Problem
Microsoft licensee is receiving multiple meeting acceptances for the same meeting, this can be a frustrating issue. It is often caused by a synchronization problem between Outlook and iPhone users.
Description
As of now, the only way to resolve this is by having the person that sent the invites remove the calendar from their iPhone. This is not a solution, more of a work around until Microsoft and Apple fix this.
Resolution
1. Go to settings
2. Scroll down and click Apps
3. Click Mail
3. Tap Mail Accounts
4. Tap on the email account sending the acceptance email
5. Turn off the calendar, you will get a message that says " Turn off calendars, are you sure you want to continue? All exchange calendars will be removed from your iPhone". Click ok. tap on delete calendars.
6. Give it 30-seconds, you can then go back into Settings and turn it back on. All the appointments will reappear to your phone, but should stop it from sending any more acceptance emails.
