Hello!

We are on office 365 plan E3 and everything works well. we can assign tasks in between each other correctly. 

We'd like to do the same with users from a different organization, also on exchange, version 2010. 

the task is received as an attachment and doesn't display correctly, i don't have the options to accept or or reject the task



What can i do? 

Thanks!

Hi Gabriel,

Thank you for your question.

Could you tell me another Exchange version?

We could run the following command to check if the issue persist:

Set-RemoteDomain -Identity <Remote Domain> -TNEFEnabled $true

If not, post issued task to us for troubleshooting.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
