Reply All does not work showing "The operation failed" error

Using Microsoft Outlook version 2201 (Preview Channel) I get the same error on two different computers when I use Reply All:

The operation failed. The messaging interfaces have returned an unknown error. If the problem persists, restart Oulook.

I already tried to restart outlook, change profile, create another profile, but the error continues.

Creating a new profile I also created a new .OST file, so I would exclude that the issue is a corrupt file.

The error does not show when I am connected to a personal Hotmail account. The error only shows up on my work account.

Because it happens now on two different computers (desktop and notebook) it does not seem something corrupted at the PC level.

Additional note: also ReplyAll from VBA (using Outlook.MailItem) failed, in that case without showing the dialog box UI.

The Reply and Forward buttons and corresponding VBA commands work regularly.

I also monitored with Process Explorer to see whether there are errors accessing Registry or File System, but I didn't see any particular error when I click "Reply All".

In the Event Viewer I have this entry in the Microsoft Office Alerts:

Microsoft Outlook

The operation failed.  The messaging interfaces have returned an unknown error. If the problem persists, restart Outlook.

P1: 301670

P2: 16.0.14827.20186

P3: 

P4: 0x80004005

My only suspect at this point is that there is something that happens with version 2201, but I don't know how to get more details about the error to investigate deeper. Any help would be welcome.

    Gabriel,

    It appears that creating a new Outlook profile doesn't always eliminate the problem. I have a number of accounts and a number of Outlook rules on several, so creating a new profile is a tedious process.

    Further, elsewhere there are reports that claim this error occurs when a Google Apps Sync for Outlook and an Exchange Server account are configured in the same profile. See: https://docs.microsoft.com/en-us/outlook/troubleshoot/profiles-and-accounts/operation-failed-send-email-outlook

    It turns out that I don't use Google Apps Sync for Outlook, so that isn't my problem. But since you didn't know that, I am even more skeptical that you have a full grasp of the problem. I am not trying to be rude here, but while I will be pleased to help Microsoft isolate the cause of it reporting an "unknown error" that is at best a mis-feature. I am reluctant to go through something that is, at best, going to make the error disappear in this one instance, but not get to the fundamental cause.

    cedricc,

    Where are you seeing the Global Address Book? If that is in the Portal, is it EAC or some other section? What I am seeing for Aliases is to go to the portal https://admin.microsoft.com/ then to Users, Active Users, and then click on the account and see the Aliases there (see image below). Does that show the same you are seeing in the Global Address Book?

    I checked with the team about PR_PROFILE_USER_MANAGED_ALIASES_W. It is stored in the registry of the profile encoded so we cannot see it with Regedit. There is an internal tool called PeekProfile and it is supposed to show it but I never found the aliases using that tool. The bug for the Reply All Operation Failed says that the max aliases Outlook could handle was 30. If you still repro and can remove some aliases down lower than 30 and test please do and see if that helps. The Outlook Team was supposed to remove this part of the feature until the alias issue could be fixed so we should not be seeing the issue as far as I know. I still want to make sure we are accounting for the aliases wherever they are stored though.

    Strangely enough, I don't have a PR_PROFILE_USER_MANAGED_ALIASES_W key in my registry...

    Hi

    Creating a new profile do not always solves the issue. Didn't for me.

    But it's true that I have a big number of aliases. What was said in previous messages is not completely correct. The number of aliases is not what we see clicking on the from field, aliases are defined on the admin portal as a user setting.

    They can be checked going in the Global Address Book, / affected used / "Email addresses" tab. I have 44 there, which might be the issue.

    Cheers
