when you say the list for the user is setup 51, which the default for each file is 25 MB, the total attachment might be setup 51 so try attaching 2 files of 25 MB each if it goes that means the limit is set correctly for the whole attachment.

Here are the docs https://docs.microsoft.com/en-us/exchange/troubleshoot/mailflow/cannot-add-attachment-outlook-web
