I already have read the old posts for backing up M365 using synology and all. But my organization is very small. I just have 7 users in M365 so can someone suggest me an open source solution or Free solution which I can use to backup my mail box data locally.
Also altogether I want to ask one more question. I am working part time for my school and my contract will end soon. So they have emailed me to take all my belongings from my M365 account.
I was also looking a way where I can take backup of that account.
