Hello,
Hope you are doing well. Thank you for reaching out to the Microsoft community.
I read your thread and get some basic information of your scenario. To better understand and investigate your issue, I may need some more detailed information from your side so that I can narrow down the issue in right way:
- May I please know if you are using Microsoft 365 business/education email account, Microsoft personal account such as Outlook.com, hotmail.com or live.com, or other third-party/custom domain email?
- Does the issue occur using a different email account?
- Is the issue is happening with outlook client application or outlook on the web also?
- Is this the first time that this have happened on your device?
- Kindly mention when this situation started to occur
With this information, I will be able to investigate further and provide you with the most accurate solution.
As an initial troubleshooting, please [reconfigure]your account or remove and re-add your account from the devices and check if the issue will persist. We also like you to try other Microsoft account as well.
Thank you in advance for your understanding. Your patience and cooperation will be greatly appreciated. I hope for all the best!
Sincerely,
Nafis Iqbal Shuvo
