Question

365 removed and will not allow me to add my outlook email back to my account.

Austin 0

I heave a paid subscription for 365 Family. My 365 login email for the account is an i-cloud email. I used to be able to login to 365 and access my outlook email via the outlook app link. I no longer can which keeps me from auto adding calendar events that are emailed to me. I tried and it will not let me add the outlook email to my account saying it is already used. I have had this account since 2022, what changed? How can I add my outllok.com email back to my account? How does it get removed so I know if I should avoid anything in the future?

Hi, @Austin

Microsoft does not allow an existing @outlook.com address that belongs to another Microsoft account to be added as an alias to your iCloud-based Microsoft account. Microsoft accounts also cannot be merged.

Microsoft currently requires accounts that use only a third-party sign-in address, such as iCloud, to have a Microsoft Outlook/Hotmail alias before Outlook.com mail and calendar can be used: https://support.microsoft.com/en-us/support/known-issues/fixes-or-workarounds-for-recent-issues-on-outlook-com

To help narrow down what happened:

If you go directly to https://outlook.live.com and sign in using the @outlook.com address and its own password, can you still access the original mailbox and calendar?
When you sign in at https://account.microsoft.com/services using the iCloud address, is your Microsoft 365 Family subscription still listed there?

Yes my 365 account is there. My outlook email was created through/when I originally set up the account (logged in with the iCloud email). They were not separate until now. I used to have 4 outlook emails associated with the iCloud account login. My wife and kids couldn’t stand outlook so I removed theres. Mine was and has been still there. I am with many others that Classic Outlook was MUCH better than new outlook in most ways. If 365 did not separate the accounts, who did? Only 365 could have with an update. So if Microsoft cannot fix it now, please let me know when they can. Otherwise I’m going to have to quit outlook as well.

Thanks for clarifying.

Since that Outlook address was originally created under the same Microsoft account, please sign in with your iCloud email here:

https://account.live.com/names/manage

Does your @outlook.com address still appear under "Account aliases"?

That will tell whether the Outlook address is still attached to the same Microsoft account or whether something changed at the account level.

Thanks!
