Sync job with Office365

Ssud0nz · 18 Feb

Hi all,

I’m trying to sync my old emails (hosted in Office365) to Mailcow. The docs

docs.mailcow.email

Sync job migration - mailcow: dockerized documentation

None

are very simple and don’t provide much help.

The error I’m having is:

Host2: connecting and login on host2 [localhost] port [993] with user [lucas@example.com*XXXXXXX@mailcow.local]
Host2 IP address: ::1

I would guess you did not setup your account on Office365 correctly. This sync service is simple IMAP under hood,.. so try to use IMAP LOGIN outside MC, until you will be able to, it’s not MC problem,…

You need to check the imapsync documentation:

Q. How to sync from Office365 to XXX?

R. On Windows, use:

  imapsync.exe ... --office1

On Unix, use:

  imapsync ... --office1

Option --office1 is like (release 1.970 or higher):
  
  imapsync ... --host1 outlook.office365.com \
               --ssl1 \
               --exclude "^Files$"

So you are missing the custom parameter --office1
If that doesnt work you need to create an app password on MS365, or use OAUTH2 token:

I guess its simpler to move the mails with a PST file to your mailcow account.
