Chief Minister Akhilesh Yadav hosted a lunch in honour of Mukherjee at his official residence.
The former Finance Minister, who is here as part of his election campaign, also met over tea MLAs of Congress, RLD and other allies.
UP accounts for around 1.62 lakh votes of the total electoral college of 10.98 lakh votes.
The Presidential elections in which Mukherjee's rival will be Opposition-backed candidate and former Lok Sabha Speaker P A Sangma are slated to be held on July 19. The Congress stalwart is widely expected to win the contest.

While SP and Congress members along with MLAs of other parties attended the lunch, BSP and BJP members skipped the event.
