Jaishankar also thanked everyone for their good wishes.
"Thank you all for the best wishes! Honoured to be given this responsibility. Proud to follow on the footsteps of @SushmaSwarajji," tweeted JAishankar, who took charge on Friday.
Sushma Swaraj was known for constantly solving common man's problems, always available on Twitter. Similarly, following Swaraj's footstep, Jaishankar also started 'troubleshooting' through Twitter.
A Twitter user Rinky wrote to Jaishankar asking for help.
"@DrSJaishankar @smritiirani I need your help. My daughter is 2 years old. I'm struggling from 6 months. Please please help me. Contact me. She is in USA and I'm at India. Please... I'm waiting for your prompt reply," Rinky wrote.
In reply, Jaishankar tagged Harsh V Shringla, ambassador of India to the US, in a tweet and asked Rinky to share her concern with him.
"Our Ambassador @harshvshringla is on the job. Please share with him all the details @IndianEmbassyUS," he wrote.
Jaishankar has previously served as Foreign Secretary from 2015-2018 and was appointed as Minister of External Affairs in the newly formed BJP-led NDA government.
Jaishankar's "always available" tweet came a day after his son Dhruva Jaishankar attracted attention with his reply on a tweet seeking help with a passport or visa.
Dhruva has received a request regarding help with visa or passport. Replying to the tweet, he said: "Dude. Wrong Twitter handle."
"Before anyone asks, I can absolutely not help anyone with their passport, visa, or getting-you-out-of-a-foreign-prison problems," he added.
"I have plenty of those problems myself (other than the prisons - I try to stay clear of those)."
The tweet was later deleted by the twitter user, though the replies by Dhruva stand on the micro blogging site.
