Hi @Zaid Pirwani ,
Welcome to our forum.
Does this issue occur with all POP users?
Agree with RobertSparnaaij, considering the size of the .pst file is large, the import process may take a long time. Please wait patiently.
For this, it's also suggested that you could export the emails to several slightly smaller .pst files, which facilitates import.
And I noticed that, for the "AZURE PREMIUM P1 Support TRIAL" you mentioned, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client and know little about that. If you need more help about "AZURE PREMIUM P1 Support TRIAL", please contact the support of it for more professional suggestions.
In addition, considering that the screenshot you provided contains personal information, I have hidden it in order to avoid privacy disclosure. Please remember to hide your personal information before uploading.
