Laid down in 1917 at the Joh. C. Tecklenborg shipyard in Geestemünde, M 107 was launched on 3 July 1918 and commissioned on 30 July of the same year. After active service in 1918, the ship was retained by the Reichsmarine, which was renamed Kriegsmarine in 1935. On 15 April 1939, M 107 was re-classified as a Räumbootbegleitschiff for the newly established 3. Räumbootflottille and renamed Von der Groeben.
In 1940, Von der Groeben was transferred to the 4. Räumbootflottille and participated in the Operation Weserübung, the occupation of Denmark and Norway, as part of Kriegsschiffgruppe 11. On 9 April 1940, Von der Groeben with the rest of 4. Räumbootflottille occupied Thyborøn on the coast of Jutland during the German invasion of Denmark.
Later that year, Von der Groeben served as escort on the Belgian coast until she hit a mine off Dunkirk on 18 August 1940. The seriously damaged ship was beached and later salvaged. After repairs were completed, she was re-commissioned as M 507 on 1 October 1940.
M 507 was deployed to the English Channel coast until spring 1943, and took part of several action against British coastal forces, among them the action of 17-18 August 1942 off Gravelines, when Von der Groeben, along with five other minesweepers, escorted the Italian blockade runner Fidelitas through the English Channel; two British MTBs were sunk.
