Mailbox Retrieval Failed Error: “”

Just to make sure this isn't a fixed issue, try the latest test release: Hold down ⌥ when clicking “Check Now” in the Software Update preferences pane.

(Your settings look fine.)

Hi Benny,

Still same error with the newer test version

The version is r5522.

Is this because I am use .edu email?
Gmail account is working well.

I don't think .edu plays any role, but we'll try to debug and see what we find.

Does it work if you add the account without using “Edit Subscriptions...”?

Do you get the same error? If yes, then try the following:

• Open the Activity Viewer (⌥⌘0). This enables logging.
• Relaunch MailMate.
• Wait for the outlook account to fail (you might need to try to explicitly take it online).
• Use “Help ▸ Send Server Logs”.

Thanks in advance.
