  2. Receiving IIT Bombay email to Gmail: This can be achieved in two ways. a) Using IIT Bombay Mail Forwarding, b) Using POP3 protocol to fetch emails in IIT Bombay inbox by Gmail

    1. IIT Bombay email forwarding: By doing so IIT Bombay server will forward all incoming email to your desired email ID, it may be Gmail or anything else. This is the easiest method for getting incoming email but if you opt for this IIT Bombay will not keep any copy of your email in institutional mailbox. Following is the procedure

      1. Open and click “Log into LDAP System”. Enter your Institutional ID and password and login.

      2. Click “Setup AutoForward or AutoReply” under “Change Details” Section.

      3. Select “Forward” and enter your Destination email ID in “ForwardingAddress” field, click “Submit”Gmail Sync IITB 8 

      4. All incoming email will be forwarded to your destination email now. This may takes 10 – 20 minutes to active.

      5. If in future you want to Remove this forwarding follow the same procedure till “Step ii” Select “NoForward” in “Step iii” and Submit. Remember One of the three option i.e. “Forward”, “NoForward” and “AutoReply” works simultaneously.

      6. NOTE:

        • This will forward email from Current time. If you want to get old emails from your IIT Bombay Inbox to Gmail use the POP method described bellow.

        • NO Local Copy of Incoming email will be in IIT Bombay inbox.

        • You must opt for this option if you want to get incoming email to your institutional ID after passing out of the institute. Else after passing out your institutional ID will be fully removed.

    2.  Using POP to Fetch all emails in Institutional Inbox by Gmail: In this process all your old emails in Inbox and subsequent new emails in institutional ID will be copied to gmail. Your emails in IIT Bombay inbox will not be deleted but they will only be marked as read once fetched by Gmail. Only cone is this method is not instantaneous as previous one. Gmail fetch emails once per hour. Remember Gmail fetch email from IITB Bombay Inbox Only, Emails in sent mail or any other folder will not copied. Move them into Inbox before applying this.

      1. Go to “Accounts and Import” in Gmail as described in “Step 1.i” and “Step 1.ii” of this article. Scroll down a little select “Add an email account” under “Check email from other accounts” section as follows.Gmail Sync IITB 9 

      2. Enter your Institutional ID and click next as followsGmail Sync IITB 10 

      3. Select “Import emails from my other account (POP3)” and click Next

      4. You’ll get the following. Be careful here.Gmail Sync IITB 11 Use your institutional Email ID and password. Now

        • IIT Bombay POP server doesn’t work with Gmail (For past One and half year till today, Don’t know why..!!). You’ve to use IIT Bombay IMAP server “” and port 995. Usually this is the default configuration Gmail nowadays providing for IIT Bombay POP. If that’s not with you, please click on drop down select “Other” and enter the above IMAP server details and Port.

        • Must check “Leave a copy of retrieved message on the server” option. Else retrived emails will be deleted from IIT Bombay account

        • Check to use SSL always.

        • Now last two options is up to you. If you Label Incoming messages your messages from IIT Bombay inbox will go in a separate Label (Gmail use Label instead Folder, which looks like folder) along with inbox. Now if you want to keep your inbox clean from thousands of old message Check the last option “Archive incoming messages (Skip the Inbox)”. This will keep fetched emails in selected label only and skip Inbox.

        • Now you may want new emails to be in Inbox after fetching of old emails is over. This is a little tricky. Gmail fetch maximum of ~200 email per hour. It will take time depending on number of email you have in IIT Bombay inbox. Keep checking number of emails in that Label after 1 or 2 hour interval. When fetching of old email will be over number of emails in that folder will no more increase. Now repeat steps from 2.b.i and Uncheck”  the option “Archive incoming messages (Skip the Inbox)” and finish it. Now new emails will start to appear in your Gmail Inbox only. Please keep patience, Gmail sometime takes a little time to start fetching emails.
