I was using Microsoft exchange email on apple mail , but After updating to Tahoe 26.2, my email automatically went offline and was not responding. I deleted the account and tired to re add it. but I am receiving this following error every time. "The operation couldn’t be completed. (com.apple.accounts error 3.)"
However, it is working fine on my iPhone.
please help me how to resolve this issue.
MacBook Pro 13″, macOS 26.2
Re: "error Msg popping while add mail account on APPLE mail."
You might want to try logging into that Microsoft email account from its website.
Sometimes the Settings change or update when improvements or changes are made to the account or the website.
Please check that Apple Mail is authorized for (ie: allowed access to) the account in the email account's settings.
You're not alone. We've been experiencing the same issue across our institution. All Apple Mail customers have lost their ability to access M365 from macOS, but it is working fine on iPads and iPhones for now. The error message is always the same.
Unfortunately, we don't have a workaround or a fix yet.
Thank you kindly for joining this discussion, and for sharing your experience with the community.
