Office365 account disconnects (only the account that needs two-factor authentication)

Similar thing for me with 1.9 snap. My office365 school account disconnects within minutes of setting it up again. Downloads everything fine at first, but then gives that error and does not reconnect.

Odd thing is when I connect the account, it doesn’t go through 2-factor authentication (university uses Duo security). I wonder if that has something to do with it?

Issue seems to start with error messages in the logs of “Local model is not present”

Generally, logs show:

and then eventually gives:

*** Mailspring Sync

I believe this has to do with a change earlier this year by Microsoft on how token lifetimes can be configured, which would explain why it’s behaving differently per organization.

Configurable token lifetimes

I believe the reason for the token lifetime to only be 24 hours is that the Mailspring application is registered as a Single Page Application at Microsoft. Look at this post under the other thread:

Could mailspring refresh this token before it expires? This is such a nice email client, but this bug is infuriating.


Same here. Please fix this! I have been using Thunderbird until this issue is resolved, I love mailspring and want to come back to it!

Any update on this? Its been a year since this issue was first opened and it still hasn’t been resolved. I’m surprised this wasn’t a higher priority given that many people use office365/exchange accounts, especially for schools. I really want to use mailspring again as my email client.

If there is anything further that maybe I could provide I can try my best too.

Yes, its a beautiful client— but in the end office365 mail does not work with it.
Although— everytime I click “Sync Now” it seems to reconnect. But definitely not a reliable solution

Hey guys!
I was able to get around this issue by adding my account using IMAP/SMTP.
When adding your account, instead of selecting Office 365, select IMAP/SMTP at the bottom.

Then set your incoming and outgoing mail server details as below:
Incoming Mail (IMAP):
Server name:
Port: 993
Encryption method: TLS

Outgoing Mail (SMTP):
Server name:
Port: 587
Encryption method: STARTTLS

Before I had to manually reconnect every morning after starting my PC, but after this configuration, it never got disconnected and it’s been a few days now.

This will only work for users that are within a tenant that specifically allows this.

I really liked this application; however, this issue is very bored.

I am using GNU/Linux Debian Stable on three machines (two laptops and one desktop), and I’ve added the Office 365 business account because of my work. This work very well, but I have the “Cannot authenticate with "account” message all the time.

Checking the log file:

Do you have some date to resolve it?

Thank you.
