I'm migrating mailbox to Office 365 and got stuck with Large Items Exception.

I read about default message size restrictions. And set 100MB limit in Exchange Online.

Then migration failed again. I checked large item. It is around 40MB. So just above previous size restriction.

Since then I've tried to find any place where 35MB old limit is applied. Either on-premise or in cloud. And the only place I found is Mailuser in cloud. It's Mailuser because mailbox is still on-premise

The command run in Exchange Online. enter image description here

I've confirmed that. After migration large item was skipped. And cloud mailbox MaxSendSize and MaxReceiveSize were 35 and 36 respectfully. Where they should have been 100MB as default message size restriction.

Could you please help? Maybe you know where this numbers are coming from. Or some policy for migration message size. I'd appreciate any thoughts.

Update 12.02.20. It seems to work after disabling data-loss prevention policy. We had Office 365 Security and Compliance DLP scanning Exchange mail. After deleting this, migration works, and message size restriction is back to default setting of 100MB for newly migrated mailbox. Maybe DLP freezes this restriction, I don't know.

Serverfaulters.

Short: I'd like to publish several SFTP servers through one server (reverse proxy/relay). How could I do that?

Long: there are three components:

                                    ----> sftp-server1.local
                                    |     port: 22
Filezilla  ----> sftp-proxy.org ----
SFTP client      port: 22           |
                                    ----> sftp-server2.local
                                          port: 22
  • Filezilla - SFTP client
  • sftp-proxy.org - available from the internet server
  • sftp-server*.local - internal SFTP servers
  • sftp-user* - user accounts on SFTP servers

Case: internet user opens Filezilla, enters sftp-proxy.org with login sftp-user1 and gets on sftp-server1.local. Another user enters sftp-proxy.org with login sftp-user2 and gets on sftp-server2.local. So SFTP-proxy.org redirects user to internal SFTP server based on his username.

I've found this sshd_config for sftp-proxy.org:

Match User sftp-user1
    ForceCommand ssh -t [email protected] $SSH_ORIGINAL_COMMAND
Match User sftp-user2
    ForceCommand ssh -t [email protected] $SSH_ORIGINAL_COMMAND

But they say it won't work, is that so?

Note: I would like to find the solution that client is user friendly (default Filezilla, no ssh options).

ssh sftp reverse-proxy
