Question

Outlook Calendar won't sync with iphone calendar app

Fran Sachs 20

My iphone calendar app hasn't been syncing properly with my Outlook Calendar on my PC. I followed the iphone recommendation to delete the account and reload. Now I have NO calendar data on my iphone. I called iphone and they said I did everything right so it is a Microsoft issue. But I can't figure out how to fix it. Please help.

Thanks for your response. I appreciate it. I had done all of these things. It seems it just took a REALLY long time to load. I checked it before I went to bed and the calendar had re-loaded, so it seems all is well. I do appreciate your help.

Dear @Fran Sachs,

Thank you for posting your question in the Microsoft Q&A forum.

As a moderator, I don't have the tools to investigate your specific account directly. Because this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. However, I will try my best to guide you as clearly as possible.

First, to ensure the calendar still exists, please check your calendar on the Outlook app for me to see if the data is still there.

If your events are there > data is safe, syncing is the issue. If events are missing here too > this is account issue.

May I ask, I see your tag is 'Exchange', I want to double-check if you are using Exchange (a work/school email) rather than Outlook.com (a personal email); please confirm this for me. If it is Exchange, when you reconnect, you must select 'Exchange,' enter your company email account, enter 'Exchange' in the description field, and then tap 'Sign In.'

These are the steps to add an account for an Exchange account; please kindly help me double-check to see if you re-added it correctly:

You mentioned that you already deleted and re-added the account, right? Since nothing is appearing, could you please take a screenshot of your calendar account section for me? Additionally, tap on Exchange > Account Settings and take a screenshot of that as well so I can see the account details. Please help me send these photos to me via private message, as they contain personal information.

Note: To access your private messages, there will be a notification at the top of your post; please click on 'View Message.

With your help, I will try to pinpoint the exact issue you are facing.

I look forward to your support and response!
