Additional chat-related features and issues within Microsoft Teams for business
Hi @Josh Mould
Welcome to Microsoft Q&A forum
I understand you are facing the issue that an inactive user still appears in Teams suggested chats.
To better understand, may I clarify a few details:
1.What version of Microsoft Teams are you using (e.g., Teams for work or school, desktop app version, web, mobile)?
2.What type of user accounts are affected (e.g., only disabled sign-in, or also converted to shared mailboxes)?
3.How long have they been in this inactive state?
4.Does this issue appear for all users in your organization, or only specific ones?
5.Are the inactive users visible in other Teams areas, like the member list of existing channels/groups, or just in suggested chats?
1.Verify User Account Status in Microsoft Entra ID:
-Log in to the Microsoft Entra admin center (entra.microsoft.com).
-Search for the affected user > Properties > Ensure "Account Enable" is unchecked.
-Under "Assigned roles" or "Licenses," confirm no active licenses are assigned (e.g., remove Microsoft 365 E3 if present).
2.Clear Teams cache:
-If Teams is still running, right-click the Teams icon on the taskbar, and then select Quit.
-Open the Run dialog box by pressing the Windows logo key +R.
-In the Run dialog box, enter:
%userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
-Select OK.
-Delete all files and folders in the directory.
-Restart Teams.
(Reference Clear the Teams client cache - Microsoft Teams | Microsoft Learn)
3.Review and Adjust Teams Privacy (optional)
As a workaround, you can block the inactive user from communicating with your organization. If you are an IT admin with appropriate permissions, follow these steps:
-Log in to the Teams admin center (admin.teams.microsoft.com).
-Navigate to Users > External access.
-Locate and enable the option Block specific users from communicating with people in my organization by toggling it to On.
-Click Block a user, then enter the email address of the inactive user.
-Click Save to apply the changes.
Additionally, if you have recently inactivated the user, Teams may need some time to sync these updates across the system depending on the environment and any ongoing directory sync processes. If the user still appears in suggested chats shortly after inactivation, please allow additional time for the changes to propagate fully, and consider clearing the Teams cache again if needed.
The initial response may not fully address your needs, but it will help me better understand your situation and try to find the root causes. Thank you for your patience while we work through it
