I contacted Samsung support about this and again they said the issue has not been reported.
This are the solutions they gave to me, it did not work for me, maybe it will for you
Dear Ernesto Melendez,
Thank you for contacting Samsung Telecommunications America.
After reviewing your E-Mail, we understand that you are experiencing issues while syncing E-Mails on your Samsung Galaxy Note 3 device(SM-N900T).
We are sorry to inform you that as of now there are no reported issues with the device. However, please perform few troubleshooting steps and check with the result.
Make sure that you are using the default E-Mail application that came along with your phone. Please confirm if the issue is with all the E-Mail accounts configured on your phone or with any particular E-Mail account. Remove and re configure that E-Mail account and check with the result. Follow the steps below to remove E-Mail account from your phone.
From Home Screen, tap on Menu >> Settings >> General >> Accounts >> Tap on E-Mail >> Tap on the listed E-Mail accounts >> Remove Account.
After removing the E-Mail Account, please re configure it from the default E-Mail application and check with the result.
If the issue persists, please perform a Soft reset on the device which will refresh the internal circuitry of the device and the data on the device will not be erased.
1. Turn off the handset.
2. Remove the battery and wait for 30 seconds.
3. Reinsert the battery and turn ON the device.
If the issue persists even after a Soft reset, we request you to Clear the cache partition of the device. By performing these steps the data on the phone will not be erased, only the temporary files, bugs will be removed. We will provide you with the steps.
1. Power the device off (remove and re-insert the battery).
2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
3. When the device vibrates; release only the Power key.
4. When the Android system recovery menu displays; release the Volume Up and the Home key.
5. Navigate with the Volume keys to the wipe cache partition option and press the Power key to select.
6. After the process completes, press the Power key to reboot system now.
