enterprise Vault is not very generous regarding failed pst migration reports, as it says "undefined error" alot of times.
these are the most common once:
old pst format
