Outlook 2011 for Mac has begun asking me for my Gmail password everytime I open up the application (account information window always popping up and I cannot send/receive without re-entering my password). It also frequently asks me for the password when the application has been open for a while. It did not do this before. Why has this started to happen and how do I fix it please?
Hello. I tried to set up my ipage email and was able to receive email but not send email through outlook. I used all of the settings they suggested to no avail. Anyone have any experience with errors like this? 

Cannot send mail. The SMTP server does not recognize any of the authentication methods supported by Outlook. Try changing the SMTP authentication options in Account settings or contact your network administrator.

Account name: "N8productions"

error code -17092



Thanks
I am not having problems receiving but cannot the majority of my emails stay in my outbox from my Yahoo mail account.  I receive an error message: connection to server failed or dropped.  This only happens with Yahoo mail and at times it will go thru.  I have Mac 2011.  Please help
When I used Outlook in Windows  6 years ago, I could change the colour of the preview message header so I knew what mail was unread. Is this possible in Outlook for Mac? 
I have outlook running through exchange company and now have office 2011 home edition i want to install but am worried it will over write my outlook with what comes with the office install.   when i first tried this it didn't work because i had some old files left over from a previous time.  When i uninstalled through the advise on this site i got the office to install properly but i noticed it had office which could be bought later.  
But i then installed outlook from my exchanger company but this messed things up, so had to uninstall everything again.  As i need outlook now i re installed from my exchange company so i'm back to normal but now i'm worried it will over write outlook when i install office.

Can any one tell me if this is true or what i can do to get around this?
Outlook for Mac 2011 repeated comes up with error 5.2.3 Data size exceeds maximum permitted Error code 17099. This slows down the sending off emails. Also error 5.5.0 code 17092 for a few specific email addresses that Outlook says it are invalid.  These errors continue to accumulate every 3 minutes or so until deleted from the error message dialogue box.
I have two outgoing messages "stuck" in the outbox system, though not showing in the outbox. How can I delete them? (I have an AppleMac and Outlook 2011.) The messages had scanned attachments and were rejected due to their size. Outlook tries to send them every time I do send/receive, causing delay and major frustration. Can you help please?

When I create a new folder in Outlook for Mac 2011, the new folder is not displayed on my Android tablet (Exchange mail connection).  However, the new folder is displayed in MS Outlook 2010 for Windows.

New folders created in MS Outlook 2010 for Windows are displayed on all of my devices.

How can I create a new folder in Outlook for Mac 2011 that will be also displayed on my Android Mail App?

Thanks
