Hi Catherine,

In this case, it's best to figure out whether this is happening at the mailbox/server level or just in the Mac Outlook client itself:

Do the same invites show up properly in your Inbox when you check Outlook on the web?
When the meeting shows up on your Calendar, what's its status?
Is your account a work/school Microsoft 365 (onmicrosoft.com, yourcompany.org or Exchange account, or a personal account (IMAP, Gmail, iCloud, Hotmail, outlook.com) added into Outlook for Mac?
Does this happen with every meeting invite from every sender, or only some (e.g., only recurring meetings, only invites from one particular person, or only invites where you're not the organizer)?
When you search your mailbox for one of these invites (by sender name or meeting subject), does the email turn up anywhere? Deleted Items, Junk, or the "Other" tab if Focused Inbox is on or is it completely absent from Mail?

Once I have a clearer understanding of your current situation, I’ll be happy to assist you with greater accuracy. Please feel free to share any additional details you believe are relevant. Screenshots are especially helpful and much appreciated.

Thank you for your patience and your understanding. If you have any additional questions, please feel free to reach out.

I'm looking forward to your reply.

Hi Catherine,

Since the same behavior shows up in Outlook on the web (not just the Mac app), and the messages don't turn up anywhere in a mailbox search (Inbox, Deleted Items, or Junk), this points to something happening at the mailbox or mail-flow level rather than an issue with Outlook itself.

You will need assistance from your IT administrator to troubleshoot this issue.

Run a message trace on one recent invite (sender + this mailbox as recipient, around the time it was sent) to see whether it was delivered, dropped by a rule, quarantined, or redirected.

Check Mail flow > Rules for anything matching meeting-related message classes that might be deleting or redirecting them.

Check for any rule under Mail > Rules in Outlook on the web that could be silently deleting meeting requests, and any connected add-ins or scheduling tools that auto-process calendar items.

If none of the above shows anything, it's worth checking whether a third-party email security gateway sits in front of Exchange, or whether a Litigation Hold/retention policy is routing these items somewhere other than the visible mailbox.

For a precise live support, your IT admin can use their admin credentials to submit a support request through the Microsoft 365 Admin Center on your behalf.

Microsoft also provides customer service phone numbers based on your region. Your IT admin can find the appropriate contact number here: Customer service phone numbers - Microsoft Support This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.

As community moderators, we’re here to guide you, but due to privacy and security limitations, we don’t have access to the backend tools required for a full resolution. For this reason, contacting Microsoft Support via the Admin Center is the most secure and efficient way forward.
