The Exchange server won't let us connect
I have one user, where the SfB client won't connect to the Exchange mailbox in Exchange Online
This is the error message
'The Exchange server won't let us connect. We're working on fixing the connection. Your history, voice mail and Outlook features might be unavailable or out-of-date until things are fixed.'
Other users on the same On-Premisses SfB pool, with an Exchange Online mailbox are working
Any ideas of what the problem might be?
- The error was the user had over 3000 folders in his mailbox
Found with PowerShell: (Get-MailboxFolderStatistics -id user@contoso.com).Count- Thanks, the same thing here. I'll be requesting the action.
- I have a similar issue with single user, I already re-create outlook profile, full delete Skype profile even the records in regedit, check the personal certificate Communications Server, I moved the account to other SfB pool, ipconfig /flushdns and not works.. next step is execute the next command just to test:
How to Troubleshoot Time Server Synchronization Problems
If you're finding issues coming up because your local PC has a different time than the server it is syncing to, you can reset the Windows Time service configurations using Command Prompt.
Open the Start menu.
Search for cmd.exe, right-click the result, and select Run as administrator.
Type the following command to disable the Windows Time service and press Enter: net stop w32time
Type the following command to unregister the Windows Time service and to remove all settings information from the registry and press Enter: w32tm /unregister
Type the following command to register the Windows Time service and to load the default settings to the registry and press Enter: w32tm /register
Type the following command to start the Windows Time service and press Enter: net start w32time
Type the following command to force your computer to synchronize your computer without waiting and press Enter: w32tm /resync /nowait
Restart your computer
if not works.. I'll be continue with this commans:
outlook.exe /cleanroamedprefs
This switch command cleans (and copies again) your Outlook roaming preferences from the local settings of the PC on which it is run.
Roaming settings are a small collection of settings that govern reminders, the Free/Busy grid, working hours, calendar publishing, and RSS rules.
Settings running on Exchange Server can change during an Outlook session. Normally, as soon as new settings become available, they are updated for the user client. Unfortunately, in certain cases, this doesn’t happen, leading to various problems. Running Outlook.exe /cleanroamedprefs should fix the problem.
I'll let you know if this works, if you have any troubleshoot, please share it.
Greetings
