I set up my office mail with gmail account for work. But one day my gmail stop fetching email from my office mail. The Gmail showing error Server Returned Error “Line Length Exceeded Limit: Line too Long”

 

According to https://productforums.google.com/forum/#!topic/gmail/nJ7tJD9GuFU, there are big size of email that will be fetched. In my case there is one email with size of 30mb.

The solution to this is simply move the big size email on source domain into folder, in my case i use default ms outlook owa to move the email into one of the folder i create.

Then in our setup gmail account (target email) go to Settings > Accounts & Import > Check Mail Now.

Voila! error message gone and your emails fetched seamlessly.
