The error was still flashing up on the screen.

I tried to add it to my another Apple Mail account. I attempted various solutions, but not even a single method worked for me. For the same purpose, I searched on the internet. A few days ago, I want to access my Office 365 data into my Apple Mail account. “I use Office 365 for my business purpose and Apple Mail for personal use. Please, can you help me to find an appropriate solution? I would be highly thankful.” Some of them were manual and others were automated. Now, I searched for it and came across my solutions.

For this, I would like to add Office 365 to Apple Mail. But, I was thinking to take backup of my Office 365 data. No doubt, it is an excellent platform for sending and receiving emails. We have been working with Microsoft Office 365 for 2 years.
