Install Office 365 get error code: 30183-48(401)

Hi All,

We apologize for the inconvenience caused by this issue.

Considering that different uses from different tenants are experiencing the same Office issue with same error code, I'm afraid it could be a temporarily server-side issue which needs to be investigated and fixed from back end.

I sincerely recommend you raise a support ticket from Microsoft 365 Admin Center to report this issue. The support team over there has higher permission and more resource to investigate issue from back end. The more reports they receive from different customers, the more likely they will be able to find something affecting users in common and fix it soon.

Note: To create a support ticket, you need to have Microsoft 365 admin privileges and if you aren’t admin of your Microsoft 365 organization, please contact the admin of creating a new ticket.

Apologies for redirecting you to the related team support as the moderators in this community have limited resources to check the backend information, and to get the fast and better assistance we requested for it.

Appreciate your patience and understanding and thank you for your time and cooperation.

I discovered that the apps (Outlook, Word, etc) did install and seem to work fine despite the installer crashing.

There is a host of people having this (or very similar) problem since the last update. It's clearly a sever-side issue on Microsoft's end. Posting a canned response like this is not helpful.

What I have found after having thrashed with it for more than a day is that the applications seem to have been installed correctly despite these Setup.exe errors and no longer throw the "We're sorry..." error but it remains to be seen if Outlook etal. are stable.

Look in the history of my replies. As I said, it APPEARS that it's just the setup program that's failing in its final steps. The Office 365 apps seem to be working. Go ahead and try running the the apps despite the setup error message.

Same issue. Error code 30183-48 (401)

Office 365 A1 Plus for faculty, if this is significant. A group license.

It was previously installed on my machine. A brand new machine. Windows 11. Had some problems with Outlook (couldn't set up a Gmail account). Tried uninstalling and reinstalling. Now I can't install at all. Paused antivirus and firewall. Same issues. It gets to 95% and then gives the error message.

Thanks for helping.
