He performed poorly with the bat, but obtained the best test bowling figures in a match by a Bangladeshi on debut, with an eight-wicket haul, including a five wicket haul in the second innings.^[44] This played a major role in Bangladesh's second Test win, and the first on foreign soil.

As permanent member

Although Mahmudullah scored a Test century batting at number 8 against New Zealand, the selection committee preferred not to promote him up the order due to a perceived weakness against fast bowling, despite the number four spot having no permanent occupant.^[45] He was included in Bangladesh's 15-man squad for the 2011 ICC Cricket World Cup.^[46] On 20 September 2011, Mahmudullah was named Bangladesh's vice-captain, taking over from Tamim Iqbal after the previous captain and deputy were sacked.^[47] When West Indies toured in October, Mahmudullah missed all the fixtures with a viral fever.^[48] He recovered in time to rejoin the squad to face Pakistan in three ODIs in November.^[49] Mahmudullah scored 56 runs and bowled in just one match, taking three wickets from seven deliveries.^[50][51]

With that Mahmudullah was named as captain of the Test team.^[58] On 31 January 2018, he became the tenth player to lead Bangladesh in Tests.^[59][60] Shakib Al Hasan was also ruled out of the first T20I, with Mahmudullah once again named as captain in his place.^[61] Under his captaincy, Bangladesh recorded their highest total in T20Is (193/5), but finally lost the match for Sri Lanka in Tri-nation Series in Bangladesh.^[62] In the next match against Sri Lanka in Nidahas Trophy, Bangladesh scored 200 runs for the first time when they chased down 214 to win the game.^[63] On 16 March, Mahmudullah scored an unbeaten 43 runs and made Bangladesh qualified for the Nidahas trophy final by hitting a six in the last decisive over to reach the target 160 runs for victory against Sri Lanka in the semi-final match.^[64]

In April 2018, he was one of ten cricketers to be awarded a central contract by the Bangladesh Cricket Board (BCB) ahead of the 2018 season.^[65] He was named captain in the squad for the home series against West Indies but Shakib al Hasan returned and captained.

In July 2021, he was added to Bangladesh's test squad for the one-off Test against Zimbabwe, after a gap of 17 months. The match was his 50th test match and he scored an unbeaten 150 runs, his career best in the first innings and making a 191-run partnership with Taskin Ahmed for ninth wicket, highest for Bangladesh, helping Bangladesh to win the test match by 220 runs. Eventually, he announced his retirement from test cricket after this match as well.^[69][70][71] On 20 July 2021, during the tour of Zimbabwe, Mahmudullah played in his 200th ODI match.^[72] In September 2021, Mahmudullah was named as the captain of Bangladesh's squad for the 2021 ICC Men's T20 World Cup.^[73]
