We have enabled HMA for our organisation. It works for 3000 users, they are able to connect and see the four weeks of email in their Outlook Mobile App. For some reason we have 70 users that are able to connect via Outlook Mobile and get a first sync of
e-mail. But it al stops and no new email will show up in the Outlook App.
We have checked the IIS logs on the internal exchange servers.
In the ActiveSync log I see that from O365 a full hierarchy sync is requested. According to the Exchange and IIS logs, this is done correctly and then it request the full hierarchy again and again.
Does somebody had the same issue and have any ideas how to get the sync reset to a working state.
Would you please provide a more detailed Activesync log of yours? Do you mean that new emails won't show up in the 70 users' Outlook mobile app after enabling HMA?
The full hierarchy sync seem to be related to public folder which means the process of copying the public folder hierarchy between public folder mailboxes. The hierarchy replication is always from primary hierarchy public folder mailbox to secondary hierarchy
mailboxes.
