Calendar sharing between two M365 tenants does not work although it has been configured

Pat_ITK · 20. August 2024

Dear Community,I'm hoping for your help after I got stuck with a problem and even a Microsoft support ticket couldn't solve the problem.I have a customer who owns a sister company, both companies have their own M365 tenant.Both companies want to share their calendars with each other and we strictly followed Microsoft's instructions to set this up tenant connection, sharing policy, etc. in both tenants.We checked the following KB articles among others:https://learn.microsoft.com/en-us/microsoft-365/admin/manage/share-calendars-with-external-users?view=o365-worldwidehttps://learn.microsoft.com

Hello!

Thank you for your reply.

It is not a bug.

Has been deleted by my description of the product key for Office 365 by the command line?

How does the behavior now?

hello + many thanks for your prompt + informative reply -- i presume the setting has to be 'Ursprüngliche Formatierung beibehalten (Standard)' in all categories, still it does not seem to work in my docus ...

cheers

Hello.
 Thank you for the answer.
 I think, if all does not work, I try the repair. It's a good advice.
 The first link is not what I meant and two other links do not work.
 But I eventually try the repair.

Ich vermute es liegt bei euch auch daran:

„Starting today, we’re blocking the ability to create a new personal Microsoft account using a work/school email address, when the email domain is configured in Azure AD.

What does this mean? If your organization uses Office 365 or other business services from Microsoft that rely on Azure AD, and if you’ve added a domain name to your Azure AD tenant, users will no longer be able to create a new
personal Microsoft account using an email address in your domain.

This sign-up block has been running in limited Preview for a hand full of organizations and is now active for all domains names that are configured (DNS-verified) in Azure AD. No action is necessary to enable the block.”

Hi Jason,

first the video failed when I tried to play it, although it had been working before. Then I tried to upload it again in different formats. That also failed. Don't know what to do...

Thanks for your answer!
