Daniel C. Taylor, who has extensively explored the Makalu-Barun area and written a book on the mystery of the Yeti, said the footprints were likely those of bears.
However, the Indian army's tweet still prompted a flurry of jokes about the discovery.
It said its "evidence" has been "handed over to subject matter experts".
According to folklore, the yeti, or abominable snowman, is an ape-like creature that is taller than the humans.
The pictures showing 32-inch footprints have gathered more than 12,000 likes on social media - but many were quick to mock the unbelievable find made by the army on April 9.
Many have attempted to locate the creature, including the conqueror of Mount Everest, Sir Edmund Hillary but they all found nothing.
The Yeti tweets have drawn ridicule and confusion from social media users around the world.
Although tales of the Yeti first caught the imagination of the Western world in the 19th century, the hairy ape-like figure, taller than a man, has always been a feature of folklore in Nepal.
"With all due respect, institutions such as yours should be more responsible and careful before going ahead and declaring the sighting of any footprints as "Yeti's"!", said Kushal Prajapati.
"So far, our findings and all genetic evidence extracted from claimed yeti remains have demonstrated that they came from bears that live on the region today", Lindqvist said.
In 2013, a British scientist claimed the yeti may be a sub-species of brown bear. Anup Sah (60), a Padma awardee naturalist and photographer who had been part of over a dozen Himalayan expeditions, told TOI that mostly these are cases of Himalayan Brown Bear, Tibetean Blue Bear footprint or hallucinations at high altitudes.
