Links to shared Outlook.com calendars return status code 500

This is a problem on Microsoft's side that the Outlook.com team need to fix. This issue is probably affecting many users. Until Microsoft realises it, and that more users start screaming, there is nothing we can do. Level 1 techs like Griridhar J won't do anything for us and do not understand that an error 500 is a SERVER SIDE ISSUE and has nothing to do with our computers or browsers...

I'm switching to gmail, I don't have time to wait after them.

I can't fix this same problem that I have with a shared calendar. It has been working great for ages but failed last week. I can still access the calendar by logging in but can't use the links. I have tried resetting permissions and recreating links but still not working. I need the solution quickly as this calendar is used for notifying people when they are on a shift at a community radio station.

I have this problem on all computers I have tried with Windows7 and 8.1.

I have tried the solutions mentioned about with no change.

Thank you for your answer but this is not a client problem or a problem with the browser. I tried on multiple browsers, computers and on different networks, and still the same. An HTTP Error 500 indicates an internal server error and has nothing to do with the client comptuer. 

I contacted a Microsoft support tech yesterday and my issue was escalated to a tier-3 support representative. The issue was indeed a Microsoft problem and was fixed. However the issue STARTED AGAIN TODAY...

Please see support request ID 1294645297.

I'm going to reopen the case, but if the issue persists I'm going to have to switch to gmail...

Thank you.

Tried all Three browsers,  and cleared all the Cookies problem still persists.

Which browser are you using?

Follow the steps below and check if it helps.

Try to logout and login and check if issue persists.

Step 2

One of the possible reasons why you are encountering this problem is that there are corrupted cache/cookies/browsing history stored in your browser. I recommend that you clear your browser's cache/cookies/browsing history.

Let’s try to clear them using the following steps:

• For Internet Explorer: Press CTRL+SHIFT+DEL simultaneously and click Delete.
• For Google Chrome: Press CTRL+SHIFT+DEL simultaneously and click Clear Browsing Data.
• For Firefox: Press CTRL+SHIFT+DEL simultaneously and click Clear Now.(other browsers are similar)

Step 3

Try to open in InPrivate mode and check if issue persists. Follow the steps below:

1. Press Windows key + R.
2. Type ‘iexplore.exe –private’.
3. Check if issue persists.

Step 4

If issue still persists try using a different browser and check if it fixes the issue.
