Block PST file but Allow .MSG file

Dear All,

I am using latest Nextcloud.

due to space issue, we dont want to keep .PST file but if there is any exported message file from outlook which will be .MSG file should be allowed.

is there any way to achieve this. i see using MIME Type we can block PST under Access control but that is blocking .MSG file also.

looking for some solution.


Dear All,

Anyy help please ?
