Hello Frank Sweeney,

Where in Teams do you see “Can’t sync right now”: the calendar, chats, or files? Also, are you using Teams Free or a work or school account, and is this in the desktop app, browser, or mobile app?

The existing answer covers refreshing and restarting Teams. If you’ve tried those, the details above will help narrow down what is failing to sync.

Thank you, Thomas4 - N. Unfortunately, I've tried all those suggestions without any success. I'm using MS 365 Family edition. So, not free, but basic.

Hello Frank Sweeney,

Thanks for the reply. Microsoft 365 Family can be used with Teams for personal use, so the subscription name alone doesn’t tell us what is failing to sync.

Where do you see “Can’t sync right now”: in chats, the calendar, or somewhere else? Also, does the same message appear when you sign in to Teams in a browser with the same account? That comparison should help narrow down whether this is limited to the app.

Sorry Thomas 4-N It appears at the top of an appointment in my Teams Calendar when I try to see or edit the details.

thanks for continuing interest.

Hello Frank Sweeney,

I understand the message appears when you open an appointment in your Teams Calendar to view or edit its details, rather than in chats or files.

Could you sign in to Teams in a browser with the same account and open that same appointment? Let me know whether its details open there or whether you see the same sync message.

If Teams shows "can't sync right now. We'll try again soon", try these steps:

In Teams, look for a banner at the top of the app and select Refresh. This restarts the app sync process.
If that does not help, manually restart Teams:
- Windows: right-click the Teams icon in the taskbar and select Quit
- Mac: right-click the Teams icon in the dock and select Quit Then open Teams again.
On mobile, open Teams and pull down to refresh messages.
If the issue is with files syncing in Teams or SharePoint libraries, check for these common causes:
- Files showing a lock icon in File Explorer are synced read-only. This can happen if edit permission is missing, checkout is required, or required columns/metadata are configured.
- If the library has Require Check Out enabled, Required columns, or Draft Item Security set incorrectly, syncing can fail.
- Syncing with a guest or external account is not supported for this scenario; use an internal organizational account.
If the problem is with a Schoology-linked Teams assignment, open the course and go to Teams Assignments to check whether the status is Synced, Not Synced, or Error. Not Synced or Error may require help from an IT administrator.

If the issue continues after refresh and restart, and especially if files are involved, the sync configuration or permissions likely need to be corrected.
