Cannot share to do list

Question

Cannot share to do list

SelAromDotNet 76

I created a list and am unable to share it with my wife. We are both logged in with personal (not work) accounts. When I create the shared link and send it to her she gets the error: Can’t join list It looks like this list isn’t available. Try contacting the person who invited you.

when she sends me a list invite link I see the same error message.

We each both get a notification on our PC that the other has joined, but then they are immediately removed and no longer shared.

We have tried deleting the list and trying again. we have tried stopping sharing and resharing. we have tried logging out and in, we have tried incognito browser sessions. we tried uninstalling the app and reinstalling and the result is the same, on desktop, web, and mobile.

I'm positive it's a problem with my Microsoft ACCOUNT and not the app, but support keeps telling me to just "login with my microsoft account" and it will resolve the issue. to do support sent me to outlook support saying it's a problem with my account, outlook support sent me back to to do support saying it's a problem with my account.

so what the F am I supposed to do here? there is clearly an issue with my microsoft account because this isn't the only service that is giving me issues. I can't open shared one note notebooks from my family either.

how am I supposed to get actual support for this problem? I am seriously done with microsoft, and am working to migrate exclusively to google services as I'm so sick of nothing working when all I'm trying to do is use BASIC FEATURES of the platform and getting absolutely NO SUPPORT for a service I'm PAYING FOR.

Exactly the same issue. Business account. Im trying to share a list with 4 others who also have business accounts under our domain. It was working fine for 2 years, now 3 have stopped working for no reason and can no longer connect.

If it wasn't for our clients, I would dump everything Microsoft in a heartbeat.

Hi Jamie Baldwin, Francois, and Nayeli Velazquez,

I’m seeing the same symptom across multiple recent threads. At the moment, the best next step is to submit in‑app feedback (To Do > Settings > Suggest a feature / Feedback) and also open a support request referencing that the join is briefly detected then the user is removed. Sorry for this inconvenience.

I attempted following the instructions by creating a new list via outlook.live.com/tasks as suggested, but when I do and attempt to share the link, I get this error:

this was a brand new list I just created, and I waited several minutes before attempting to share because I got this error before and thought maybe I tried to share it too soon. on a new list, waiting several minutes got the same error. I click create invitation link again and this time it creates a link, but when I attempt to join the list via that link, I get the same error as above.

Hello SelAromDotNet,

Thank you for reaching out in Microsoft Q&A forum

I understand how frustrating it is that you and your wife can’t share a simple To Do list even after trying multiple devices, browsers, and reinstalling the app.

Sometimes a personal account can silently become a connected work/school account (for example after using Outlook.com with a domain or using Azure/Teams in the past). Please ask both of you to visit this page: https://account.microsoft.com/profile. If you see anything mentioning Work or school account, Azure, or Entra ID, that can block To Do sharing.

Since sharing To Do lists relies on Microsoft consumer identity services, please check: https://family.microsoft.com/. If:

either of you appears twice
one account shows “pending”
or you are not in the same family group

To Do sharing can fail exactly as you described. If so, remove the family group and re‑add it.

Another solution for you to try is reset To Do sharing permissions: Microsoft To Do uses the Tasks service under Outlook.com. Please try:

Go to https://outlook.live.com/tasks/
Delete the problematic shared list from there
Sign out on all devices then wait 2–3 minutes
Create a brand‑new list from this webpage
Share it again

This forces Outlook’s task service to re-register the list correctly.

Let me know how it goes.

I am having exactly the same problem. I have navigated to my mircosoft profile, and there is absolutely no reference to a work or school account, Azure, or Entra ID. I have navigated to family.microsoft and I have none of those issues you listed. For your 3rd solution, you said to navigate to Tasks under outlook.com.

You have then said to delete the problematic lists, but this is an absurd solution. My lists have a lot of information in them. Deleting the existing lists is not an option.

I also did a test whereby I created a new list from that webpage and tried to share it, and it still came up with the same error. So it doesn't matter if it's an existing list or a new one - it just does not share!

There is something seriously wrong in the back-end of to do that needs to be sorted immediately by Mircosoft.

Hi Jacqueline Feher,

Thank you for sharing this update. I completely understand your point, and your experience confirms that the issue is not account‑specific.

I’m seeing the same symptom across multiple recent threads. At the moment, the best next step is to submit in‑app feedback (To Do > Settings > Suggest a feature / Feedback) and also open a support request referencing that the join is briefly detected then the user is removed.

what exactly do you mean when you say "also open a support request"? because I can find absolutely NO PLACE ANYWHERE allowing me to create a support ticket for To Do to actually get HELP and a RESOLUTION as opposed to just report the problem.

Your documentation page here https://support.microsoft.com/en-us/office/get-help-for-microsoft-to-do-f4ea4cf4-0f36-4971-8f27-58fa0d247bd6 says that I can contact support via the app by clicking Get Support, but there is no such option.

Your documentation page here https://support.microsoft.com/en-us/office/report-abusive-content-in-shared-lists-a691caf7-6073-4cdf-9314-0f8c4352b83a says you can send an email to [email protected] (admittedly this specifies it's for abuse but I'm desperate to get ANYONE to help!) but guess what, that got bounced back as an inbox that does not exist!

I submitted a Feedback item: https://aka.ms/AAz5s5t but that's not support, it's literally collected as "Suggest a feature" as you just said, and I guess suggesting a feature that the app actually does it's BASIC FUNCTIONS seems silly...

Is this really the extent of support we are limited to here?

ah so the support link with the asp.net crash above started working, and I requested a call and actually got someone on the line. we shared screen and I showed him the complete issue from front to back and all error messages at which point I was promptly hung up on.

I did get a call back and we resumed, and after his numerous attempts duplicating exactly everything I already told him I had done, he confirmed that he could not help me, saying he was documenting the issue and submitting it to I guess a higher tier or escalation, I don't remember the words, but that I'd be hearing an update and hopefully a resolution soon.

about 15 minutes later I got an email alright, here's what it said:

Thank you for using Microsoft products and services, we appreciate your business. This email is to confirm that your support case has been closed.

isn't that great?

Hi Jamie Baldwin & SelAromDotNe,

Thank you for your updates.

As I've written above, I’m seeing the same symptom across multiple recent threads. At the moment, the best next step is to submit in‑app feedback (To Do > Settings > Suggest a feature / Feedback). But, if you can't find the "Help & Feedback" part in Settings, you can go to https://feedbackportal.microsoft.com/feedback and leave your feedback there. This will help the development team gather information and improve the service as quickly as possible.

While I can't directly verify our in-depth backend analysis, I'll do our best to support you within our responsibilities.

I sincerely apologize for any inconvenience you may have.

i think he's saying that the feedback hub IS the ONLY way to try and get a resolution, and that there is no support system for todo. if that's not what he's saying, that's definitely what's happening!

add, an apology doesnt cut it. We are embedded in using this as a field coordination system of tasks and items to complete. This is unacceptable and might I highlight this has been raised with Micrososft and it is now your responsibility to escalate this and get it fixed. This should not be a case by case "report it and fix it yourselves" scenario. This is an account and or tenant issue, and your technicians are able to resolve this without sharing our screens, without "shut down and restart" and need to get it done.

Pathetic service and useless help support that dont even know how their own systems work.
