Good day! If this is your problem and your password is working - be informed that the DepEd Central Office has aggressively transition now on the use of DepEd Email Service. This means that only a few to no emails will be received thru GMAIL. To continue receiving and checking your respective emails, you need to use your Microsoft DepEd Email Account and login thru https://office.com  and select the "Outlook" icon in the selection of applications from Microsoft (the blue document icon with the letter O).
