According to your description, I understand that your exchange accounts have any sync and blocking issues on your outlook for android, but they could work normally on your Outlook for PC, is it right? If so, the issue may be more related to your Outlook for Android itself, please kindly understand here we mainly focus on general issue on Outlook desktop client, in order to resolve your issue better, please post your issue in this dedicated forum for Outlook for Android, thanks for your understanding and hope your issue would be resolved soon.
Hope that would be helpful to you.
