Hi, I have three outlook.com email accounts configured. Two accounts open to show all subscribed folders. One account shows the account name only, but no folders. Activity manager shows: "The current operation on 'Outbox' did not succeed. The mail server for account wasaga72@outlook.com responded: Command Error. 12" Sometimes all folders show. Sometimes all folders show after a delay. Tried: 1 deleting all .msf files. 2 removing and re-adding the account My wife and I both have identical Laptops with the same three outlook.com accounts. Mine using version 148.0.1 (64-bit), hers using 140.8.0 esr (64-bit) both have the same problem. Any help would be appreciated, John
