How to fix receiving event invitations on my aliases

M A S 0

Hi, I've stopped receiving calendar invitations (.ics meeting invites) sent to my email alias on this Hotmail/Outlook.com account. The emails don't arrive anywhere at all- not in Inbox, not in Junk, not in Deleted Items.

Key details:

This only affects invites sent to my alias address, not necessarily my primary address
Other recipients booking through the same sender/tool receive their invites without issue, so it isn't a sender-side problem
I've already checked and ruled out:
- Blocked senders and domains list (nothing blocking the sender)
- Inbox rules (no rules that could be moving or deleting this mail)
- Mailbox storage (currently at 18% usage, well within limits)
- Junk/Spam folder (invites are not landing there either)

I have been using these aliases for 15 years and never had problems until this year

Just to confirm that we are all talking about the same thing - When you say "alias" you mean an email address that is shown on your Microsoft Account "Manage how you sign in to your account" page at https://account.live.com/names/manage ?

Hi M A S,

To help isolate the issue further, I recommend testing with:

A meeting invitation sent to your primary Outlook.com address
The same invitation sent to the affected alias
A regular email (non-calendar message) sent to the alias

You can also try temporarily setting the affected alias as the primary alias on the account and then retesting. If invitations still do not arrive anywhere in the mailbox, the issue is more likely related to Outlook.com's backend processing of mail sent to that alias.

Please let us know the outcome of the primary-address vs. alias-address test, as that will help narrow down whether this is an alias-specific delivery issue or a calendar-processing issue.

Hi, yes switching the alias as the primary alias has seem to resolve this issue. my question is now will this move the problem of not receiving invitations on the original email?

Hi M A S,

That's good news and it helps confirm that the issue is likely related to how Outlook.com is processing invitations for the alias rather than a problem with the sender.

Changing the primary alias should not automatically cause the same issue to move to the original address. The original email remains an alias on the account and should continue to receive mail normally. However, since the behavior appears to be tied to the alias configuration itself, it's worth testing:

Send a meeting invitation to the new primary alias.

Send another invitation to the original address (now a secondary alias).

If both are received, then the issue may have been resolved simply by refreshing the alias configuration when the primary alias was changed.

If invitations stop arriving on the original address after it becomes a secondary alias, please let us know, as that would suggest the issue affects secondary aliases specifically and may require further investigation by Outlook.com Support.

Please share the results of those tests when you have a chance.
