Comments not saving

i have the same issue now aswell, the strange thing is that when i place a comment, the comments are saved when i reopen the task. But when my colleagues place any comment it dissapeared after we reopen the task.

We are using this for a few years and it always worked but since last friday it stopped working.


Update: i found the problem, when teams are created, an email address is automatically created. Since this mailbox is not maintained, I had blocked everyone in our company from sending emails to this email address except myself. Apparently this email address is required to post comments and notes within microsoft planner.

U can find the setting at the exchange admin portal, then: Groups>search for your teamname>Settings> Edit delivery management> then check if you have right to use this mailadres
