How to delete all communication records

I stopped my email account incoming mails and unchecked the create contact from incoming mail. now i want to delete all mails which stored in my lead and communication doctypes.So i selected all and clicked delete button in action option. but still it is not deleted.

Hi @Sumith-2004:

Any errors on browser console? Any element is deleted?

actually my bulk delete has limits i think so. so only i cant delete everything . but after asked to chat gpt. and i deleted it as 10 by 10 records.
but i want to know how to increase the limits for bulk delete. can guide me for this

Hi @Sumith-2004 :

Maybe a performance/refresh issue … Bulk deleting is a background job, so maybe you will need some time until get documents deleted.

oh okay thank you
