To fix Hotmail Connector error 1133 you need to close Outlook and delete or rename the Hotmail data file. Open Outlook and let it resync.
In Windows 7/8, you can paste %localappdata%\microsoft\outlook in the address bar of Windows Explorer and press Enter to open the folder where the ost is. In Windows XP, use %USERPROFILE%\Application Data\Microsoft\Outlook.
We're seeing error reports from some users with an Outlook Hotmail Connector in their profile who've set the Connector's message store to be their default delivery location, only to receive error 4102. It's a not widespread error and I'm unable to reproduce it. If you receive this error, try setting a pst as the default message store.
Other receive this error when they have the junk email settings out of sync. both Hotmail and Outlook need to use either High or Low. you cannot use Low in Hotmail and High in Outlook.
Also see Hotmail Error 4102 (Outlook Tips) for a possible cause when the Hotmail account is set as default.
If you're receiving error 4202, one or more addresses in the blocked and safe lists contain an underscore or is malformed. This error shouldn't prevent a person from sending or receiving messages, as synchronization of mail, calendar, contacts and other data (including the junk lists) continues. Delete the suspect addresses from the Safe and Blocked Senders lists in Outlook and in Hotmail.
If you are unable to delete the entries (often just single words, not domains), you may need to ask the Hotmail system admin to delete the entries. Go to the Hotmail, Messenger & SkyDrive forum at Microsoft Answers and enter "0x80004005" in the search box you will see many similar entries. If you post a question with your details a sysadmin will fix the problem.
Error: 5102. Server. Maximum request length exceeded
We’re seeing a rash of “Error: 5102. Server. Maximum request length exceeded” errors when using the Outlook Hotmail Connector. This specific error is caused by trying to send a file larger than 4MB using the connector. The problem behind the error should be fixed soon, but until then, if you get the error, move the message from your Outbox to a folder in a local pst - the file needs to be moved from the mailbox so Outlook doesn't attempt to sync it with the server. This should get rid of the error and allow the Outlook Connector to work again.
If you need to send larger attachments, use the web interface.
If a sending a large message is not the cause, look in the Sync Issues folder (use Ctrl+6 to switch to the folder list) and check the Synchronization Log messages for text indicating which messages are the problem. You can also check the Local Failures folder and other folders in your mailbox for large messages. Move the messages out of the Outlook Connector account.
