Work uses O365 and I’m getting a little frustrated with OWA. Thinking about running a local email server to mirror O365. In the end, I want to keep my email in O365, but have a 2 way sync with a local imap server. Looks like I have a few options on the email server - dovecot/cyrus/stalwart. For the syncing, I just see mbsync. Any experience setting up something similar? Any other options other than what I listed?
Edit: IT knows what I’m doing. I’m not going to compromise any compliance requirements we have.
No, oh god no. What you are talking about can arguably be classified as Shadow IT and can get you into trouble depending on your orgs certifications.
If you have O365 that should entitle you to Outlook and use that instead or ask your org IT what alternatives they permit.
