Work account can no longer connect to the exchange after yesterday update.

Question

Work account can no longer connect to the exchange after yesterday update.

Z 0

Hi,

I'm using Outlook classic for my work accounts. There was an update yesterday, and since then my work accounts stop connecting to the exchange. Personal accounts still work. I've done everything including removing the account. Now I cannot add it back. it can never find my account. I signed it to microsoft business admin, nothing changed.

The funny thing is new outlook works. Is microsoft trying to block the usage of outlook classic on work accounts? Or this is typical microsoft rolling out untested updates?

This happen to me also about a month ago, spent 3 hours (5am-8am) trying to fix, then had Microsoft and GoDaddy in helping (for another 3.5hours till 11.30am. Detriment to my work. Raised a complaint haven’t heard from anyone. Having the Microsoft via another provider is terrible when thing go wrong. What is your set up.

in the end the GoDaddy office couldn’t fix it up it’s all registered and logged but then I think I found the hack with a little trick which was to remove my sign in for Microsoft through the Authenticator area. Remove it everywhere them and take away Authenticator and just only use have my mobile number is as a secondary to FA from there. I was able to get it I think.

Good day Z,

Just to gently clarify before going any further, this forum is separate from Microsoft Support. Forum users, moderators and Microsoft external staff cannot access user accounts or directly escalate cases.

Currently, I checked the information currently available and didn't find any reported service incident related to this issue, nor any announcement that Microsoft has blocked work accounts from using Classic Outlook.

Since the issue only affects Classic Outlook, please try the following:

Step 1: Repair Microsoft 365 apps

Close all Office applications.

Open Control Panel > Programs > Programs and Features.

Select your Microsoft 365 installation and choose Change.

Run Online Repair.

Restart Windows, then try adding the account again.

Step 2: Create a new Outlook profile

Close Outlook.

Open Control Panel > Search and open Mail > Show Profiles.

Select Add and create a new profile.

Sign in with your work account.

Set the new profile as the default profile > Apply > OK and open Outlook.

Step 3: Contact Microsoft Support

Since you can access the Microsoft 365 admin center, if your account has the required administrative permissions, you can create a support request directly with Microsoft through the Microsoft 365 admin center > Support > Help & Support for further investigation.

Note: If you don't see the support option or don't have sufficient administrative permissions, please contact your Global Administrator for assistance. In case you do not know who is your Global admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support

A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.

As a forum user, I can provide troubleshooting guidance based on public documentation, and I don't have access to backend tools. For this reason, contacting Microsoft Support is the best next step if the issue continues after completing the steps above.

If you have any questions or need further support, please don’t hesitate to reach out at any time.

Thank you for your patience and understanding.
