How to view old messages on skype for mobile or PC if you use an old version of Skype
If for some reason you have an old version of skype, then the instructions given above will not work.
In the previous Skype versions, all old messages were being archived after some time. This was done in order to not clutter up the screen with outdated messages and free up the program resources. At the same time, the archived messages were not being deleted, so you could view them if necessary.
The exception is the situation when you manually deleted your messages – then it will be impossible to see old chat history.
So, here’s how to view the archived messages in the older version of Skype. The following sequence of actions works for all devices and operating systems:
01. Launch Skype on your device
02. Log in to your Skype account, in which you plan to view the message history you need
03. Go to the “Contacts” tab in the main program menu

04. Select the contact you want to view the conversation history with. If you don’t see the chat you need, use the chat search by typing the first letters of the contact’s name.
05. Click the “Conversation” tab at the top of the screen and then select the “View old messages” option.
06. In the drop-down list you can select any period of time during which the conversation you are looking for took place.

07. Select the desired period by clicking on it.
08. Also, if you need to view the old messages on a specific topic or keywords, you can select the “Find” option located in the same tab as the “View Old Messages”. In this case, Skype will display all mentions of the words you set for the entire available period of communication with the contact.
