Flow Access Token Expires After 90 Days, Breaks Entire Flow For Some Users

Hi there,


I have a PowerApps app that executes a flow upon a button being pressed. The Flow is supposed to send an email to the user. The issue is, when a user has not used the app for 90 days, they get the following 'Unauthorised" error message:


Error from token exchange: Runtime call was blocked because connection has error status: Enabled| Error, and office365 is in the block list. Connection errors: [ParameterName: token, Error: Code: Unauthorized, Message: 'Failed to refresh access token for service: office365certificate. Correlation Id=acd8bb0e-ca12-4a5c-b296-8976d31c935c, UTC TimeStamp=1/21/2019 9:58:54 PM, Error: Failed to acquire token from AAD: AADSTS70002: Error validating credentials. AADSTS700082: The refresh token has expired due to inactivity. The token was issued on 2018-09-17T20:50:04.6944271Z and was inactive for 90.00:00:00.

Trace ID: 6cd56f54-aa12-4106-ba85-1fb1eab86d00

Correlation ID: 4baaa3da-444a-4cda-b5d8-8e5058ba8099

Timestamp: 2019-01-21 21:58:54Z']


i.e. If they are inactive for 90 days, their access token is revoked. 


Even after signing into the app this issue persists, unless i make an entirely new flow. This seems pretty ridiculous for me to have to do after 90 days of inactivity for any one of the users.


Short of messing around with the expiry time of the tokens, of which i have no knowledge, how can i allow a user to use the flow without having to worry about an expiry time?

Hi @Toasteroven,


Yes, the Flow Access Token Expires After 90 Days as you said.

I afraid that there is no any way to prevent the Access Token Expires, so you could only update or create a new connection to the connector bepore the Flow Access Token Expires.

And you needn't create a new flow to troubleshoting the problem. Link below could be your reference for managing connections:


Best regards,


How would i go about "update or create a new connection to the connector bepore the Flow Access Token Expires"


Is there a way to automate this so I dont have to manually fix it every 3 months?


I can see no option to update the connector

Hi @Toasteroven,


If a connection is expired, you could fix the connection.

And if the connection isn't expired, you could create a new connection.
