Follow the listed guidelines in order to resolve the issue. The methods are listed in easy to hard order.
Method 1:- Uncheck Offline Mode
Most often it is possible that the outlook is set to offline mode. For people using versions less than 2007 then simply click on File and check if the Work Offline is selected or not.
For newer versions:-
- Click on the “Send/Receive” option.
- Search for “Work Offline”
- Set the parameter to Online.
If the screen shows “Trying to connect” then your issue is resolved otherwise you should try another method.
Method 2:- Restarting your Outlook
One of the most simple but effective solutions is restarting outlook. It may sound funny but it yields results most of the time.
If this doesn’t work, you may try restarting your device as well. This may solve the connectivity issues of your device if you have any.
Method 3:- Rebuild your Data Files
Walkthrough the below-listed steps and figure out if this works for you. (Outlook uses .pst and .ost types of files.)
- Close the Outlook Application.
- For Windows open the control panel by clicking on start and searching the same.
- Click on the mail icon present over there.
- In the new window, click the “Data Files” button
- Search the file which has the same name as your email address.
- Click the “Open File Location…” tab
- If your file is a .ost file, then give a right-click on it to rename the extension to.OLD. If your file is .pst, do not change anything.
- Reopen outlook after closing all the windows currently opened.
The process takes 10 minutes as outlook starts recreating your files. You must not quit your application till this process goes on.
After the completion of the process a message stating “All folders are up to date” will appear.
If you have a .pst file, then you should follow the steps below:
- Type scanpst.exe in the search box of C:\Program Files or C:\Program Files (x86)
- Double click on the file to run the application
- Your default .pst or .ost file should already be selected
- Click Start
Ensure checking to “Make a backup of scan file before repairing”. If the problem is still on your back try another method. After the completion of the process try reopening the Outlook and check if the error still persists.
