Hi All,
On March 20, an Exchange Server 2010 was patched with KB5000978 (the latest patch issued on March 2).
From March 24 onwards, the Outlook App in Android phone has not got any new email. No new email could be sent. Also, the old email in Inbox could not be forwarded. No error message was prompted. The Android version is 8.1 and 9.
When the Outlook App was removed and then re-installed, it worked for the first time and then did not function again.
Please help.

Sorry I need to ask a few questions:
- Do you have some IOS clients using Outlook for IOS to connect to the Exchange 2010 server in your organization? Do they work fine or do they have the same problem?
- Did you update the Outlook app before the problem occurred?
You may use the ExRCA tool which is a Microsoft online tool to test if activesync is working fine.
If activesync is working fine, I suppose that the problem may be with the Outlook for Android application.
Here is also a link in the similar situation for your reference: Outlook Mobile App not connecting to Exchange 2010 as of 26/03/21 -
