With the outbreak of the Greco-Turkish War in February 1897, Aziziye was mobilized into the 1st Squadron.
On 19 March, Aziziye and the ironclads Mesudiye, Hamidiye, and Necm-i Şevket and three torpedo boats departed the Golden Horn, bound for the Dardanelles.
The squadron stopped off Lapseki on 22 March, having lost two of the torpedo boats to unseaworthiness.
The Ottomans inspected the fleet and found that almost all of the vessels, including Aziziye, to be completely unfit for combat against the Greek Navy, which possessed the three modern Hydra-class ironclads.
Despite the fact that Aziziye and her sisters had been refit just three years previously, the inspectors discovered that many of the pistons on their Krupp guns were bent, rendering the guns useless.
Worse, the breeches for Aziziye's 240 mm guns were left at the Imperial Arsenal.

Through April and May, the Ottoman fleet made several sorties into the Aegean Sea in an attempt to raise morale among the ships' crews, though the Ottomans had no intention of attacking Greek forces.
During this period, she, Necm-i Şevket, and the river monitor Hizber escorted troop transports from western Anatolia to Gelibolu, though their presence was simply for show.
While on this duty, the ships conducted gunnery training outside the Bosporus.
On 15 May, Aziziye and the ironclads Mesudiye, Necm-i Şevket, Osmaniye, and Hamidiye, along with several other vessels conducted a major training exercise, where severe deficiencies in the level of training were revealed, particularly with the men's ability to operate the ships' guns.

The condition of the Ottoman fleet could not be concealed from foreign observers, particularly the British Admiral Henry Wood and the German Admiral Eugen Kalau vom Hofe, who led the inspection.
The fleet proved to be an embarrassment for the government and finally forced Sultan Abdul Hamid II to authorize a modernization program, which recommended that the ironclads be modernized in foreign shipyards.
German firms, including Krupp, Schichau-Werke, and AG Vulcan, were to rebuild the ships, but after having surveyed the ships, withdrew from the project in December 1897 owing to the impracticality of modernizing the ships and the inability of the Ottoman government to pay for the work due to its weak finances.
Following a lengthy process of negotiations, Krupp received the contract to rebuild Aziziye on 11 August 1900, along with several other warships.
By December 1902, however, Krupp withdrew from the deal, and Aziziye was ultimately not reconstructed.
She became a barracks ship in 1904, based in Kasımpaşa.
On 31 July 1909, she was decommissioned, but remained in the Navy's inventory until 1923 when she was broken up.
