I have Office for Mac 2011.

I have two Gmail folders. Don't no why?

I have deleted all files in the Gmail file which has these folders:

(Gmail)

       All Mail

       All Mail

       Drafts

       Important

       Sent Mail

       Trash

I have deletes every email in all of these folders and it rebuilds automatically.  

I get an error message from google that slows up my email that says i have sent too large of file, error code: 1206.

I was hoping that deleting all it would solve problem, but it rebuilds and the problem continues.

My other Inbox looks like this and works fine:

Inbox

    On My Computer

    Gmail

Drafts

Sent Items

Deleted Items
